本文将桐柏-商城地区金矿床划分为三种类型,即产于含碳泥质变质岩系中的岩浆热液型金矿床、产于花岗岩中的岩浆热液型金矿床和剪切带型主矿床,并分别论述了各类型主矿床特征及成矿条件。指出含碳泥质陆屑碎屑-碳酸盐岩夹火山沉积合金建造是区内主要含金建造,它为金矿成矿提供物质来源,金矿找矿工作的重点应放在这套合金建造的分布地段。
In this paper, the gold deposits in the Tongbai-Shangcheng area are divided into three types, that is, the magmatic hydrothermal gold deposits in the carbonaceous shaly metamorphic rocks, the magmatic hydrothermal gold deposits and the shear zone Main deposit, and discussed the characteristics of each type of main deposit and metallogenic conditions. It is pointed out that the construction of carbonaceous muddy continental litter-carbonate volcanic sedimentary alloy is the main gold-bearing construction in the area, which provides the material source for the gold mineralization. The focus of the gold ore prospecting work should be put on this alloy Construction of the distribution lot.
