Utwory pyłowe Kotliny Batsumber i doliny Sugnugurin-goł

Abstract

Dusty forms were found among the Quaternary crusts in the Chentej Mountains in Mongolia. The paper shows their characteristics: an attempt also is made to define the sedimentation conditions of those macroscopically loess-like forms. Their occurrence in the Sugnugurin-gol and Batsumber Valleys was investigated. Three stages of these forms arising were differentiated. Two humid phases wherein weathering-slope crusts had been formed were separated by a dry period with Eolian processes dominating.
