70年代地球化学迈进了它的壮年期,它在下列几个方面取得了有意义的成就: 一、成矿成岩全过程的较深入了解。一个矿、一个岩体的形成往往经历了几百万年、几千万年,甚至几亿年,十多亿年的长期复杂历史。人类只能看到这些过程的总结局,但是在过去是无法了解、探索其全过程的。近年来,通过微量元素和同位素、成矿成岩模拟实验、热力学计算和气液包体等手段,人们才发现许多矿和岩体都具有比过去设想要复杂的历史。概括说来,它们常是多成因的;物质来源多种多样,形成方式丰富多
Geophysics in the 1970s advanced its adulthood and made significant achievements in the following aspects: First, a more in-depth understanding of the whole process of mineralization. The formation of a mine and a rock mass often goes through a long and complex history of millions of years, tens of millions of years, even hundreds of millions of years, and more than 1 billion years. Humans can only see the conclusion of these processes, but in the past they can not understand and explore the whole process. In recent years, trace elements and isotopes, mineralization diagenetic simulation experiments, thermodynamic calculations, and gas-liquid inclusions have led to the discovery that many mines and rock masses have a history that is more complicated than in the past. In general, they are often multifactorial; they have a variety of sources and are rich in forms
