The productive mineralization of the Sheikhdzheili-Zengiboba area is associated with metamorphogenic transformations rocks Urusai, Karauzyak, Kuyanchik, Sheikhdzheili suites, metamorphosed under conditions green schist facies. mineralized zones site are confined to narrow faults in tectonic northeast and northwest directions. main form manifestation gold-bearing small steeply dipping veins, len...

The Xinjiazui gold deposit, a newly discovered is situated in the northwestern margin of Yangtze Block, China. source and genesis mineralization are poorly understood. It urgent to use H–O isotopic composition quartz geochemistry pyrite evaluate origins Au ore-forming fluids this deposit. Three types were identified, including synsedimentary framboidal pyrites (Py0), directional arrangement pre...

Giant Quartz Veins (GQVs) are ubiquitous in different tectonic settings and, besides being often related to hydrothermal ore deposits, also represent large-scale fingerprints of the structural and geochemical history rocks which they hosted. Here we present detailed geological maps interpretations three key areas Eastern Pyrenees where GQVs well exposed. The studied record styles deformation re...

The Luyuangou gold deposit is located in the eastern section of Xiong’ershan Au-Ag polymetallic district (XESPMD) and consists a few gold-bearing veins found EW-striking faults Archean Taihua Mesoproterozoic Xiong’er Groups. deposits contain numerous pyrites thin quartz veins, representing an ideal tool for explaining enigmatic genesis XESPMD. distributions trace elements sulfur isotopes pyrite...
