Mineralization occurs along three main vein systems trending dominantly northwest–southeast: the central Veta Madre, the La Luz system to the northwest, and the Sierra system to the east. Book January with 98 Reads How we measure 'reads' A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure.
Since alteration and mineralization at both Chinkuashih and El Indio were formed from a vapor phase (see Section ) to depths below the paleosurface of about m and stable isotope data indicate limited, if any, incursion of groundwater, the fluid pressure in the developing vein system was evidently greater than that due to an external Cited by: While the total range in T h for porphyry copper systems is similar to that observed for epithermal deposits, a larger proportion of FIAs show a range of >10°C.
Analysis of the data for porphyry deposits shows that 11 out of FIAs show identical T h for all fluid inclusions in the assemblage (range = 0°C), and 24 out of FIAs show a Cited by: Giggenbach's preliminary observations on the magmatic volatile contributions to systems of the Taupo Volcanic Zone, the site of minor low-sulfidation epithermal mineralization (Barker, ), may have profound significance for the origin of epithermal precious metal deposits, in particular those occupying the spectrum of bimodal rift settings.

Calderas are generally larger than volcanic craters and form by subsidence, whereas craters form by explosive excavation and ejection, and buildup of ejecta around a as may be symmetrical or asymmetrical, but they are distinct from open-sided sector-collapse scarps (horseshoe-shaped valleys) that form by outward-directed sector-collapse landslides down flanks of unstable volcanoes.

Geodynamic context and mineral alteration patterns are closely similar to those of Maria Josefa gold mine at SE of Spain which exhibit a volcanic-hosted epithermal ore deposit in a similar vein system, within rhyolitic ignimbrites, altered to an argillic assemblage (illite-sericite abundant and subordinate kaolinite) that grades outwards into.

Most high-sulfidation deposits are generated in calc-alkaline andesitic-dacitic arcs characterized by near- neutral stress states or mild extension, although a few major deposits also occur in compressive arcs charac- terized by the suppression of volcanic activity.5/5(2).

Veins containing skutterudite, rammelsbergite, nickelite, gersdorfﬁte and chalcopyrite are bound to a fault system intersecting Precambrian rocks in the contact zone between serpentine and other rock types: (1) veins in the serpentinite, (2) veins in the contact between serpentinite and other rocks, (3) mineralized faults.

ICKES, Secretary GEOLOGICAL SURVEY W. MENDENHALL, Director Bulletin BIBLIOGRAPHY OF NORTH AMERICAN GEOLOGY AND BY. Creede Mining District The Creede Mining District is an archetypical example of a style of epithermal (near-surface hydrothermal) mineralization produced by near-neutral ore fluids and characterized by sericite ± adularia wall-rock alteration and the presence of adularia in the vein filling.
