山西堡子湾隐爆角砾岩型金矿矿床隐爆机制研究

Cryptoexplosive mechanism of the Baoziwan cryptoexplosive breccia-host gold deposit,Shanxi

隐爆角砾岩型金矿是一种比较重要的金矿床类型,其金矿的矿化强度和矿化范围严格受到岩浆隐爆作用范围和隐爆强度的控制。文章通过对堡子湾金矿的矿化、矿体、角砾岩体的形态、分布、成分等方面的特点进行分析和研究,联系它们之间的共性与差异,建立了该矿床的隐爆机制,认清与金矿化关系密切的隐爆作用过程对于预测矿体范围、指导金矿的勘探具有重要的意义。

Cryptoexplosive breccia-host gold deposit is a more important gold deposit type. Its mineralization intensity and extent are strictly controlled by the intensity and range of magmatie cryptoexplosion. Through analyzing and studying the mineralization, orebodies, shapes, distribution and composition of breccias of the Baoziwan gold deposit, considering the commonness and differences of above mentioned factors, the study has set up a cryptoexplosive mechanism for this deposit. It is very significant to get full understanding of cryptoexplosion that is close related to gold mineralization for predicting orebodies ranges and guiding prospecting for gold deposit.
