动力作用与几种岩石、矿物的转化与新生过程及其地质意义

构造动力作用可引起地壳局部地带一系列能量的转换。岩体发生断裂时由于局部物理化学条件的改变(尤其是温度、压力、振动),原来岩石物质成分和结构变得不稳定。在某些外动力地质作用下,特别是水的积极参与下,导致局部岩石矿物的新生与转化。不同原岩转化的方式及产物各有所异。文中引用了具体的地质实例和个别实验资料,阐述了在动力作用下几种岩石、矿物的转化过程,并说明了这种地质转化的理论和实际意义。

THE DYNAMIC FUNCTION OF THE EARTH AND THE CHANGES, NEWBORN PROCESS AND THE GEOLOGICAL SIGNIFICANCE OF SOME ROCK-MINERALS

The tectonic dynamic process can cause a series of transitions of energy.When rock mass is cracked, the composition and texture of rock become unstable because of the changes of physical and chemical conditions ( especially temperature, pressure, and vibration ) . The ' participation of some exogenious processes, (especially the active participation of water ) led to the newborn and conversion of partial rock-minerals.The way of conversion and the products of the primitive rock were different from each other. In this paper the author quoted some concrete geological examples and different experimental data to illustrate the conversion of some rocks and minerals under the action of dynamic force.The author also explained the theoretical and practical significance of the conversion.
