It probably developed during two fragmentation events and possibly from a silica gel precursor that crystallized after precipitation. The proposed quantitative control of crystallization can be an effective mass amplification strategy for QCM to enhance its assay sensitivity. Resolution of the age and probable magmatic source of the Butte pre-Main Stage porphyry copper-molybdenum system and of the silver-rich polymetallic quartz vein systems in the northern part of the Boulder batholith documents that these deposits formed from two discrete periods of hydrothermal mineralization related to two discrete magmatic events. These veins occur in swarms, and are hosted along structures that are, Geology and lithogeochemistry of the Ren gold prospect, Elko County, Nevada - the role of rock sampling in exploration for deep Carlin-type deposits. Successful cultivation and FISH analyses strongly supported that these thermophilic lithotrophic microorganisms could be exactly active and they grew using geochemically produced hydrogen and methane gasses as nutrients. On the valley floors, recent alluvium and pediment deposits overlie the bedrock. Gold mineralisation in the SULDT occurred during a transition from compression to strike-slip deformation coeval with a regional pulse of orogenic magmatism [10]. of magma emplacement. Webatmatm24365atm 14488 Ma but mostly 11092 Ma) xenotime (10493 Ma). ), and variable liquid/vapor ratios. Alteration zones of type 2 are strongly potassium-enriched and pyrophyllite, kaolinite, illite, gypsum and quartz occur. Orogenesis, high-T thermal events, and gold vein formation within metamorphic rocks of the Alaskan Cordillera. Full Members Following a bumpy launch week that saw frequent server trouble and bloated player queues, Blizzard has announced that over 25 million Overwatch 2 players have logged on in its first 10 days. These minerals, together with epidote and chlorite, occur mainly within cm-wide veins (N40E-N60E) and irregular open spaces. The Niassa Gold Belt, in northernmost Mozambique, is hosted in the Txitonga Group, a Neoproterozoic rift sequence overlying Paleoproterozoic crust of the Congo-Tanzania Craton and deformed during the Pan-African Orogeny. On the other hand, in Yani only 40% have concentrations above 2 g/g THg, with an average value of 2.34 g/g THg. The manufacturing process of molds for patterned media is almost the same as that for semiconductors, with the exception of the dry-etching process. In the Red Hill deposit, alteration is complicated due to multiple overprinting hydrothermal events and is characteristically affected by pervasive, pink quartz-K-feldspar-hematite alteration which is overprinted by potassic alteration characterized by a quartz-biotite-carbonate-muscovite/sericite-rutile-apatite assemblage. In addition, 7,257 oz (226 kg) of gold and 350 oz (11 kg) silver were produced at the Tower mine, near the area. Such formation depths are in good agreement with the regional geological evolution. Au contents in area 1 range between 0.12 and 14.91 ppm, and between 6.1 and 16.3 ppm in area 2, while gold values in area 3 vary from <0.01 to 0.03 ppm. This produces a sample that most closely replicates the protolith of extensional shear zones that typically develop under retrograde conditions. Spentzouris, G; Gasparis, A; Scriven, R J; Lee, T K; Labropoulos, N. To determine the natural history of deep vein thrombosis in children presented with a first episode in the lower extremity veins. Varimax factor analysis of bulk compositions of these samples reveals geochemically distinct element groupings that reflect statistical associations of monazite, allanite, and xenotime; biotite and gold; detrital minerals; chalcopyrite and sparse stannite; quartz; and cobaltite with sparse selenides and tellurides. Most gold deposits therein are associated with major deformation corridors; the east-west oriented "Mine trend" hosts most of the large deposits and the northeast-southwest "East Bay trend" hosts several small deposits and showings. ?C and 200 to 300??? EGI Presents: MAKE ME AN OFFER! Massive pulmonary embolism caused by internal iliac vein thrombosis with free-floating thrombus formation in the inferior vena cava. However, epithermal ore veins that we observe today are the results of a great number of intermittent upwelling of overpressured fluids with different pressures. Experimental study of quartz inclusions in garnet at pressures up to 3.0 GPa: evaluating validity of the quartz-in-garnet inclusion elastic thermobarometer. The ore bodies show a fairly simple shape and mainly occur as tungsten-tin polymetallic-bearing sulfide quartz veins, including quartz vein, quartz-greisens, and sulfide quartz veins, and their distribution is spatially related to Dajinshan granitoids. The veins consist chiefly