摘要
通过对鹰嘴山金矿容矿围岩的研究及加里东期超基性岩含金性的评价,认为鹰嘴山金矿的金主要来自超基性岩,而且超基性岩浆的侵入为黒茨沟组火山岩中微量金的加剧活化提供了热力条件。同时研究了断裂控矿性质、矿床地球化学特征认为,鹰嘴山金矿是一个与超基性有关的中低温热液型金矿床,提出了成矿模式。
The authors support that the gold of Yingzuishan gold deposit was mainly originated from ultra-mafic rocks,and the invasion of the ultramafic rocks provided the heat condition for the action of trace gold in igneous rocks of Heicigou Formation.The studies of ore-control structures and geochemical features show that Yingzushan gold deposit is a meso-eqithermal deposit.
