摘要 四川省平武松潘地区危关组及新都桥组黑色炭质岩系是本区重要的含金层位,也是本区金矿的间接找矿标志。其成矿经历了四个不同的构造成矿演化阶段,分别为发生在晚印支造山期前、晚三叠世中-晚期、燕山期、古近纪末等不同时期的构造运动,各时期构造运动为金矿的形成提供了物质来源、构造通道等不同要素。 The Sichuan Pingwu Songpan area Wei Guan formation and the xindaqiao group black Carboniferous rock series are the important gold bearing strata in this area, and are also the indirect prospecting criteria for the gold deposits in this area. The mineralization has undergone four different stages of tectonic mineralization, which occur in the different periods of the late Indosinian orogenic period, the late three fold middle period, the Yanshan period and the end of the Paleogene, and the tectonic movement of each period provides the different elements of the material source and structural channel for the formation of gold deposits.
