摘要
卡林型金矿是一种主要产于碳酸盐岩—碎屑岩建造中的微细粒浸染型金矿床,以储量大、品位低、金粒度极细为特点,主要分布于美国和中国,区域地质、成矿条件、控矿因素、矿化特征具有明显的可类比性。卡林型金矿区域成矿模式可概括为:金、汞、砷、锑等成矿元素大规模超常聚集,矿质运移—传输,矿床(矿体)的定位等三大系统(阶段)。文中亦对国内外卡林型金矿的成矿系列、成矿模式作对比研究。
The Carlintype gold deposit is a kind of fine disseminated gold deposit and it lies mainly in the carbonate rock and clastic rock formation. This kind of gold deposit is characterized by large reserves, low grade and very fine granularity. They are distributed mostly in America and China, and obviously comparable on the regional geology, metallogenetic condition, orecontrolling factor and ore features. The regional metallogenetic model of Carlintype gold deposit includes 3 aspects, ie the large scale concentration of metallogenetic elements Au, Hg, As and Sb; metallogenetic material movement and orebody emplacement. A comparison study on the metallogenetic series and metallogenetic model of Carlintype gold deposit is put forward in this paper.
