Petrochemical characteristics ofthe stratified mafic-ultramafic massifs ofthe Nizhnederbinskiycomplex (NW ofthe Eastern Sayan Mountains)
The rocks of the stratified mafic-ultramafic massifs of the Nizhziderbinskiy complex (NW of the Eastern Sayan Mountains) are divided in chemical composition into three groups: ultramafic (dunites, vehrlites), subultramafic (clinopyroxenites, websterites) and mafic (gabbronorites, gabbro). The binary cards have registered the primary trends of rocks evolution. Taking into consideration the data organized by the collection of the evolved groups of rocks, the massifs of the Nizhniderbinskiy complex are rating to peridotite-pyroxenite-gabbroid formation.
