Lale zar granite batolith is located in the southeast of Urumieh-Dokhtar magmatic belt and Dehech-Sarduieh. This mass includes a low density of tourmaline with nodule,vein and solar morphologies. Less tourmaline occurs in this mass could be due to mass being saturated in the boron. The studied tourmalines are classified in the shourl-dravite series and alkaline group. Most of the substitutions ...

The pegmatitic and aplitic dikes in the Alvand plutonic complex and metamorphic rocks of its contact aureole (hornfelses) are the latest magmatic phase in this area. In addition, at distances away from the Alvand plutonic complex, various pegmatitic-aplitic dikes intruded in the regional metamorphic rocks. Tourmalines from Alvand dikes, observed as nodules and sometimes with graphic intergrowth...

Mollataleb area is located in the north of Aligudarz city, in the Sanandaj-Sirjan metamorphic zone. The regional metamorphic rocks with Upper Triassic-Jurassic age and various granitoid units are the most important geological event that occurred in the area. The development of granitoid masses in Aligudarz area aged Middle Jurassic that intruded into schists. Microprobe analyses of tourmalines ...

Malmir area is located in the east of Doroud city, in the Sanandaj-Sirjan metamorphic zone. The earliest deposits contain a relatively uniform sequence of slates and phyllites with silisic veins and veinlet. Various granitoid units, with Middle Jurassic age, are the most important geological event that occurred in the area. Microprobe analyses of tourmalines in pegmatites and and quartz-tourmal...

Torud-Chah Shirine magmatic arc is located in south of Semnan. This arc is composed of Cenozoic volcanic, pyroclastic and intrusive rocks. The Kuh-Zar in manning province of Bagho is outstanding with Cu-Au mineralization. Mining is restricted to hydrothermal alteration zones in the area. Alteration zones includes propylitic, phyllic, advanced argillic and silicic. The rare association of tourma...
