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.

Keywords

Neotethys, supra-subduction zone, plagiogranite, gabbros, Taurides
