本文在岩石学研究的基础上，利用电子探针、碳氧同位素、包裹体古盐度分析、地球化学分析等测试资料，详细研究了中上扬子台地南北缘深水斜坡及台地边缘相碳酸盐岩成岩作用特征，如早期岩化作用、胶结作用、白云石化作用等。在此基础上对研究区深水斜坡相及台地边缘相碳酸盐岩所经历的成岩环境进行了划分，建立了该区深水斜坡相及台地边缘相碳酸盐岩的孔隙演化模式。 Based on the study of petrology, based on the data of electron probe, carbon and oxygen isotopes, paleo-salinity analysis and geochemical analysis of inclusions, the paper studies the deep-water slope and the carbonate facies Diagenetic characteristics of rocks, such as early lithification, cementation, dolomitization and so on. On this basis, the diagenetic environments experienced by the deep-water slope facies and carbonate facies in the platform are divided, and the pore evolution model of the carbonate rocks in the deep-water slope facies and platform margin is established.
