提出了分别测定 CaCO_3沉积物中浮游有孔虫和灰质超微浮游生物绝对沉积量的方法。文章指出,超微浮游生物残骸在深海碳酸盐中占绝对优势。已经查明,印度洋新生代浮游有孔虫和超微浮游生物绝对沉积量变化及其种属数量变化是同步的。确定了超微浮游生物和浮游有孔虫绝对沉积量与超微浮游生物种属数量和浮游有孔虫种属数量之间呈非线形分布。超微浮游生物和浮游有孔虫的最大绝对沉积量是在古新世-始新世初期和新第三纪-更新世,最小沉积量是在晚始新世-渐新世。对于超微浮游生物和浮游有孔虫的种属数量来说,确定在古新世-早始新世为最少,而在中始新世和中中新世-更新世最多。
A method for the determination of the absolute deposition of planktonic foraminiferous and gray matter supernatant in CaCO 3 sediments was proposed. The article points out that ultrafmicrobial plankton remains an absolute predominance in deep-sea carbonate. It has been determined that changes in the absolute deposition of planktonic foraminifer and superficial plankton in the Indian Ocean and changes in the number of their species coincide. It was confirmed that there was a non-linear distribution between the absolute deposition of ultra-plankton and planktonic foraminifera, the number of planktonic species and the number of planktonic foraminifera species. The maximum absolute deposition of ultra-plankton and planktonic foraminifera was in the late stage of Pliocene-Early Pliocene and Neogene-Pleistocene with the minimum sedimentation amount being Late Eocene-Oligocene. For the number of species of planktonic and planktonic foraminifera, it is determined that the population was the least in the Paleocene-Early Eocene, while it is the middle in the Miocene and Middle Miocene-Pleistocene.
