PRELIMINARY ANALYSIS ON TECTONIC METALLOGENESIS OF W-SB-Au TYPE GOLD DEPOSITS

PENG Bo; DENG Zhiqiang(Changsha Institute of Geotectonics,Academia Sinica,changsha,410013)(Certral-South Bureau of Uraniun GeologicaI Exploration,Changsha,410011)  
The synthetic study shows that the host-rock layers of the W-Sb-Au type gold deposits were formed during the strongly active stages of the crust evolution; the stages of geosyncline and geodepression. The sa dy-slate rock series containing many calcareous-petitic and tuffaceous substances is the best favorable ore-controlling rocks for the W-Sb-Au type gold tectonogeochemical reactions caused by faulting led gold accumulate and form gold deposits.The tectono-metallogenic evolution followed with the crust evolution made the ore-forming elements, such as gold,enriched to form the gold deposits.
