Lalezar Granitoid Complex is located in the south-east of Urumieh-Dokhtar volcanic belt and Dehaj-Sarduieh belt (Kerman Province). It contains plutonic rocks with granitoid composition and has been intruded into the Eocene volcano-sedimentary rocks. The plutonic rocks have granite to gabbrodiorite composition with dominance of tonalite and diorite rocks. The main mineral phases are sodic plagio...

The Alvand intrusive complex is located in south of Hamedan in Sanandaj-Sirjan Zone. This complex is composed of mafic to felsic rocks such as gabbro, diorite, tonalite, granodiorite, granite, aplite and pegmatite. Granitoid rocks comprise major part of the complex. Granitoids can be divided into two categories: porphyroid granitoids and hololeucocratic granitoids. Porphyroid granitoids are K-r...

Lahijan granitoid pile, east of Gillan Province, petrographically comprises of mostly two group rocks: felsics (granite, porphyry granite and granodiorite) and mafics (diorite) and in terms of magmatic series belong to subalkaline and are mostly calcalkaline. The contact between the pile and surrounding rocks is faulty and includes myllonitic and cataclastic rocks yet there is no metamorphic ha...

Moshirabad granitoid body is located, as part of intrusive bodies, in Sanandaj-Sirjans zone and crops out elongated with east-west trend. Based on field observation as well as mineralogical characteristics, this suite consists of three main units; diorites, granodiorites and granites, followed by minor gabbros. Mineralogical and geochemical studies show that rocks of this suite are I-type, calc...

Astaneh granitoid intrusion is located in southwest of Arak city that is part of Sanandaj-Sirjan zone.  This intrusive mass alterated under influence of hydrothermal fluids and so propylitic alteration is one of the most important types of alterations in this granitoid. Epidote, sphene, prehnite and quartz are important minerals in this alterated rocks. The weight percent of pistacist in epidot...
