Petrology, geochemistry and origin of Hesaruiyeh Granitoid, east of Zahedan, southweast Iran
Hesaruiyeh granitoid is located about 85 Km east of Zahedan city, in the Sistan suture zone. This granitoid occurs as small stocks in Cretaceous ophiolite melange and Eocene Flysch. This granitoid is composed of granite, granodiorite and diorite. Granite and granodiorite consist mainly of quartz, plagioclase, orthoclase, biotite and hornblende and diorite is composed of plagioclase and hornblen...
متن کاملشیمی کانی‌ها و شرایط فشار – دمای تبلور توده‌های گرانیتوئیدی حاشیه‌ی رودخانه‌ی زاینده‌رود، پهنه‌ی برشی شمال شهرکرد با نگرشی ویژه به حضور اپیدوت ماگمایی
The study area is located within the shear zone of north Shahrekord. There are many small and medium granitoid plutons that have intruded in the metamorphic rocks with Middle Jurassic in age. These rocks show sharp mylonitic foliation and lineation as the results of undergoing strong deformation. Most of these granitoid plutons contain the assemblage of quartz + K-feldspar + plagioclase + biot...
متن کاملPetrology and geochemistry of Aligoodarz granitoid, Western Iran: implications for petrogenetic relation with Boroujerd and Dehno granitoids
The Aligoodarz granitoid occurs in Sanandaj-Sirjan Zone (SSZ), Western Iran. Tonalite, granodiorite and granite are the main rock types cropping out in the area. Comparison of Aligoodarz granitoid with Dehno and Boroujerd granitoids reveals several similarities in their chemical characteristics. Thus, the above mentioned granitoids can be assigned as a co-genetic magmatic suite, in which pluton...

متن کاملژئوشیمی گرانیت پرآلومینیوس دومیکایی میلونیتی پل نوغان، غرب استان اصفهان
Noghan granitoid intrusion is located at the NW of Boin- Miandasht and lies in the Sanandaj-Sirjan structural zone (SSZ). Based on field evidence and petrographic studies, the pluton is considered as two-mica granite that has been strongly affected by deformation and shows a good mylonitic foliation study area. The main minerals in the pluton are quartz, alkali feldspar (microcline and perthite...