of quartz; pyrite is the chief metallic mineral and chalcopyrite is next in abundance. The hypogene zone has differentiated alteration types; high potassic and low phyllic alteration, while the oxidation/supergene zone has high phyllic and propylitic alterations. This facies leads to the destruction of any biomarkers and explains why the extraction of hydrocarbon biomarkers from pristine drill cores has not been successful. ?C at pressures of less than 2 kbar. The Dajinshan tungsten-tin polymetallic deposit is a quartz-vein-type ore deposit located in Western Guangdong Province. favorite this post Aug 3 Vintage Ethan Allen American Impressions Buffet FREE Local Delivery. healthyroadsmedia. When exposed to electromagnetic radiation occurs at the receiver thermal field which causes mechanical stress in the transient crystalline quartz, which in turn leads to a change in the polarization of crystalline quartz and, as a consequence, to an electric potential difference at the electrodes (the front surface with a conductive coating and damper). The thermal history of the Lucia subterrane has been previously proposed by Underwood et al. Taylor, Ryan D.; Goldfarb, Richard J.; Monecke, Thomas; Fletcher, Ian R.; Cosca, Michael A.; Kelly, Nigel M. The Grass Valley orogenic gold district in the Sierra Nevada foothills province, central California, the largest historic gold producer of the North American Cordillera, comprises both steeply dipping east-west (E-W) veins located along lithologic contacts in accreted ca. In the southern part of the Eastern Desert of Egypt, Landsat Thematic Mapper (ETM+) data and fieldwork was combined with mineralogical and geochemical investigations in order to detect and characterize alteration zones within Pan-African rocks. The Alaska-Juneau lode system is confined exclusively to the footwall portion of the Perseverance slate band. Quartz substrate more suitable for waveguide circuits than GaAs substrate. Fluid inclusion trapping conditions are estimated to be 250?? The assessment of spatial relationships between the location, abundance and size of orogenic-gold deposits in the highly endowed Sierra Foothills gold province in California, via the combination of field studies and a GIS-based analysis, illustrates the power of such an approach to the characterisation of important parameters of mineral systems, and the prediction of districts likely to host economic mineralisation. ?18O(H2O) values suggesting dilution by variably exchanged meteoric waters. A suite of samples was collected from the newly exposed orebody for preliminary mineralogic, stable isotope, fluid inclusion, and geochemical studies. The average Ti-in-quartz concentration from the synthesis experiment is 392 1 ppmw Ti, which is within 95 % confidence interval of data from the 10 kbar isobar of Wark and Watson (Contrib Mineral Petrol 152:743-754, 2006) and Thomas et al. TitaniQ in reverse: backing out the equilibrium solubility of titanium in quartz, There is close agreement among three of the four experimental studies that have 'calibrated' the P-T dependencies of Ti-in-quartz solubility. In spite of innumerable associated injuries, portal vein injuries can be successfully managed in a significant number of patients using generally available surgical techniques and several adjunctive maneuvers. If some regions, such as the SW of Ghana, are well known for world-class mineralizations and have been extensively studied, gold occurrences elsewhere in the craton have been discovered only in the last half a century or so, and very little is known about them. The Bansk Hodrua mineralization was formed during four stages: (1) low-grade silicified breccia at subhorizontal structures at the base of the deposit; (2) stockwork of steep veins with rhodonite-rhodochrosite, quartz-sulphide-carbonate and quartz-gold assemblages; (3) thin quartz-gold veins with medium dip in tension cracks inside the shear zone and complementary detachment hosted quartz-base metals-gold veins; (4) Post-ore veins. Low DH2O values of -120 to -130 per mil for a hydrous muscovite from the Sheba vein in the Klondike district reflect secondary exchange between recrystallizing mica and meteoric waters. Petroscopic analysis and interpretation of the samples were done by Gootee. The RVO pathogenesis has varied systemic and local implications that make it difficult to elaborate treatment guidelines. The orebodies are characterised by micro-breccias and zones of intense shear zone foliation, very high gold grades (up to 100,000 g/t Au) and the common association of tellurides and vanadian mica (green leader). Mutant true leaves did not possess the qualitative venation anomalies previously shown in the cotyledons, but varied quantitatively in vein traits and leaf anatomy across genotypes. Gold deposits were either hardrock (lode, gold-quartz veins) or placer (alluvial, unconsolidated gravels). In addition, background alteration includes greenschist, subgreenschist, and zeolite facies minerals. 