| 摘 要： | 引言通过天然变形岩石的岩组分析,恢复岩石变形时的应力状态,结合地质观察,确定构造运动的来向和性质(较小的区域內),对构造地质学、矿田构造学和岩石学研究都有裨益。从岩石的实验变形出发,在给定的应力条件下研究变形岩石的组构变化,作为天然变形岩石组构分析的依据,也是不可缺少的一部分。近年来,不少地质学者愈来愈注意到天然变形的碳酸盐岩石的岩组学工作。到目前为止,对碳酸盐岩石(如变质白云岩)的岩组分析和动力学解释有两种情况。

| Abstract: | In order to study the mechanisms of deformation of minerals of different granularities, a coarse-grained dolomitic marble from Ch Yang, Hopei, was used as testing material. Using Adam’s cylinder at the confining pressure 1440 Kg/cm2 and the temperature 120℃ under the pressures 2,970—7,840 Kg/cm2, the rock prisms are plastically deformed. Differently oriented rock prisms have different resistances. Under the microscope, the wavy extinction of the mineral constituents becomes more and more distinguished with the increase of the deformation. The translation gliding is mostly distinct by the （0001） plane with any axial translation and torsion. The deformation, therefore, took place largely inside the grains, but the intergranular arrangement is very faint. However, the fine-grained dolomite marble of Hsio Tong Shan, Peking, as we have tested before, is principally deformed into intergranular arrangement rather than inside the grains. |
