摘要
花岗质岩浆的生成、分异过程不仅与物理-化学条件有关,而且受控于区域构造。花岗质岩浆的上升、侵位机制除取决于岩浆与围岩的流变性质外,也受构造环境的制约。本文主要讨论花岗岩类岩浆在不同构造环境下对岩浆侵位方式的控制机理,并提出在一个完整的岩浆演化序列中,受构造活动影响发生侵位方式改变的可能性。
The process of generation and differentiation of granitoid magmas is con trolled not only by physical-chemical condition, but also is related to regional tectonic event. The emplacement mechanism for granitoid, magmas is determined by rheological behaviour of the magma and the host rock as well as the tectonic, environment. This paper discusses mainly the tectonic condition of the formation of granitoid magmas, the control mechanism of different tectonic environment for emplacement fashion, and poses a possibility of transformation of emplacement fashion as a result of tectonic active in a complete evolution of magmas.
