- Abstract
The loess-paleosol sequence of the Alma-Peschanoe section located in the west of the Crimean Peninsula is analyzed. A comprehensive analysis of morphological, physicochemical, and some other features enables us to identify eight paleosols formed under different conditions. The supposed age of the loess-paleosol sequence was determined by the paleofaunal analysis based on the discovery of a tooth from the mouse Micromys cf. bendae. According to the data obtained, the formation of paleosols at the initial stage was rhythmical under dry and moderately warm conditions. The paleosols were formed according to the steppe type of soil formation (Kastanozems in the WRB). Later, the climate changed towards an increase in temperature and humidity, and two red-brown polygenetic paleosols were formed. Their formation was gradual under conditions from arid to hot humid subtropical climate; at the optimal stages of soil evolution, the soils were formed according to the fersiallitic type (Nitisols). At the final stages, paleosols were formed under sharp changes in the regimes of moistening—drying. The studied red paleosols may be presumably assigned to the Sevastopol stratigraphic horizon. The studies performed enable us to characterize the landscape-climatic conditions and to elaborate a concept of the genesis of the soil cover in the Early Pliocene.
