摘要
介绍了洋中脊玄武岩浆、岛弧岩浆、地幔热柱成因的玄武质岩浆、俯冲带岩浆、长英质岩浆、的生成问题;岩浆运移的理论及制约因素;混合岩浆的成因机制及其有关标志。
Base on the thinking that magma is the product of crust - mantle movement, the generation, transport and solidification of magma are main movement form of crust-mantle metcrial (changing accompaning state) and important evalution signal of the crustal and even of the earth, and the theory of magma and facts that exmentation studies rapid increase, the paper briefly introduce some important academic openning and information on magmas of the 29th IGC as fellows.This paper concentrates on introduce generation problems of ocean middle redge basalt magmas, island-arc magmas, mantle plumes generating magmas, subduction zone magmas and felsic magmas; theory and controlling factors of magmas transportation; origin mechanism and its indicator of magma mixing.
