Pyrite is one of the most common minerals in many precious and base metal hydrothermal
ore deposits and is an important host to a range of trace elements including Au and Co and …

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 …

Porphyry Cu systems host some of the most widely distributed mineralization types at
convergent plate boundaries, including porphyry deposits centered on intrusions; skarn …

Formation of hydrothermal ore deposits requires a fluid with the capability to transport and
deposit metals, and the sources and physical and chemical characteristics of these …

Advanced argillic minerals, as defined, include alunite and anhydrite, aluminosilicates
(kaolinite, halloysite, dickite, pyrophyllite, andalusite, zunyite, and topaz), and diaspore. One …

Abstract Porphyry Cu±Mo±Au and some epithermal Au deposits are formed from
hydrothermal fluids exsolved from cooling, water-rich, calc-alkaline magmas emplaced in …

Use of the concept of “sulfidation state,” in parallel with oxidation state, in the study of ore
deposits finds its beginnings with the studies of Reno Sales and Charles Meyer at Butte …

Giant ore deposits contain anomalously large quantities of metal and are priority targets for
mineral exploration companies. It is debated whether these giant deposits have a unique …

Porphyry deposits are the world's most important source of Cu and Mo, and are major
sources of Au, Ag, and Sn; significant byproduct metals include Re, W, In, Pt, Pd, and Se …

Metal-rich fluids that circulate in magmatic-hydrothermal environments form a wide array of
economically significant ore deposits. Unravelling the origins and evolution of these fluids is …
