Statistic Indices for Bowl- And Diapir-Like Morphostructures of Vertisols in Vorontsovo Depression (Padi)

Abstract

Under description is a profile configuration represented by stratified bowllike morphostructures with the increased thickness of darkgray humus horizons and diaperlike morphostructures consisted of the olive-brown material ascending from the lower horizons in Vertisols developed on the bottom of a huge closed depression (padi) in Eisk peninsula. Histograms are presented to show statistic distribution and non-parametric statistic indices for morphometric characteristics of the above morphostructures. The statistic relationship between the morphometric indices is estimated. Under discussion is also the genesis of such morphostructures in Vertisols.
