【摘要】 本文主要根据碳、氧同位素分馏机理、影响因素和组成特征,对碳酸盐岩的沉积、成岩、变质等作用进行了研究。研究表明,碳、氧同位素的组成特征与沉积环境、成岩程度、变质程度、生源物构等有着密切关系。更多还原

【Abstract】 Based on fractionating mechanism, controlling factors, the carbon and oxygen isotopic composition sedimentation, diagenesis and metamorphism carbonate rocks are studied in this paper. It is suggested that the isotopic com-position ofcarbonate rocks could be closely related with the sedimentary environment, diagenesis metamorphism and the source materials of the carbonate rocks, as well as with the maturation of organic matter.更多还原
