بررسی ترکیب شیمیایی و دگرگونی کانیها در طول فرایند دگرگونیهای مختلف در منطقه همدان
Metamorphic rocks of the Hamadan region have experienced regional and also contact metamorphism (due to intrusion of gabbro, diorite and granitic bodies), therefore, their mineral assemblages have formed in multiple stages. Evidence of regional metamorphism (M) and contact metamorphisms at the contact of gabbros (M’1) and porphyroid granites (M’2) are separatable, hower At the contact of h...
متن کاملMineralogy, metamorphism and geothermobarometry of the Ghandab metamorphic Complex, SE Fariman, NE Iran
The study area is located about 110 kilometers southeast of Mashhad and approximately 40 kilometers southeast of Fariman. The area is considered to be a part of the central Iran zone. It includes metamorphic rocks with different protoliths consisting of pelitic, carbonate and quartz - feldspathic rocks. The metamorphism in the study area is considered to be a contact regional metamorphism with ...

Metamorphic area, which is a subject of this study, is located in S-Qorveh (Zarineh region), northwest of the Sanadaj-Sirjan zone. According to the recent dating, the S-Qorveh plutonic body consists of a complex of granitoids, granodiorites, quartz monzonites, and gabbros, have intruded into the host metamorphic rocks, about 149-152 Ma and have generated contact metamorphism. Intrusions of vari...
متن کاملDating of Precambrian Metasedimentary Rocks and Timing of their Metamorphism in the Soursat Metamorphic Complex (NW IRAN): Using LA–ICP-MS, U–Pb Dating of Zircon and Monazite
Soursat Metamorphic Complex (SMC) in west of Takab city is one of the polyphase metamorphic terrenes in northern Sanandaj-Sirjan metamorphic belt of Iran. The SMC composed mainly of metasedimentary rocks associated with granitic intrusions. Based on metamorphic rocks, two metamorphic phases could be separate in the complex. M1 is representative of regional metamorphisms which varies from greens...
