WebDec 1, 2015 · Introduction. Argentina is known for several world-class gold deposits such as those in the El Indio–Pascua gold district which hosts the Veladero and Pascua-Lama high sulfidation epithermal gold deposits (only the Pascua deposit is located in Argentina, with the Lama deposit being on the Chilean side of the border), and the Deseado Massif gold … WebCharacteristics of porphyry copper deposits include: The orebodies are associated with multiple intrusions and dikes of diorite to quartz monzonite composition with...

WebApr 1, 2024 · Abstract. Intermediate sulfidation (IS) veins is one of the subtypes of epithermal deposits formed in subduction-related arc settings or post-collisional orogenic belts. The economic and scientific significance of IS deposits has been highlighting importance in Ag-Au-Pb-Zn exploration and study of porphyry-epithermal systems. Webthe porphyry and epithermal deposits in northern Peru are closer in location and age. The major high-sulfidation deposits, from north to south, are Yanacocha (a series of deposits formed at 13.6 to 8.2 Ma), Lagunas Norte (~17 Ma), Calaorco (La Arena; 25.8 Ma) and Pierina (14.5 Ma), with the intermediate (to high-) sulfidation veins of great white feeding chart

WebPorphyry systems and epithermal deposits 863 It must be noted that these assessment results do not in any way imply the potential for discovery of any of the estimated undiscovered resources. WebEpithermal gold (± Cu & Ag) deposits form at shallower crustal levels than porphyry Cu-Au systems, and are primarily distinguished as low and high sulphidation using criteria of varying gangue and ore mineralogy, deposited by the interaction of different ore fluids with host rocks and groundwaters. Low sulphidation deposits are in turn further divided … Webin the development of epithermal-porphyry deposits, with profound implications on mineral exploration of these vein deposits (Corbett, 2008; Leach and Corbett 2008).
