摘要
阿比金金成矿带产于上泥盆统卡希翁组及江孜尔库都克组中基性火山岩带中。岩石遭受强烈挤压，具极强片理化、糜棱岩化，形成千枚岩及糜棱岩。石英细脉及石英网脉发育。特别是与主构造线成锐角的细石英脉、网脉发育，具一定含矿性。该挤压蚀变带的含矿性及延续性较好。围岩蚀变主要有硅化、黄铁绢英岩化、褐铁矿化、赭石化、碳酸盐化等。为典型破碎蚀变岩型金矿产区。
In the Abijin gold belt which is located within the Kaxiweng Formation and Jiangzerhuduke Formation mediate basic volcanic rocks of upper Dovinian, host rocks were extensively compressed and deformed into phyllite and mylonite. The ore bearing quartz veins and networks, espeically those intersected with altered compressed belt show considerable mineralization and extension. The alteration is characterized by silicification, beresitization, limonitization, ocheritization and carbonitization. It belongs to one types of gold deposit hosted in altered compressed structure belts.
