Signs of the aeolian influence on the formation of coastal-marine sand deposits in the Permian (Republic of Tatarstan, Russia)

Учёные записки Казанского университета: Серия Естественные науки, 2019
Sandy deposits can have a different genesis and form in different sedimentation environments. The example of the tar sands of the Early Permian age of the Republic of Tatarstan (Russia) shows the possibility of their complex and polygenic formation with ...

Devonian organogenic buildings of the Urals and adjacent regions of East-Europian Platform and West Siberian

Литосфера, 2015
Several reef-building systems occurred during Cambrian-Devonian on the Urals and adjacent regions of the East-European Platform. The first phase was manifested in the Lower Cambrian within a limited area of the western slope of the Urals.
