The intrusion of Boroujerd Granitoid Complex into the metamorphosed pelitic rocks has resulted in the formation of pelitic hornfelses and anatectic migmatites in its metamorphic aureole. The effective melting reactions include fluid-present and fluid-absent. Fluid-present melting reactions may have consumed the whole free fluid in the aureole as a result of which melting process continued throu...

The Baft ophiolitic mélange, covering an area approximately 150 Km2, is located in the Esfandaghe-Khamrood melange belt. The main part of intrusive rocks in the Baft ophiolitic mélange consists of gabbros, mostly isotropic and occasionally as pegmatitic rocks. Plagiogranites, as veins and small outcrops, are common along with gabbros and doleritic dikes through the area. Plagiogranites consist ...

The chromitite ores of Sabzevar ophiolitic zone could be divided into two groups of high Cr and high Al. The concentration of Cr2O3, As, S and some heavy metals (Cu, Ni, Ag, Co, Zn) is higher in high Cr samples; while high Al chromitites show higher concentration of Al2O3, SiO2, TiO2 and other trace elements. The high Cr chromitites have higher PGE than Al-rich samples and PGE concentration inc...

Niabad-Qalaje ophiolitic complex is part of Sarvabad ophiolites in Kurdistan that exposed in northwest of Iran and the north of Kermanshah Ophiolites. The complex located in north of Zagros orogeny, consists of lens form, tectonically dismembered ophiolitic sequences located along the main Zagros trust. The ultramafic part includes serpentinized dunite and wherlite, serpentinite and chromitite ...

The Kermanshah ophiolite complex is located in outer Zagros ophiolitic belt and consists of both mantle and crustal suites as remnants of southern branch of the Neo-Tethys Ocean in Iran. Chemical composition determinative diagram of minerals indicates that olivine in dunite, harzburgite and lherzolites has forsteritic composition and in wherlitic rocks is chrysolite in composition likewise orth...
