广西高龙穹窿构造蚀变体特征与找矿潜力

Characteristics of structural altered body and prospecting potential in Gaolong Dome,Guangxi

高龙穹窿分布多个矿体,其周边的环状断裂形成矿体。随着多层次构造蚀变体的研究理论在黔西南地区金找矿中取得重大成果,认为热液在背斜(穹窿)核部附近的不整合界面或者能干性差异较大的岩层面易形成多层次构造蚀变体。通过在高龙穹窿首次进行构造蚀变体特征研究,对矿体特征、分布状况、环状断裂进行了重新认识,最终对找矿潜力进行了分析,该成果可为高龙穹窿进一步找矿提供依据。

Multiple ore bodies are distributed in the Gaolong Dome,and the surrounding circular fractures form the ore bodies.As the research theory of multi-level structural altered body has made significant achievements in gold prospecting in southwest Guizhou,it is believed that the hydrothermal fluid is likely to form a multi-level structural altered body on the unconformity surface near the core of the anticline(dome)or the rock surface with a large variance in dehydratability.Through the first study on the characteristics of the structural altered body in the Gaolong Dome,the characteristics and distribution of the ore body,as well as the circular fractures,were re-recognized.Finally,the potential for ore prospecting was analyzed,which can provide a basis for further prospecting in the Gaolong Dome.
