Abstract

A set of methods (seismoacoustic profiling, analysis of continuous borehole sections, stratigraphic studies on malacofauna, and radioisotope age dating) was used to identify the Novocaspian, Mangyshlakian, Khvalynian, Atelian, Hyrkanian, and Upper Khazarian horizons in the Upper Quaternary deposits of the Northern Caspian shelf. Based on AMS radiocarbon and uranium-thorium dating, the time of their accumulation is determined, respectively, in the intervals of 0 to 8.5, 8.5 to 13, 13 to 50/60, 50 to 70, >60 to 120 and more than 120 000 years ago.

论里海北部上第四纪沉积的年代

摘要采用一套方法（地震声学剖面、连续钻孔断面分析、麦拉卡动物地层研究和放射性同位素年代测定）确定了北里海大陆架上第四纪沉积中的新里海地层、曼吉斯拉克地层、赫瓦利年地层、阿特利年地层、希尔坎年地层和上哈扎尔年地层。根据 AMS 放射性碳和铀-钍测年法，它们的堆积时间分别被确定为距今 0 至 8.5、8.5 至 13、13 至 50/60、50 至 70、60 至 120 和超过 120 000 年。
