摘要

本文论述了非冰川区山地和平原边界上的早更新世-新更新世-第四纪沉积物的地层勘探成熟度状况。材料分析表明，现有地层方案的基本原理不充分，根据现有地层方案，这些地区的冲积阶地阶梯是在始新世、新更新世和全新世依次形成的。对代表性剖面进行了修订，为其提供了地质年代数据，对年龄和遗传诊断的准确性进行了评估。

PROBLEMS OF AGE AND GENETIC DIAGNOSTICS OF QUATERNARY DEPOSITS IN THE VALLEY OF THE YENISEI RIVER MIDDLE COURSE (YENISEI – LOWER ANGARA STRATIGRAPHIC REGION AND THE MINUSINSK BASINS AREA)

The article is devoted to the state of stratigraphic exploration maturity of the Eopleistocene – Neo-Рleistocene Quaternary deposits on the boundary of mountain and plain territories in the non-glacial area. The material analysis shows an inadequate rationale of the existing stratigraphic schemes, according to which the ladder of alluvial terraces of these territories was formed sequentially during the Eopleistocene, Neo-Pleistocene and Holocene. The revising of representative sections was carried out, the provision of them with geochronological data, the accuracy of age and genetic diagnostics were evaluated.
