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 ...
The Bazman granitoid is located in the south margin of Lut block, and southeastern of Iran. It composed of granite, granodiorite, monzodiorite, quartz monzodiorite, diorite and gabbro. Plagioclase, feldspar, quartz, hornblende and biotite are the major minerals; sphen, apatite, zircon, magnetite and ilmenite are the main accessory minerals. Amphibole mineral chemistry is calcic in composition a...
Incheh granitoid intrusion is located east of Herris, East-Azerbaijan Province. It intruded into the older rock units including Eocene volcanic – volcaniclastics. Compositionally, this intrusion ranges from diorite-quartz diorite to monzonite. Chemical composition of its major minerals such as feldspars, amphibole and clinopyroxene analyzed using electron probe micro-analyzer (EPMA) for thermob...
Khezr-Abad pluton is cropped out in North-West of Taft. This granitoid seems to be younger than the surrounding metamorphosed rocks, particularly the lower cretaceous limestones and probably is implaced during Oligo-Miocene. The most volumetric abundances of the igneous rocks are: granodiorite, granite, quartzmonzo-diorite, quartz-diorite, and in a lesser amount tonalite, quartz-syenite and ...
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...
The Zahri granitoid body has intruded into the Late Cretaceous ophiolitic rocks syn-tectonically. This granitoid with NW–SE general trend was emplaced along the terminations of Nehbandan shear system in the northern Sistan suture zone during the Early Eocene. Development of magmatic to low temperature solid-state fabrics have shown the progressive deformation with decreasing melt content during...
Late Eocene-Early Oligocene Zouzan granitoid bodies are located in northern part of Lut Block and southeast of Khaf in Khorasan Razavi Province and intruded in metamorphic and sedimentary rocks of Precambrian to Eocene. as a result of subduction of Lut Block under Helman Block ,Lut magmatism and Zoozan granitoids have been formed. The granitoid bodies are composed of granodiorite, monzonite, mo...
