【Abstract】 At present, increasingly detailed studies on the types of ore deposits of w, Be, Sn, Li, Ta, Nd in southern China have been made, but the genetic relationships between various types of the ore deposits, especially between petrological series of yenshanian granites and various types of the ore deposits, have been scarcely touched. The authors attempt to discuss the relationships between types of the ore deposits as mentioned adore and the relationships between various types of ore deposits and various granites from the viewpoint of minerogenetic series or genetic series of mineral deposit. According to the authors, the above-mentioned ore deposits may be considered as of a genetic series of ore deposit of greisen——albite metasomatite which are related to the series of the early Yenshanian granites rich in potassium and to those of later Yenshanian granites rich in sodium.Various ore deposits occurred accordingly with the changing of the composition of the Yenshanian granitic series, from the earlier and middle period to the middle and later, the various types of ore deposits being formed due to the differences of the composition of the mother rocks, of their evolution stages, of structure and of lithological characters. They are a group of types of mineral deposits——the genetic series of deposits which are associated closely in the space, related tightly in the origin and similar or fransitional conerning the mineral associations.This regularity of the granite evolution arises from the differentiation and evolution of the granitic magma formed by the melting of the crust or by the repeated remelting and intrusion, with the gradual generation of the granitic magma which was of lower melting type and rich in Na₂O （Li₂O, F） at the later stage of the evolution.更多还原
