花岗岩形成作用与花岗岩类的成因类型花岗岩形成作用是一种地质现象,就其意义而言可跻身于岩浆作用、变质作用、交代作用和沉积堆积现象之列,在地壳花岗岩层的形成中它起决定性的作用,表现为形成花岗岩类,※其最终产物的成份和体积决定于地质、地球化学和物化因素的总合。根据这些因素,花岗岩形成作用分为硅镁质和硅铝质成岩作用系列[367,370]。 Granite Formation and Genetic Types of Granitic Classes The granite formation is a geological phenomenon that, in its significance, is among the magmatic, metamorphic, metasomatism, and sedimentary accumulation phenomena that occur in the formation of the crustal granite layer Decisive role, manifested in the formation of granitoids, ※ the final product composition and volume determined by the combination of geological, geochemical and physicochemical factors. Based on these factors, the formation of granites is divided into a series of magnesian and silico-aluminous diagenetic series [367,370].
