Pyrite And Gold In Quartz And Rokes

Jan 01 1999 All rocks have been subjected to middle greenschist facies regional metamorphism. Most gold mined occurs in the form of inclusions in vein and wall-rock pyrite in steeply dipping highly strained tholeiitic basalt and carbonaceous shale; however considerable free gold was also mined from quartz veins located mainly within brittle altered basalt.

May 12 2011 The Mesozoic Yangzhaiyu lode gold deposit is situated in the southern edge of the North China craton. Gold mineralization is hosted in Archean amphibolite facies metamorphic rocks and consists mainly of auriferous quartz veins. Pyrite is the predominant sulfide mineral with minor amounts of chalcopyrite sphalerite and galena. Based on morphology and paragenesis there are three

Geochemistry Of Hydrothermal Gold Deposits A Review

Jul 01 2011 A late-stage mineral assemblage consisting of quartz–native gold–amesite–sericite–calcite–dolomite–pyrite–apatite appears to be related to the high to medium temperature alteration of wall-rocks. The Re–Os age of gold-bearing arsenopyrite ∼290 Ma overlaps regional magmatism in the Muruntau Morelli et al. 2007.
