岩浆作用与地球深部过程

Magmatism and Deep Geological Process

为纪念马杏垣院士诞辰一百周年而作.首先简述了地球系统科学的基本思想和指导意义.指出岩浆作用实质上是地球各层圈之间相互作用的结果,岩浆是地球各层圈之间物质和能量交换的重要载体.通过众多研究实例,重点讨论了岩浆作用的地球动力学意义:一方面,火成岩及其所携带的深源岩石包体可以当作地球深部的"探针"和"窗口";另一方面,火成岩也是大地构造事件的记录,可以用以恢复古板块构造格局,追溯大地构造演化历史.

This paper is written for commemorating the 100th anniversary of the birth of late Academician Ma Xingyuan. It briefly describes the general idea and significance of the earth system sciences, and it further indicates that magmatism is a result of interaction between geospheres, and magma is the media of transfer of mass and energy between geospheres. The paper discusses with emphasis on the geodynamic significance of magmatism with case studies. On one hand, igneous rocks and their carried deep-seated nodules could be served as lithoprobes and windows to explore the deep earth. On the other hand, igneous rocks are also the records of tectonic events so they could be used to retrace the paleo-tectonic pattern and the history of tectonic evolution.
