重视元古界的找矿为什么我想谈这个问题呢?因为元古界从时代来看从6亿年一直到25亿年,时间很长,有十多亿年,将近20亿年.这在地球发展历史上占的份量是很大的,按理说应当有不少矿产.但是从我国现在的情况来看,太古代的矿产找到的比较多,古生代、中生代的矿产也比较多,元古代则是一个薄弱环节.太古界有大量的鞍山式铁矿,还有不少金矿及其他矿产.对于太古界的认识,一般说来还比较深化.古生代地层中所包含的矿产,有一大套有色金属,象华南的汞、锑、铅、锌,大量的都在古生代地层中.中生代有着大量与花岗岩、火山岩有
Emphasis on the prospecting of the Proterozoic Why I would like to talk about this issue? Because the Proterozoic from the era of view from 600 million years to 2.5 billion years, a long time, there are billions of years, nearly 2 billion years. The history of the Earth’s development occupies a large part of it, and it stands to reason that there should be a lot of minerals, but from the current situation in our country, there are more minerals found in the Archean, more minerals in the Paleozoic and Mesozoic, and Proterozoic Is a weak link in the world. There are a large number of Anshan-style iron ore in the Archean world and many gold and other minerals. The understanding of the Arctic, in general, is still relatively deep. The minerals contained in the Paleozoic strata have a large set of colored Metals, such as mercury, antimony, lead and zinc in southern China, are abundant in the Paleozoic strata, and Mesozoic strata have large deposits of granites and volcanic rocks
