Visean paleo-relief at the Udmurtian territory

Abstract

Sedimentation of the Visean terrigenous series at the Udrnurtian territory was analysed from the paleogeornorphological point of view. For Malinovian, Bobrikovian and Tula ages paleogeomorphological schemes l:500000 were drawn, based on sediments thickness, the latter being reconstructed considering sediments compression, sand content etc. Main geomorphic features of the area can be described for Visean age on the base of the investigation carried out, and zones can be outlined promising for non-anticlinal oil and gas deposits.
