Abstract —The lithological-facies zonality of the Neo- and Eopleistocene sediments from two main areas of the Cordilleran submarine margin is described for the first time. Processing of corresponding maps and isopach schemes using A.B. Ronov’s volumetric method made it possible to calculate the quantitative parameters of sedimentation for the distinguished types of Pleistocene sediments. Terrigenous sedimentation predominated and was intensified during the Pleistocene. The accumulation of biogenic opal and carbonates was more intense in the Neopleistocene than in the Eopleistocene.

科迪勒拉海底边缘更新世沉积物相结构及定量参数

摘要——首次描述了科迪勒拉海底边缘两个主要区域新世和更新世沉积物的岩相带状特征。使用 AB Ronov 的体积法处理相应的地图和等厚线方案使得计算不同类型更新世沉积物的沉积定量参数成为可能。陆源沉积占主导地位，并在更新世期间加剧。生物蛋白石和碳酸盐的积累在新更新世比在更新世更强烈。
