This paper deals with the typomorphism of alumino-chromian micas from the view-point of mineralogical phylogeny. The authors have investigated the early origin and late evolution of the crust based on 103 samples from different part of the world including 42 Chinese samples analyzed by the authors. The features point to the conclusion that the elements Cr and Al are rich in mantle-derived rocks and crust-derived rocks respectively. Alumino-chromian micas are mainly generated by the crust-mantle interaction in the earlier geological times or related to remobiliza-tion in crystalline basement in the later geological time and sometimes occur in altered ultrabasic rocks in ophiolites. The characteristics of evolution of alumino-chromian micas will be helpful to recognize the geological history from early origin to late evolution of the crust, especially the ore formation. The position of alumino-chromian micas in geological history is also affirmed.
