摘要
在成因上,八卦庙金矿床是一受封闭构造环境控制的NWW向脆-韧性剪切带与NE向节理密集带相交控制的特大型金矿床,并与二元热力事件密切相关的热水沉积-岩浆再造型金矿。本文详细从沉积环境、构造、成矿热液和岩浆活动等几方面作了综述,并结合野外工作实践,总结了"八卦庙式"金矿的成因类型和找矿标志,提出金矿预测的原则和靶区。
The Baguamiao gold deposit is a giant gold deposit controlled by intersection of NWW trend brittle-ductile shear belt controlled by closed strcture environment and NE trend joint dense belt tectonic environment,and is closely related to the dual thermal events of hot water sedimentation- magmatic remolding gold deposit. ed with the field practice,the work in detail is summarized from the sedimentary environment structure,metallogenic hydrothermal and magmatic activity and so on,and the genetic types and prospecting marks,gold prediction principle and target of Baguamiao type gold deposits are put forward.
