Description
Summary:The investigation of soil-sedimentary sequences formed in different erosional and depositional environments in the central part of the Selenga Midland (western Transbaikalia region) during Late Glacial and Holocene made it possible to reveal nine periods of activation of exogenic processes and sedimentation and eight stages of intense pedogenesis, to define the specific features of these pedogenesis and sedimentation epochs, and to assess their duration. The data on the intensity of sedimentation and its influence on pedogenesis is demonstrated. Asynchronous development of exogenic processes and pedogenesis related to the landscapeâ “climate heterogeneity of the Selenga Midland have been revealed. The latter is reflected in more distinct epochs of intense exogenic processes in more arid southern areas of the midland and more durable periods of pedogenesis in humid climatic environments of its central part.
