The Cause and Prospecting Significance of Ring Structures from Zhengxiangbaiqi in Inner Mongolia
摘要
Abstract
The ring structure as an indicator has great significance and value for prospecting .On the base of satellite remote sensing images and geophysical and geochemical anomalies , the annular configuration and prospecting information in Zhengxiangbaiqi are analyzed in depth .The biggest circular H5 is about 30 km in diameter .Edge regional faults have different directions .Mineral re-source is located in fracture interchange , which is also related to volcanic and magmatic intrusion . Regional geological survey ( 1:50000 ) shows that Zhengxiangbaiqi ring structure is the result of Late Permian magmatism and its deep regional faults joint action , and caused by contact alteration of the intrusive rocks and wall rock .Small ring structure is a good metallogenic area , and the edge area of large ring structure is a prospective area of ore prospecting .关键词
