چکیده [English] | ||
Qooshchi granite has been intruded as an anorogenic, A type, within plate granite in an area north west of Orumieh Lake in western Azerbaijan, northwest Iran. The Precambrian crystalline basement has been intruded by gabbros and diorites. The gabbros are tholeiitic and metaluminous and are suggested to have been converted into alkalic through calc-alkalic compositions during K- and Si-metasomatism. The resulting granitic rocks (leucometasomatites) appear as apophyse-like bodies within the gabbros and in the marginal parts of Qooshchi granite. Any further rise in the temperature could have caused melting of the metasomatized rocks and their subsequent recrystallization as pink Qooshchi granite | ||
