摘要
韧性剪切带型金矿按其矿化类型可分为三类:即含金糜棱岩型、含金蚀变碎裂岩型及含金石英咏型。挤压型及伸展型韧性剪切带与金成矿密切,而平移型剪切带对金矿化不利。韧性剪切带变形变质作用及演化阶段是确定金矿化能否形成的重要因素。
There are three types of gold deposit of ductile shear zone type according to its mineralization types, that is, bearing-Au myl onite type and bearing-Au alteration cataclastite type and bearing-Au quartz vein. The ductile shear zones of pressure and extension are ciosely related to gold mineralization. Whereas strike-slip ductile shear zones are unfavourable to gold mineralization. The evolution and deformation and metamorphism of ductile shear zone takes an important role in the formation of gold mineralization.
