Petrographical and geochemical properties of plagiogranites and gabbros in Guleman ophiolite

Abstract

Petrographical and geochemical properties of gabbros and plagiogranites of Guleman ophiolite are determined. It was concluded that gabbros can be basic rocks on subduction zone and plagioclase-rich leucocratic rocks (plagiogranite) are differentiation products of fractional crystallization of a basic magma in the magma chamber.