10 Fig. Most deposits are hosted in uplifted blocks of Precambrian metamorphic rocks, although felsic Paleozoic and Mesozoic plutons are typically proximal and host ?? In addition, the detection of the presence of gold is feasible with no background levels in the body in the normal situation. The visibility of veins eligible for cannulation increased for all subgroups using a new infrared device. Thus the ore bodies are found in and near the terminations of meta-gabbro bodies. Given the overlap in age between the G4 granites and the mineralized quartz veins, and the typical association of the W deposits in Rwanda, but also worldwide, with granite intrusions, W originated from the geochemically specialized G4 granites. Attempts in our laboratory to weaken crystals in a gas-medium apparatus at around 300 MPa by cooking dry quartz in the presence of added water were all unsuccessful, although we could deform wet synthetic crystals. In contrast, previous studies in other systems had reported higher ratios of tracheary to sieve elements and higher transpiration rate to be associated with higher - rather than lower - vein densities. Additionally, we attempted to achieve a dense hole (HOLE) pattern at 12.5 nmhp for BPM for use in 2012. At the Lac Herbin deposit, the aqueous-carbonic inclusions are interpreted to have formed first and to represent the gold-bearing fluid, which were generated contemporaneous with regional greenschist facies metamorphism. The hydrothermal deposits include many metalliferous quartz veins most of which occur in three mineralized areas: two major areas at Jabal Ash Shumta and Jabal El Khom in the northern half of the quadrangle and a minor area along Wadj al Boharah in the southeastern part of the quadrangle. Most aplite, pegmatite, and quartz dikes in the area are thin and discontinuous and are intruded along the vein trend. ; Snee, L.W. Electromagnetic, magnetic, and gravimetric surveys at the Bi'r Jarbuah gold prospect, Kingdom of Saudi Arabia. The emplacement of the quartz veins resulted in an alteration of the metasedimentary and granitic host-rocks, mainly resulting in muscovitization, tourmalinization and silicification. Hydrothermal activity was characterized by intense enrichment in alteration zones of carbonates, sulfides, chlorite, white micabiotite, albite and quartz, as described in other Archean lode-type gold ores. After the experiments, the samples were vacuum impregnated with a low viscosity epoxy containing a blue dye. Noble Gas Isotope Evidence for Mantle Volatiles in the Cu-Mo Porphyry and Main Stage Polymetallic Veins at Butte, Montana. Webatmatm24365atm Coarse muscovite veins and alteration deep in the Yerington batholith, Nevada: insights into fluid exsolution in the roots of porphyry copper systems. Textural analysis of gold nuggets was made by means mechanical sieving and visual comparison of roundness and form. The extracted thermodynamic standard state properties of annite were used to calculate annite and annite+quartz stabilities for pressures between 2 and 5 kbar. Disks were made of single crystals of synthetic and Brazilian quartz. All these results suggest that the Lucia subterrane underwent a regional increase of thermal gradient toward the north. The PALSAR image was enhanced for fracture mapping using the second moment co-occurrence filter. Over 50 veins and mineralized breccias ranging up to 2 m in width and having a strike length up to 500 m contain from trace to 13.0 ppm gold. ; Bradley, D.; Johnson, Chad; McClelland, W. The Donlin Creek gold deposit, southwestern Alaska, has an indicated and inferred resource of approximately 25 million ounces (Moz) Au at a cutoff grade of 1.5 g/t. ? These veins record both synmetamorphic internal fluid release by mineral breakdown reactions (type I veins) as well as infiltration of an external fluid (type II veins) and the associated formation of a reaction halo. Ester Dome, an upland area near Fairbanks, Alaska, was chosen for a detailed hydrogeochemical study because of the previously reported elevated arsenic in groundwater, and the presence of a large set of wells amenable to detailed sampling. Goethite adsorption was measured quantitatively by Fourier-transform infrared spectroscopy. These were isoclinally folded and metamorphosed prior to gold mineralization. ?C prior to 10 Ma. Stishovite occurs as euhedral acicular crystals, typically <0.5 m wide and up to 15 m in length, associated with clast-matrix or shock vein margin-matrix interfaces. Native gold is associated with galena, altaite, hunchunite, nickeline and rare cobaltite, Pb-bearing