| 摘 要： | 根据地层、微体古生物组合及碳稳定同位素、微量元素测试等项资料,对乐东30-1-1(A)井区晚第三纪的沉积环境及古生产率进行了分析,认为:经历了浅海—半深海—浅海三个环境演化阶段:浮游有孔虫N_(18)带和N_(21)带沉积早期是古生产率较高及有机碳保存的良好时期。

| Abstract: | A multiple analysis of stratigraphy, micropaleontology, carbon isotope and trace elements is presented from well LD30-1-KA), which allows resolution of Neogene depositional environment and o-ceanic productivity in this region. It is suggested that the depositional evolution of Yingehai Basin involved three stages of neritic-bathyal-neritic environmets. Favorable periods for high oceanic productivity and well preservation of organic carbon have been recognized from the planktonic foraminiferal zone N18 and the lower part of N21. |
