建议采用一种方法来评估海洋盆地的地球化学状况。通过对近期沉积物中有机质碳同位素组成及其氢指数与氧指数比的比较研究，黑海化学合成生物生产的重要作用以及喀拉海有机质的广泛氧化成岩作用已得到证实。卡里亚科海沟化学合成生产的相对作用似乎与黑海不同。
An approach is suggested to evaluate the geochemical regime of marine basins. By comparative study of the carbon isotopic composition of organic matter and its hydrogen index to oxygen index ratio in recent sediments a significant role of chemosynthetic bioproduction in the Black Sea, and extensive oxidative diagenesis of the organic matter in the Kara Sea have been demonstrated. The relative role of chemosynthetic production in the Cariaco Trench seems to be different compared to that in the Black Sea.