maldonite, pyrite, pyrrhotite, chalcopyrite, molybdenite and titanite. The Butte porphyry-vein system is associated with quartz monzonite stocks and dikes within the southwest part of the Late Cretaceous Boulder batholith. Laser therapy remains the gold standard in RVO, but only modest functional improvement has been shown in branch retinal occlusion forms. Geochemical and mineralogical characterization of the abandoned Valzinco (lead-zinc) and Mitchell (gold) mine sites prior to reclamation, Spotsylvania County, Virginia. The adsorption of colloidal goethite onto quartz and kaolinite substrates has been studied as a function of pH and NaCl concentration. The Spinifex Fault trends ~065 across an outcropping granitic pluton, the margins of which it offsets dextrally by ~0.75 km. Experimental charges consisted of amorphous silica powder (30 mg) to provide a source of silica for the quartz cement, AlCl3 powder (3 mg) to provide a tracer for Cathodoluminescence (CL) identification of cement formed during the experiment, 25 wt% NaCl brine solution (25 mg) to increase the silica solubility and to better mimic oil field brines, and the natural quartz grains (100-130 mg). There is evidence that gold mineralisation in the Western Lodes (which occurred at ca 2655 Ma) post-dates the majority of displacement along the Sunrise Shear Zone, but it remains uncertain if the ore in both structures formed simultaneously or separately. An external vein stripper is an extravascular device used to remove a section of 21 Food and Drugs 8 2014-04-01 2014-04-01 false External vein stripper. Both vein types are associated with small alteration zones, comprising silicification, tourmalinization, and muscovitization. arm still hurts from covid vaccine months later. Tentative explanatory variable of lung dust concentration in gold miners exposed to crystalline silica. Without compromising the R0 rate, transverse closure to reconstruct the mesenteric-portal vein is shown to be feasible and safe in the setting when a short segment of vein resection is required during pancreatoduodenectomy. Mercury pollution from the artisanal mining in Yani gold district, Northern Bolivia, Alfonso, Pura; Freixas, Anna; Bascompta, Marc; Mara Aranibar, Ana; Villegas, Karla; Mara Garca-Noguero, Eva; Higueras, Pablo; Cielito Saraiva, Angela, Artisanal gold mining is the main economic activity in the Yani district, Northern Bolivia. Fox Files Addition of -amylase to the solution resulted in the rapid degradation of the films. The orebodies have a long axis parallel to the local stretching lineation, with continuity down the plunge of fold axis for at least 4.8km. New joints initiated upon emplacement of the, First Evidence of Epithermal Gold Occurrences in the SE Afar Rift, Republic of Djibouti, Moussa, Nima; Fouquet, Yves; Caminiti, Antoine Marie; Le Gall, Bernard; Rolet, Joel; Bohn, Marcel; Etoubleau, Joel; Delacourt, Christophe; Jalludin, Mohamed, The Republic of Djibouti, located at the SE part of the Afar volcanic Triangle, is characterized by intense tectonic and bimodal volcanic activity, and is emplaced over an earlier magmatic rift system, as old as 25-30 Ma. The district is characterised by a protracted deformation history associated with four main deformation events: D1S is a N-S compression; D2S is an E-W compression progressively evolving into an early-D3S transpression and then into a late-D3S NNW-SSE transtension and D4S is a NE-SW compression. Stable isotope analyses of veins and host rock indicate that these veins formed from upwardly migrating, externally derived fluids. Its crystals reach size to 2 mm. Gold mineralization within the Passa Trs Granite is constituted by huge quartz veins with sulfides, variable quantities of fluorite and carbonates, forming orebodies with different internal textures, including massive, banded, sheared and brecciated. We present a quantitative analysis of the electron transfer between single gold nanorods and monolayer graphene under no electrical bias. Bending of the rock bridges and incipient vein rotation indicate that veining occurred near the brittle-ductile transition. Optical processing furnace with quartz muffle and diffuser plate. Initially heat loss from the vapor is high resulting in the formation of acid condensate permeating through the wallrock. Quartz concentration is the only significant explanatory variable of the silicosis severity with a regression coefficient of +0.41 (p < 0.001). Prestea) to giant (e.g. Under these conditions, natural quartz proved to be very weak and to readily undergo plastic deformation, a phenomenon that became known as "hydrolytic weakening". The anastomosis decompressed the mesenteric venous system, so we then ligated the SMV. Silberman, Miles L.; Csejtey, Bela; Smith, James G.; Lanphere, Marvin A.; Wilson, Frederic H. The now largely abandoned Willow Creek mining district, southern Talkeetna Mountains, Alaska, produced nearly $18,000,000 in gold and minor silver between 1909 and the early 1950's. A hypabyssal, mainly rhyolitic to rhyodacitic, and commonly porphyritic, 8- ?? is highly radioactive. However, the impact of vein traits on plant performance has not yet been tested in a model system such as Arabidopsis thaliana. $87.68. 