鲁西车往峪隐爆角砾岩群特征及其控矿意义

Characteristics and Ore-prospecting Significance of Chewangyu Cryptoexplosive Breccia in West Shandong

摘要:

通过对车往峪角砾岩群中岩体的分布格局 ,岩石特征、矿化蚀变及构造控制因素的分析 ,指出该角砾岩群由隐爆作用形成。隐爆角砾岩群与磁异常及Au ,Ag ,Cu元素组合异常套合较好 ,基岩化探也显示出较高的As,Sb元素异常。故其成矿前景较好 ,深部可能存在隐伏岩 (矿 )体

Abstract:

Through comprehensive analysis of controlling structures, distribution, characteristics of intrusives and rocks, mineralization, alteration, geophysical and geochemical abnormality, Chewangyu cryptoexplosive breccia is considered as forming by cryptoexplosion. Meanwhile, cryptoexplosive breccia is in better conformity with magnetic abnormality, combination abnormality of Au, Ag and Cu which obtained from geochemical survey, and higher As and Sb abnormality from rock geological survey. According to the infor...
