| 摘 要： | 花岗岩成因与壳幔作用有着密切的联系,花岗岩成分不单来源于地壳,还有地幔物质的参与,不同程度的壳幔混合可形成类型多样的花岗质岩石。本文简要总结了在俯冲作用、底侵作用、拆沉作用及地幔柱活动过程中花岗质岩浆的形成,并对此类花岗岩的岩石学及地球化学特征进行了描述。鉴于此,可初步判断花岗岩的形成是否与壳幔相互作用有关,但还没有一种统一的模式能对其进行有效的解释。 |
| 关 键 词： | 花岗岩 俯冲作用 底侵作用 混合 壳-幔作用 |

| Abstract: | Components of granite maybe not only derived from the crust but also from the mantle.The genesis of granites has close relationship with the crust-mantle interactions,thus the crust-mantle mixing has been used to study the genesis of granites recently by many researchers.It is believed that the crust-mantle mixing in various extents might form many kinds of granitoids.This article has summarized the generation of granitic magmas in subduction process,underplating process,detachment process and mantle pluming process,and has described the petrological and geochemical characteristics of granites.These features could help us to basically judge if the genesis of granites is related to the crust-mantle interaction,though there is no uniform model which could explain the formation of granites effectively. |
| Keywords: | granite subduction underplating mixing crust mantle interaction |
