Abstract: 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.
