中文摘要:
      本文以贵州六枝特区平桥萤石(锂)矿重点矿产资源大精查项目为基础,结合邻区大厂锑矿的硅化蚀变体特征进行对比研究,对成矿规律进行了探讨和总结。二者在地理空间、大地构造位置、成矿区带均为邻近关系。均位于褶皱隆起区内,且受层间构造控制影响。据重力解释成果推测二者深部均有中酸性岩浆岩隐伏。其硅化蚀变岩均位于碳酸盐岩/粘土岩界面之间,与上、下地层均为不整合接触关系。其矿化组合体现与硅化等系列矿化蚀变密切相关的中低温矿物组合特征。在此基础上归纳总结了其 “三位一体”成矿规律,认为二者均以深部隐伏的中酸性岩体为成矿地质体;以系列的碳酸盐岩/粘土岩界面为成矿结构面,并形成地球化学、矿物组合等系列的成矿作用特征标志,“三位一体”成矿规律的总结为该区域远成低温热液型矿床的深部勘查提供了有益探索。
英文摘要:
      In this paper,based on the project of the exact survey on the key mineral resources of the Pingqiao fluorite(lithium)deposit in Liuzhi Special Zone,Guizhou,combined with the characteristics of the silicified and altered variants of the Dachang antimony deposit in the neighboring area,a comparative study is carried out to explore and summarize the metallogenic regularityThe two are adjacent in terms of geographic space,tectonic location,and metallogenic zone;their silicified and altered rocks are located between the carbonate/claystone interface,and are in unconformity contact with the upper and lower strata;both of them are located in the fold-uplift area,controlled and affected by the interlayer structure;both have intermediate-acid magmatic rocks concealed in the deep part according to the results of gravity interpretation;the mineralization combinations of the two are very similar,which shows the medium and low temperature mineral assemblage characteristics that are closely related to the series of mineralization and alteration such as silicification;on this basis,the "trinity" metallogenic regularity of the two is summarized,and it is believed that the deeply concealed intermediate-acid rock mass is the metallogenic geological body;based on the series of carbonate rock/clay-rock interface is a metallogenic structure surface,and a series of metallogenesis characteristic indications such as geochemistry and mineral assemblage are formedThe summary of the "trinity" metallogenic regularity provides a useful exploration for the deep exploration of telethermal low-temperature deposits in this area
