开发矿产资源方面的成就,现在比以往任何时候都更加依赖于对地球化学异常实质的认识,地化异常表现为金属的局部富集,即所谓的金属矿床。从这个公认的原则中可以看出,必须解决三个基本的问题:金属及其伴生元素是从哪里来的;它们是怎样、通过什么样的途径迁移到地壳中来的;在什么地方、什么条件下它们停止了迁移,从而留下了有价值的东西。换言之,需要重视一般成矿作用的三个部分:成矿物 Achievements in the development of mineral resources are now more dependent than ever before on an understanding of the true nature of geochemical anomalies, which are characterized by the local enrichment of metals, the so-called metal deposits. From this generally accepted principle, one can see that three fundamental questions have to be solved: where the metals and their associated elements come from; how and by what ways they migrate into the earth’s crust; and where and what Under the conditions that they stopped the migration, leaving valuable things. In other words, three parts of the general mineralization need to be emphasized: mineralization
