摘要
主要介绍了碳和氧同位素的地球化学特征,利用这些特征在沉积环境方面的指示意义分析了潜江盐湖的碳、氧同位素并得出了以下认识:碳、氧同位素值的高低变化与气候的变化和沉积环境的变化具有很好的相关性;潜江盐湖是一个封闭的内陆盐湖,就该湖而言,其碳同位素值可初步确定为-5‰(PDB),其氧同位素值为-2‰(PDB)。
This paper mainly introduced geochemical characters of C and O isotope. Using the significance of these characters in the aspect of sediment environment, this paper analyzed C and O isotope of Qianjiang Saline lake and educed conclusions: there are good relativity between the change of climate and sediment environment and the content's change of C and O isotope from high to low; it is a obturated saline lake of innerland toward Qianjiang saline lake, and the content of C and O isotope was primarily decided that C isotope is -5‰(PDB) and O isotope is -2‰(PDB).