6 Fig. 880.6980 Section 880.6980 Food and Drugs FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN SERVICES (CONTINUED) MEDICAL 880.6980 Vein stabilizer. We present the firsts K-Ar ages for hydrothermal illite/smectite mixed layers (I/SR1, 60% illite layers) and illite that constrain the age of the ore deposit (8.5-6.7 0.2 Ma). Both formed in active andesite-dacite volcanic terranes. This search went on through a 500 MPa liquid-medium machine at temperatures up to 300C, then with a gas-medium machine for temperatures up to 800C, and finally with a solid-medium machine for higher pressures and temperatures. SHRIMP and 40Ar/39Ar age constraints for timing of plutonism and mineralization in the Boulder batholith, Lund, K.D. The sulfide mineral assemblage is dominated by arsenopyrite, pyrite, and, typically younger, stibnite; gold is refractory within the arsenopyrite. Quartz from both HT1 and HT2 veins, Vein matching using artificial neural network in vein authentication systems. High-salinity, halite and/or sylvite-bearing, liquid-rich, and vapour-dominated, CO2-bearing fluid inclusions are assumed to be of magmatic origin. Quartz and carbonate veins less than 5 mm thick are boudined, whereas thick quartz veins ( 1.2 m) have disrupted and brecciated margins; mylonitized country rock envelops quartz-vein fragments. Particles, both angular and fibrous, were extracted from lung parenchyma by a bleach digestion method, mounted on copper microscopic grids by a carbon replica technique, and analyzed by transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS). Zoned grains have more variable Ag contents; grain cores have means of approximately 10% or 23% Ag, with Ag-poor zones of approximately 3.7% Ag along internal discontinuities and/or outer rims. Vein micas and carbonate-quartz-mica assemblages that formed by hydrothermal metasomatism of ultramafic wall rocks in the Alleghany, Grass Valley, Washington, and Mother Lode districts yield concordant K-Ar and Rb-Sr ages. The ERACE study demonstrated that a low incidence of ACE can be achieved with a platinum multi-electrode RF catheter (PVAC) combined with procedural manoeuvres to reduce emboli. Rock samples from quartz veins show maximum values of Au (17100 ppb), Pb (21100 ppm), Ag (9.43ppm), Cu (611ppm) and Zn (333 ppm). Self-taught axillary vein access without venography for pacemaker implantation: prospective randomized comparison with the cephalic vein access. This premise is demonstrated for high-grade metamorphism on the island of Naxos, Greece, where quartz-kyanite oxygen isotope thermometry from veins in high-grade metamorphic pelites gives temperatures of 635-690 C. Stream-sediment and panned-concentrate samples from the northwestern part of the roadless area, reveal anomalous values in a number of elements. In this study the inherent nonlinearity of the metal is measured directly (rather than deduced from a suitable EMT) using a very thin gold film. A vein stabilizer is a device consisting of a flat piece 21 Food and Drugs 8 2010-04-01 2010-04-01 false Vein stabilizer. The LSPR was found to be blue shifted up to 10nm with annealing temperature varying from 400 C to 800 C. Chemical analyses by EMPA indicated that they are constituted by pure gold with Ag and Hg as trace elements. Gold anomalies are more widespread, and extend to shallower depths, but are less coherent. Deposits in metamorphosed sedimentary rocks, especially carbonate-rich rocks and carbonate iron-formation, yielded the great bulk of the gold. The Miocene geological evolution of Bucium Rodu and Frasin magmatic-hydrothermal system took place in closely relationships with tectonic, magmatic and metallogenetic activity from Bucium-Rosia Montana-Baia de Aries district in general, and adjacent areas, in special. $849 (Homestead) pic hide this posting restore restore this posting. The Tom's Gully deposit consists of a shallowly S-dipping quartz reef in graphitic shale and siltstone within the thermal aureole of the post-tectonic (1831 6 Ma) Mt Bundey pluton. ; Aleinikoff, John N.; Kunk, Michael J.; Unruh, Dan M.; Zeihen, G.D.; Hodges, W.C.; du Bray, Edward A.; O'Neill, J. Michael. The collisional Nabitah orogeny represents the suturing of the two terranes. The alignments among the aperture masks are realized by the ABM Mask Aligner System. Harvesting an internal jugular vein graft required extra time and using a synthetic graft posed a