摘要
老王寨金矿区在构造上是哀牢山韧性剪切带的一部分,为以韧性剪切变质岩加坚硬原岩块体组成的变形-变质地质体,发育有各种韧性变形特征和以糜棱岩、千糜岩为主的岩石组合。金矿化在空间上和形成机制上明显受控于韧性剪切带,老王寨金矿床属含金剪切带类型。
Structurally, being part of the ductile shear zone of the Ailao Mountain, the Laowangzhai gold ore area is a deformed-metamorphosed geological body composed of the ductile shear metamorphite and hard protolith masses. It has various ductile deformed features and the rock association dominated by my-lonite and phyllonite. The gold mineralizations were obviously controlled by the ductile shear zone in space and formed mechanism. The Laowangzhai gold deposit belongs to the type of auriferous shear zone.
