最近几年来,人们对于含有重要矿产资源的前寒武纪沉积地层非常重视,尤其是对于含有世界上储量丰富的金、铀和其它矿产资源的含矿砾岩建造非常重视。在前寒武纪砾岩中找到了世界著名的金刚石砂矿。但对其形成规律和赋存仍很少文献报导。作者曾到非洲、南美和印度搜集了有关前寒武纪地质和金刚石含矿性的资料,表明金刚石矿化是位于地壳大的构造带中,其成分和陆缘结构及含金刚石的岩浆建造具典型
In recent years, great attention has been paid to Precambrian sedimentary formations containing important mineral resources, especially for the construction of ore-bearing conglomerates containing the world’s abundant gold, uranium and other mineral resources. Found in the precambrian conglomerate world famous diamond ore. However, there is still little literature on its formation and occurrence. The authors have collected data on the Precambrian geology and diamond ore-bearing in Africa, South America and India, indicating that diamond mineralization is located in a large crustal tectonic belt and its composition and marginal structure and diamond-bearing magma typical
