摘    要:康古尔金矿床形成于脆韧性—脆性剪切变形构造演化过程中。应用透射电镜超微技术分析水热成矿期石英位错构造、位错密度及差应力值有助于加深认识剪切构造条件下的成矿动力学机制。石英位错构造特征反映成矿期构造变形环境为中温—中低温、高差异应力、高应变速率。成矿期构造差应力演化呈明显的脉动性,这种脉动性所形成的“应力地震泵吸”机制对金矿成矿至关重要。

关 键 词:东天山  康古尔金矿床  石英  位错构造  动力学

Abstract:Kanggur gold deposit was formed in the tectonic evolutional process from brittle ductile to brittle shearing deformation.Dislocation micro structures,dislocation density and differential stress values of quartz from hydrothermal ore forming stages were studied by means of transmission electron microscope(TEM),which is helpful to understand shearing tectonic conditions.Disolcation micro structures shows that ore forming tectonic setting belongs to middle to middle low temprature,high differential stress and high strain rate.Ore forming tectonic differential stress values shows a remarkable pulse evalution.The "Earthquake pump" mechanism caused by the pulse evolution has a significance to gold mineralization
Keywords:Eastern Tianshan  Kanggur gold deposit  quartz  dislocation  microstructures  ore      forming dynamics
