The problem of the source of mineral dust, which makes up the loess-paleosol sequence of Ciscaucasia, remains relevant. One of the main approaches to solving the problem is the spatial analysis of the structure and composition of the loess. Based on the core analysis of three boreholes, a sublatitudinal cross-section of the loess-paleosol sequence...

The origin of the loess deposits of the Cis-Caucasus Region, which form an almost continuous cover on the plains from the Sea of Azov to the Peri-Caspian Depression, is one of the controversial issues of paleogeography of the southern part of European Russia. The remarkably high thickness (up to 140 m) and extended coastal outcrops in the west and...

Происхождение лёссовых отложений Предкавказья, образующих практически сплошной покров на равнинах от Азовского моря до Прикаспийской низменности, остаётся одним из дискуссионных вопросов палеогеографии юга Европейской России. Феноменально высокая мощность лёссовопалеопочвенных серий (ЛПС) на востоке региона (до 140 м) и протяжённые береговые обнаже...

A tephrochronological study of the core HOR-1 of bottom sediment from Lake Khorlakel, located 24 km northwest of the Elbrus summit, was carried out. The core was 253 cm length. Deposits are represented by interbedding of thin-layered loams and bio-mineral silt. Six intervals of increased content of cryptotephra from 37,000 to 111,000 shards g dry w...

Due to the high preservation of the loess series and the availability of coastal outcrop sections loess cover of Western Ciscaucasia has ample opportunities for spatial paleogeographical reconstructions for the Middle and Late Pleistocene. Currently, the level of knowledge on the structure and composition of the loess-paleosol sequences of Western...

Boreholes exposed the structure of the loess cover on four key sites along the line from the Eastern Azov region to the Terek-Kuma plain. In order to obtain the most preserved loess paleoarchives, the profiles and boreholes were established located at subhorizontal flat interfluves unimpaired by modern and relict erosion. A stratigraphic subdivisio...
