前言现代成矿理论是根据地壳有规律不可逆演化的基本理论和伴生矿床建立起来的。最近在解释地球早期历史方面的进展有力地促进了这一理论的进一步发展。地球早期历史一般认为是地质前期和太古宙时期的总和,时距为45—25亿年。本文使用的“早期历史”一词具另一种意义,即包括太古宙和早元古宙(38—18亿年)。有两个理由证明这种研究问题方法:1)太古宙和早元古宙构造之间紧密相连,而在许多地区晚元古宙构造与显生宙相似。2)缺少地质前期的成矿作用资料。
Introduction The modern mineralization theory is based on the basic theory of irreversible evolution of the crust and the associated deposits. Recent progress in explaining the early history of the Earth has strongly contributed to the further development of this theory. The early history of the earth is generally considered to be the sum of the pre-geological and Archean periods, with a time interval of 4.5-25 billion years. As used herein, the term “early history” has another meaning, namely the Archean and Early Proterozoic (3.8-18.0 billion years). There are two reasons to justify this research problem: 1) the Archean and Early Proterozoic structures are closely connected, while in many areas the Proterozoic structure is similar to the Phanerozoic. 2) The lack of geological information on the mineralization.
