钨锑金型金矿床构造成矿浅析

综合研究表明，Ｗ－Ｓｂ－Ａｕ型金矿床的赋矿层位形成于地壳强烈活动期（地槽期、地洼期）。富含钙泥质，凝灰质的砂板岩系是该类金矿床的有利控矿围岩。层间断层在其成矿过程中有特别重要的作用，断层作用过程中发生的构造地球化学反应导致金的聚集成矿，伴随地壳演化而发生的构造成矿演化促使金等矿化元素富集成矿。

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

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.
