黔南独山与黔西南晴隆锑矿田成矿流体与物质来源对比研究
|
摘要
贵州锑矿是华南锑成矿带的重要组成部分,目前对区内主要锑矿床的成矿流体与物质来源问题存在较大的争议。因此,在搜集黔南独山锑矿田和黔西南晴隆锑矿田的H、O、S、Pb等同位素数据的基础上,通过对比分析来研究这两个地区成矿流体与物质来源的异同。研究结果表明:黔南独山锑矿田成矿流体来源于大气降水,而黔西南晴隆锑矿田的成矿流体应该是由早期温度较低的盆地流体及部分大气降水和后期的温度较高的深部流体混合而成。黔南独山锑矿田中半坡、蕊然沟矿床辉锑矿较富集34S,硫应主要来自赋矿围岩;巴年、甲拜矿床的辉锑矿较富集32S,硫同位素组成显示了较明显的幔源硫的贡献。黔西南晴隆锑矿田的辉锑矿富集34S,硫来自幔源硫。铅同位素组成指示独山矿田锑应主要来源于围岩地层,次为基底;而晴隆矿田应来源于基底与上地幔。
Antimony ore deposits in Guizhou Province are the important component of the antimony ore belt,South China.At present,ideas are controvertial about the sources of ore-forming fluids and materials in these two antimony ore fields.In this study,we collected H-O-S-Pb isotopic data of the Dushan and Qinglong antimony ore fields.Through detailed comparative analysis,we found the ore-forming fluids in Dushan are originated from meteoric waters,and Qinglong ore field is a mixture of the low-temperature basin fluid,meteoric waters and higher temperature deep fluid.In Dushan ore field,the stibnite of Banpo and Ruirangou deposits are enriched in 34 S,and the composition of S isotope indicates that sulphur comes from wall rocks.However,Banian and Jiabai deposits are enriched in 32 S,and the characteristics of S isotope indicate some mantle sulphur mixed in the ore-forming fluid.Qinglong ore field shows the stibnite enrichment of 34 S,with the composition of S isotope indicating sulphur from the mantle.The composition of Pb isotope indicates the origin of ore-forming materials which have the characteristics of multi-sources.In Dushan ore field,the ore-forming materials are mainly deprived from the host strata,secondarily from basement.But,in Qinglong ore field,the ore-forming materials mainly comes from the basement and the upper mantle.
