摘要

///The Shuiyindong gold deposit, which occurs in the Longtan Formation of the Upper Permian series, is a super-large, high-grade gold ore deposit. The deposit consists of a number of gold ore bodies which occur in basaltic, siliceous and bioclastic carbonate rocks in the Longtan Formation coal measures. Research on the micro fabrics of rocks and ores indicated that the main gold-carrying mineral is fine-grained pyrite, which possesses regenerated rims, intragrain holes, mold hole fabrics, furring biomineralization structure and mold biomineralization structure.
