碳质陆源火山岩层中常产有大型金矿床,目前对研究黑色页岩层的含金性给予很大的注意。本文研究了西伯刊亚地台元古代盆地中金矿田碳质陆源岩石内金的分布和含铜的碳质陆原建造内岩石的金分布,还收集了地球上其他地区有关碳质生成物的本底含金性。在此基础上,发现具有不同矿化黑色页岩建造的地球化学差异,以及地壳不同构造单元内同类型碳质岩石中金含量的时代变异性。
Large-scale gold deposits are often found in carbonaceous terrigenous volcanic rocks. At present, great attention is paid to the gold-bearing properties of black shale formations. In this paper, we study the distribution of gold in terrestrial rocks and the gold distribution in rocks of copper-bearing carbonaceous terrestrial rocks in the Mesozoic Archean, Archean, Archean, Tibet Plateau. We also collected the distributions of carbonaceous products in other parts of the earth Background gold content. On this basis, we found that there are geochemical differences between the different shale mineralized shale deposits and the temporal variability of the gold content of the same type of carbonaceous rocks in different structural units in the crust.
