The lower to middle Miocene Chenar granitoid stock, a part of Central Iranian volcanic belt, is intruded into Eocene volcano-sedimentary complex in northwestern Kerman in south Central Iran. The Chenar granitoid stock consists mainly of coarse to medium grain granodiorite and monzogranite with subordinate tonalite and syenogranite. Alkali granites as aplitic veins and quartz dioritic dykes freq...
The Mamzar granitoid pluton is located in the Kerman Province and structurally in southeast of Urumieh-Dokhtar magmatic zone. Based on petrographic studies, the granitoid consist of four rock type of diorite, tonalite, granodiorite and monzogranite. They are mainly composed of plagioclase (andesine), alkali-feldspar (orthoclase), quartz, amphibole (magnesiohornblende), biotite and clinopyroxene...
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...
Abstract Granite typology categorizes granitoid rocks based upon distinguishing characteristics that are interpreted to indicate sources, conditions of generation, and, by implication, tectonic setting. Complexities elemental and isotopic geochemistry, however, commonly preclude simple typological interpretation suggest more complex petrogenetic histories. Granitoids from the Songpan-Ganzi terr...
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 ...
Older and younger granitoids are widespread throughout the basement rocks of NE Egypt. Therefore, they are played a significant role in the evolution of the Pan-African crust. The Wadi El Sheikh-Gabal Saint Katherine area comprise three distinctive magmatic granitoid suites, namely: (1) calc-alkaline older quartz monzodiorite-tonalite suite (COG), (2) calcalkaline younger monzogranite suite (CY...
The Maksan granitoid is located in the south margin of Lut block, and southeastern Iran. It composed of granite, granodiorite, monzodiorite, quartz monzodiorite, diorite and gabbro. Compostions of biotite from different rock types of Maksan granitoid, i. e., granite, granodiorite, monzodiorite (Quartz monzodiorite), diorite and gabbro in SE of Iran have been documented by electron microprobe. B...
Modelling the groundwater contamination in the aquifer above a repository for high-level nuclear waste is a complex task. The usual procedure is based on modelling the transport of radionuclides in one or two dimensions only (NAGRA, 2002; Kosakowski, 2004; Keesmann et al., 2006; SKB, 2006; Nykyri et al., 2008). However, modern computing techniques allow to perform simulations in three dimension...
In Iran, the most important tin and tungsten mineralization has occurred in Shah-Kuh granitoid pluton (Lut Block, east of Iran), and Nezamabad area (Boroujerd granitoid complex, west of Iran), respectively. Both mineralizations are mainly accompanied by existence of quartz- tourmaline veins. Nezamabad veins- type tourmalines have dravite composition and have been formed in hydrothermal conditio...
