安徽铜陵天马山硫金矿床物质来源探讨

Study on the origin of materials of Tianmashan sulfur gold deposit in Tongling,Anhui

天马山硫金矿床的矿体分为层状、接触带和穿层矿体。接触带矿体是典型的夕卡岩型。层状和穿层矿体受石炭系黄龙组、船山组地层层位和层间断裂控制。铅、硫同位素组成等资料表明 ,其形成经历了同生沉积和岩浆热液叠加、改造两种性质不同的成矿富集过程。金等金属成矿物质主要来源于岩浆 ,砷主要来源于地层 ,硫来源于地层和岩浆。

The ore bodies of Tian Mahan sulfur gold deposit divided into three types of stratiform, contact zone and through stratiform The contact zone ore bodies are typical sharn ones The stratiform and through stratiform ore bodies are controlled by the stratigraphic horizons and interformational faults of HuangLong, ChuanShan formations of Carboniferous system The data of lead, sulfur isotopes shows that the formation of stratiform and through stratiform ore bodies went through metallogenic concentration process of syngenetic deposition and superposition、reformation of magmatic thermal fluid Gold and other metals mainly came from magma,arsanic mainly came from strata,sulfur came from strata and magma
