Abstract

This report presents the results of comprehensive studies of loess-like formations that are common within the drainage basins of the Ai and Yuruzan Rivers (Southern Urals). Loess complexes are associated with the third fluvial terrace. The lithological composition, structural, and textural features indicate that the loess were formed like the part of alluvial fans under the third fluvial terrace. The obtained palynological data indicate the formation of deposits in the Middle Pleistocene during the Odintsovo interglacial and Moscow glaciation.

南部乌拉尔地区黄土的分布区域和形成条件

摘要

本报告提出了对Ai和Yuruzan河（南部乌拉尔）流域内常见的黄土状地层进行综合研究的结果。黄土复合体与第三河床阶地相关。岩性组成，结构和质地特征表明，黄土的形成像是第三河床阶地冲积扇的一部分。所获得的古生物学数据表明，在奥丁佐沃冰川间和莫斯科冰川期，中更新世沉积物的形成。
