摘要: 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。Abstract: Based on the study of petrology,using microprobe analysis,stable isotope of carbon and oxygen,inclusion analysis and geochemical analysis,the diagenesis of carbonates,such as cementation,dolomitization,on platform margin and deep water slope in the middle Yangtze platform were studied in detail.And the diagenetic environment was divided and the model of porosity evolution was proposed.
