碳酸盐岩石变形显微构造与宏观构造关系研究

RESEARCH ON RELATION BETWEEN MICROSTRUCTURES AND MACROSTRUCTURES OF DEFORMED CARBONATE ROCKS

碳酸盐岩石变形组构及其优选方位的实验研究得到比较完善的发展，但应用于解释自然界复杂的地质构造变形还存在许多困难。本文将碳酸盐岩微观构造分析与宏观构造研究紧密结合，重点研究了浅层次（铜陵地区）和中一深层次（北淮阳地区）构造环境中碳酸盐岩的显微构造特征、变形行为及所揭示的宏观构造信息，为一系列地质问题的分析提供了充分的微观依据。

Although experimental researches on microfabrics of deformed carbonate rocks and their preferred orientations have been well developed,there still are difficulties in their application to the explanation of the complicated natural structural deformations. The principal aims of this study are: (1) to compare deformation behaviour and micro fabric characteristics of the deformed carbonate rocks at shallow(Tongling area) and intermediate-deep levels (Bet Huaiyang area); (2) to improve our knowledge of the microstructures of deformed carbonate rocks by relating to the results of microfabric studies. Based on the microstructures of the marbles in the contact zone of granitic intrusives,two types of emplacement mechanism of granites are identified in the Tongling area, Auhui. A study of the calcite mylonites in the ductile shear zone of Bet Huaiyang of north Da Bieshan mountain was also made.
