Mineralogical constraints on the genesis of the Dahu quartz vein-style Au-Mo deposit, Xiaoqinling gold district, China: Implications for phase relationships and physicochemical conditions

The quartz vein-style Dahu Au-Mo deposit, with an average grade of 6.8 g/t for 38 tons Au, and an average grade of 0.24% for 100,000 tons Mo, is situated in the Xiaoqinling region in the northernmost part of Qinling orogen in China. It is characterized by enrichment of native gold, molybdenite, telluride and Bi-sulfosalt. The current understanding of telluride and Bi-sulfosalt mineralization in the Dahu Au-Mo deposit is very poor, and this paper...
