Abstract The Dapingzhang dacite-hosted volcanogenic massive sulfide deposit is located in a late Paleozoic collisional zone, the Sanjiang fold-and-thrust belt, characterized by a collage of Gondwana-derived terranes at the southern margin of the South China (Yangtze) block. This area has experienced repeated Paleozoic and Mesozoic collisional and extensional events, and is overprinted by Himalayan strike-slip and thrust movements. The Dapingzhang orebody is strongly sheared into discontinuous or...

Abstract The area of the Middle–Lower Yangtze River valley, Eastern China, extending from Wuhan (Hubei province) to western Zhenjiang (Jiangsu province), hosts an important belt of Cu–Au–Mo and Fe deposits. There are two styles of mineralization, i.e., skarn/porphyry/stratabound Cu–Au–Mo–(Fe) deposits and magnetite porphyry deposits in several NNE-trending Cretaceous fault-bound volcanic basins. The origin of both deposit systems is much debated. We dated 11 molybdenite samples from five skarn/p...

Black shales of the basal Lower Cambrian Niutitang Formation, southeast China, host a regionally distributed concordant, several centimeter-thick, sulfide layer which displays extreme metal enrichment, i.e., Mo-NiSe-Re-Os-As-Hg-Sb >1,000 times enriched and Ag-Au-Pt-Pd >100 times enriched over bulk continental crust. Mineable portions have about 5.5 wt percent Mo, 3.5 wt percent Ni, and 1 g/t PGE + Au. A six-point 187 Os/ 188 Os versus 187 Re/ 188 Os isochron on molybdenum-nickel ore samples defi...

The ages for pegmatite rare metal and beryl (emerald) deposits, as well as porphyry Mo deposits in the Hercynian Uralide orogen, are not well known. Five molybdenite samples from the Lipovy Log pegmatite Ta–Nb–Mo deposit and 11 molybdenite samples from the Shameika porphyry Mo deposit were selected for Re–Os dating. Both mineral occurrences are spatial-temporally associated with the Adui composite granite pluton, a well-known rare metal-related granite intrusion. A Re–Os isochron age of 262.0±7....
