初论“构造流体动力学”

研究发现地壳中存在着大量的流体，它们以气体、液体、岩浆的形式存在于地壳的不同深度，甚至地幔中。这些流体夹杂在地壳之中，既是各种构造活动的环境因素，也是一种活跃的动力因子；既是物质和能量转移和传递的载体，也是多种能源和矿液的实体。对于地壳这个固、液、气多相共存体，受动力作用而呈现出来的非线性运动过程的种种力学问题，已无法用传统的构造地质学知识或经典的渗流力学来解释。很多现象促使我们去探索一种新的方法或思路，从新的角度去研究这一课题。文章提出“构造流体动力学”这一概念，作为研究地壳浅部流体与地壳构造关系的学科，为今后进一步深入研究这方面的问题勾画出一个初步的轮廓。

PRELIMINARY DISCUSSION ON “STRUCTURE FLUID DYNAMICS”

In has been found there is plenty of fluids in the crust in the forms of gas, liquid, and magma at different depths of the crust, even mantle. They perform not only environmental factors for tectonic activity, but also an important active power; they are the transferential carrier of matter and energy, in fact, they also function as the material body of many energy resources and mineral solutions. For the crust, which consist of solid, liquid and gas, it is difficult to explain the mechanics problems of nonlinear movement process, caused by dynamic power, by the classical structural geology or seepage dynamics. A lot of phenomena spur us to seek a new method or idea to study these problems from a new point of view. In this paper, we propose a new concept, Structure Fluid Dynamics, as a subject, to study the relationship between the fluid and the tectonic activities in the shallow crust. The present paper gives a preliminary outline for further research on these problems.
