摘要

本文对米努辛斯克凹陷两个新发现的哺乳动物化石的地质构造、形成条件和古生物材料进行了描述。切尔努索夫测井剖面确定了三种沉积类型。剖面上部为晚全新世陆上沉积。中部以全新世最佳土壤形成痕迹为特征。下部地层为晚卡尔吉尼期—早萨旦期冲积矿床。确定了两个地点的哺乳动物可追溯到撒旦世和全新世的最佳时期。动物群的年龄由剖面上的地层位置和放射性碳定年结果证实。

CHERNOUSOV LOG – THE NEW LOCATION OF LATE PLEISTOCENE AND HOLOCENE MAMMALS IN THE MINUSINSK DEPRESSION (GEOLOGICAL STRUCTURE AND CONDITIONS OF FORMATION)

The paper defines a description of geological structure, conditions of formation and paleofaunistic material from two new locations of fossil mammals within the Minusinsk Depression. Three types of sedimentation are determined for the Chernousov Log section. The upper part of the section is represented by subaerial deposits of the Late Holocene. The middle section part is characterised by traces of soil formation of the Holocene optimum. The lower stratum is represented by alluvial deposits of the Late Karginian-Early Sartanian time. Two locations of mammals dating from the Sartanian and Holocene optimum are identified. The age of faunas is substantiated by their stratigraphic position in the section and results of radiocarbon dating.
