摘要

The stable oxygen and carbon isotope of biological shell carbonate have been extensively applied in the palaeo-climatology and palaeo-environmental research. When measured the isotope composition of shell in situ, the different isotope composition between different shell cross sections will affect the environment significance judgement of shell isotope and have the adverse effect on the environment information extraction. This paper investigated carbon and oxygen isotope of the Corbicula shell, the results shows that the carbon isotope profiles not obvious change in different cross sections, therefore it can not consider the difference between cross sections, and can extend the length of sample path in the sample process to obtain the enough powder to determine the carbon isotope.
