摘要
薄刀岭银金矿是典型的韧、脆性剪切带型矿床,主要成矿作用为燕山晚期,石英脉残余含矿热液与深对流循环萃取的成矿物质因介质条件改变而沉积成矿。成矿物质来源于薄刀岭大石英脉和高背景地层龟山岩组。其成矿作用受韧性剪切断裂控制作用明显。
The Bodaoling Ag-Au deposit is a typical ductile- and brittle-shearing type one. Main ore-formation occurred in the late Yanshanian epoch. Ore-forming material was derived from large quartz veins and the Guishanyan Formation as the source bed in Bodaoling. The ore-formation was obviously controlled by ductile shearing fault.
