灵宝四范沟矿区含金石英脉成矿阶段及研究意义

Metallogenic stage and research significance of gold-bearing quartz vein in Lingbao Shivan mining area

小秦岭金矿田主要位于华北地台南缘陕西潼关、河南灵宝一带,秦岭造山带为主要成矿构造带;石英脉型金矿为主要成矿类型,特别是第Ⅱ石英—黄铁矿阶段和第Ⅲ石英—多金属硫化物阶段为金矿主要成矿阶段,在小秦岭地区找矿具有指导意义。

The small Qinling Gold fields are mainly located at Tongguan, Henan Lingbao area in the Tainan margin of north China, and the Qinling orogenic belt as the main metallogenic tectonic belt;the quartz vein type gold deposit is the main metallogenic type, especially the Ⅱ quartz-pyrite stage and the Ⅲ quartz-polymetallic sulfide phase as the main metallogenic stage of gold deposit, which is instructive in the small qinling region.
