摘要
通过对黔东南地区下江群清水江组地层111件岩石样品进行岩矿鉴定、统计分析,得出该组地层为一套含凝灰物质的低绿片岩相区域变质岩,对其岩性、矿物成分、结构构造等特征有了系统的认识,为后期研究该组地层、原岩恢复及其与金矿关系等工作提供参考。
Through the rock-mineral determination and statistical analysis of 111 rock samples of Xiajiang Group Qingshuijiang Formation in Qiandongnan area,it was known that this formation is a set of low green schist facies regional metamorphic rock which includes tuff material,and a systematic cognition was gained on its lithology,mineral composition,structure,etc,which provides reference for the later study on this formation layer,protolith reconstruction,and its relation with gold ore and so on.
