On the problem of Irendyk Formation genesis West-Magnitogorsk zone, South Urals

Abstract

The Irendyk formation is wide spread in the West-Magnitogorsk zone. It extends in submeridional direction continuously from the border of the Orenburg region to the latitude of Miass city. The previous researchers compare Irendyk volcanic rocks with modern island arcs. According to petrogeochemical data of the Irendyk basalts the authors are attributed them to two types nearly equal to island arc and intraplate mantle.
