太古代的岩石是地壳中最古老的岩石。这些岩石形成所费的时间几乎占了地球年龄的一半有余。由于时代的久远,它原有的面貌,遭到不同时期地质作用的破坏和改造,人们只能根据掩蔽起来的蛛丝马迹进行探索,因此就成为地质学研究中难度很大而颇为有趣的基础课题。太古代地质学,研究地球早期的演化,对探讨地球起源和生命出现有重要意义。同时,由于当前世界上一些重要的固体矿产,大多产于太古代的岩层中,而且近十年来,无论在理论上还是在找矿实践中都有所突破,因此它在 Archean rocks are the oldest in the earth’s crust. The rock formation costs almost half the earth’s age. Due to the long period of time, its original appearance was damaged and transformed by the geologic role in different periods. People can only explore according to the hidden clues, thus becoming a very difficult and quite interesting basic topic in geology research . Archean geology, the study of the evolution of the earth early, on the origin of the Earth and the emergence of life is of great significance. At the same time, due to the fact that some of the most important solid minerals in the world are mostly produced in the Archean strata and have been making breakthroughs both in theory and prospecting in the past decade,
