地球化学是地质科学中一门新学科,是在本世纪初随生产的需要和近代科学技术的发展而兴起的,至今还在迅速发展着。它的研究领域很广阔,已出现了好些分支学科。这里只介绍一下这门学科的概貌。揭露地球物质的微观世界人们很早就想知道自己居住的地球是由什么物质成分组成的,也很想知道这些物质成分怎样分布,分布量 Geochemistry is a new discipline in the geological sciences. It began at the beginning of this century with the needs of production and the development of modern science and technology. It is still developing rapidly. Its research area is very broad, and there have been many branches. Here is only an overview of the subject. Exposing the microscopic world of the Earth’s matter, people long ago wanted to know what kind of material composition the Earth they lived in, and they also wanted to know how these materials were distributed and distributed.
