| 摘 要： | 康古尔韧性剪切带是一个复杂而强烈的构造变形带，其特征表现为４个变形期次。由于韧性剪切──区域动力作用，使变质程度明显高于剪切带两侧的区域埋深变质，变质特征表现在葡萄石－绿纤石相经韧性变形作用后，形成一套低绿片岩相变质地层，体现出前进变质作用的特点──矿物普遍细粒化，并发生动态重结晶，这套低绿片岩相变质地层，为金的富集成矿提供了可靠的矿源层。

| Abstract: | The ductile shear zone in Kangurtag went through 4-phase complicated and intensive structural deformation.Ductile shearing-regional dynamic metamorphism of the shear zone is obviously higher than regional burial metamorphism of the two sides.The metamorphism is characterized by a sequence of low greenschist phase formed by ductile shearing of ciltonite-chlorastrolite phase.It is shown as progress metamorphism,that is,the minerals mostly get fine-grained and accept dynamic recrystallization.The low-greenschist phase metamorphism supplies a reliable ore source bed for the concentration of gold. |
