花岗岩定位机制研究进展

近20年来,由于新理论、新方法和新技术的引入,使花岗岩定位机制的研究取得了很大进展,具体表现在复合定位机制的提出,定位机制控制因素的多样性,研究方法的更新等方面。在花岗质岩浆上升定位过程中,不仅肯定了浮力等作用的重要性,而且特别强调了构造通道、构造空间和构造应力作用方式的重要地位。花岗岩体构造研究的新进展,也为花岗地质岩浆的生成、运移、定位以及构造变形等一系列问题的解决提供了新的思路和有效的方法。

Progresses and Tendences of Study on Granite Emplacement Mechanism

In the last twenty years, it has made a great progress in the study of mechanism of granitic emplacement owing to the introduction of new theories, new methods and new technologies. It is materially shown in that the mechanism of multiple emplacement has been brought forward, and in the update of the controlling factors and the means of study. In the course of rise and emplacement of the granitic magma, it is emphasized that not only the importance of the buoyancy,but also the important status of tectonic channels, tectonic space,and tectonic stress' manner. There has been a much progress in the study of structure of granitic pluton. This provides new ideas and effective measures to resolve the production ,mobilization ,emplacement of granitic magma,and tectonic distortion and so on.
