НОВЫЕ ДАННЫЕ О МОРФОЛОГИИ И СТРОЕНИИ БЭРОВСКИХ БУГРОВ

Abstract

The analysis of morphology and inner structure of Baer's hills in the Lover Volga region and its delta helps to conclude that they arose on the bottom of the "sheet flow". The direction of the laminae within the rock mass of the hills indicates the main direction of the flow being from NE to SW. When water level decreased they emerged over water surface. Sometimes the upper parts of hills or its slopes were being erosed, but on the whole they have persisted. Different types of hills may be distinguished by the character of the bedding. Eolian landforms on the right bank of the Volga are the result of washout of clays in the interhills depressions and deflation of the underlying alluvial-marine sands.