risk of graft thrombosis or infection. Adrenal venous sampling (AVS) is a gold standard for subtype classification of primary aldosteronism (PA). We can infer by analogy to silica that this also implies that ore-forming solutions contained elevated (supersaturated) dissolved concentrations of both gold and silver that formed colloidal particles under disequilibrium (often chaotic) conditions. The copper- and cobalt-bearing veins of part of the Quartzburg district are in fracture zones trending about N. 70 degrees E. in folded Permian (?) Gold deposits are localized within and surrounding a Jurassic (159 Ma) quartz monzonite porphyry pluton and dike complex that intrudes Cambrian to Mississippian carbonate and clastic rocks. Amid rising prices and economic uncertaintyas well as deep partisan divisions over social and political issuesCalifornians are processing a great deal of information to help them choose state constitutional The measured carbonate 13C values correspond to ore fluids with 13CCO2 = -6.7 0.7 PDB. Further fossil and recent SSZ like the Mirdita ophiolite, Albania, the South-Anatolian ophiolites, Turkey, and the Izu-Bonin fore arc, respectively, reveal similar volcanic sequences. "Sinc Fluid inclusion studies (microthermometry and Raman) were undertaken in order to distinguish fluids contemporaneous with the barren quartz from those contemporaneous with the ore-bearing quartz (QIII). Phlegmasia cerulea dolens (PCD) is a rare condition resulting from venous occlusion that impairs arterial flow. The quartz crystal microbalance is a physical technique that detects changes in the resonance frequency of an electrically driven quartz crystal with changes in mass. About Vintage Allen Ethan Value Furniture . The light induced cytosolic delivery of calcein from the gold nanoparticle containing liposomes was shown, whereas no cytosolic release was seen without light induction or without gold nanoparticles in the liposomes. ?

Packaging technology of the micromachined quartz tuning fork gyroscopes by vacuum welding has been experimentally studied. Prop 30 is supported by a coalition including CalFire Firefighters, the American Lung Association, environmental organizations, electrical workers and businesses that want to improve Californias air quality by fighting and preventing wildfires and reducing air pollution from vehicles. The Jardine district is one of only three Archean lode gold districts in the United States that have reserves of greater than 300,000 ounces of gold. The third hydrothermal stage introduced the bulk of the mineralization and affected the volcanic rocks, the diatremes, and the Chim Formation. X-ray photoelectron spectroscopy (XPS) was employed to characterize the amylose brushes before and after the adsorption of fatty acids. (Contrib Mineral Petrol 160:743-759, 2010) and the average Zr-in-rutile isopleth calculated from the calibration of Tomkins et al. An homologous series of isoprenoid hydrocarbons ranging from at least C14 to C20 is present in unusually high concentrations. Finally, we evaluated data reported during the past decade and draw relevant and useful conclusions from this analysis. The first three episodes are interpreted to have formed at the same time and probably from fluids of similar composition: a 290-230 C fluid dominated by meteoric and volcanic waters (-3 to -0 18Owater), with <3 % NaCl equivalent salinity and with a magmatic source of sulfur (-1 to -2 34Swater). When one adrenal vein fails to be cannulated, results from the contralateral vein can be useful in conjunction with imaging and clinical findings to suggest further management. The electrochemical results showed that the ET process is complex, being chiefly diffusional with steps depending on the orientation of the pyridine or phenyl tail group of the modifiers. Mrquez-Zavala, M. Florencia; Heinrich, Christoph A. Alto de la Blenda is a 6.6-Ma intermediate-sulphidation epithermal vein system in the Faralln Negro Volcanic Complex, which also hosts the 7.1-Ma porphyry-Cu-Au deposit of Bajo de la Alumbrera. They also corroborate a system of northwesterly and northeasterly conjugate structures that probably are fundamental to the structural framework of the Toquima Range. Truly fibrous calcite veins occur mainly in carbonaceous shales and are characterised by high length:width ratios of their fibres (>10). Modeling involved calculation of rock-buffered fluid compositions over the temperature interval 100-500 C, and reaction-path simulations where a rock-buffered high-temperature fluid reacts with fresh host-rocks at temperatures of 400, 300 and 200 C. Quartz sample containers lower the (17)O values of designer sulfate reference materials and USGS35 nitrate by 15% relative to gold or silver sample containers for quantities of 2-10 mol O(2). PART I.
