贵州沿河杨家坝重晶石矿地质特征及成矿模式浅析

THE GEOLOGICAL FEATURE AND PRELIMINARY ANALYSIS OF YANGJIABA BARITE DEPOSIT IN YANHE,GUIZHOU

贵州黔东北地区中低温热液型重晶石矿广泛发育,尤其是沿河县境内矿床分布众多,重晶石中伴生有大量的萤石矿。沿河县杨家坝重晶石矿区矿体较多、规模较大、矿石品位较高。通过对杨家坝矿区资料整理分析、研究,大致梳理了矿床特征,并对矿床成因及成矿模式进行了初步总结,对该类矿床的后续研究工作提供一定启示。

The middle-low T hydrothermal barite deposit is widely developed in NE Guizhou area,there are many barite deposits specially in Yanhe county,wiih a lot amount fluorite and barite paragenesis.In Yangjiaba barite orefield of Yanhe,there are many orebody,in large scale,with high ore grade.According to the arrangement,analysis and study of Yangjiaba orefield data,we have roughly sorted out the deposit characteristics,preliminarily summing up the deposit genesis and metallogenesis model,provided some help for the further study.
