APPLICATION OF CARBON-OXYGEN ISOTOPES TO CARBONATE ROCKS

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.
