The lithological-facies zoning of the Neo- and Eopleistocene sediments of submarine continental margin of Southwestern Africa was described for the first time using deep-sea drilling data. Corresponding maps with isopachs were processed using A.B. Ronov’s volumetric method to calculate the quantitative parameters of sedimentation for the distinguished types of Pleistocene sediments. The accumulation rates of terrigenous and carbonate sediments increased during Pleistocene. The Benguela upwelling was more intense in the Eopleistocene than in the Neopleistocene, which is supported by the corresponding increase of accumulation rate of siliceous and carbonate–siliceous sediments.

非洲西南部海底大陆边缘更新世沉积物

首次利用深海钻探资料描述了非洲西南部海底大陆边缘新世和更新世沉积物的岩相分带。使用 AB Ronov 的体积法处理带有等厚线的相应地图，以计算不同类型更新世沉积物的沉积定量参数。更新世期间陆源和碳酸盐沉积物的堆积速率增加。本格拉上升流在始更新世比新更新世更强烈，这得到了硅质和碳酸盐-硅质沉积物堆积速率的相应增加的支持。
