The First Quantitative Evaluation Data on Vendian Metamorphism in the Eastern Part of the Bashkir Meganticlinorium

Resumo

This paper reports the data on the P–T parameters of the Vendian metamorphism within the eastern wing of the Bashkir Meganticlinorium. Regular near-EW variations in the P–T parameters are due to the fact that the Late Vendian Southern Urals developed under compression resulting from orogenic movements in the Timanides fold region. The stress metamorphism is specified by the “near-fault” nature, when the metamorphosed rock zones alternate with unaltered deposits.
