petrography, geochemistry and tectonic setting of salmabad tertiary volcanic rocks, southeast of sarbisheh, eastern iran
introduction the area reviewed and studied in this paper is located 5 km southeast of sarbisheh city at eastern border of the lut block (jung et al., 1983; karimpour et al., 2011; richards et al., 2012) in eastern iran between 59° 47′ and 59° 53′ e longitude and 32°30′ and 32°34′ n latitude. the magmatic activity in the lut block began in middle jurassic (165-162 ma) and reached its peak in ter...
متن کاملPetrography, geochemistry and tectonic setting of the Gharabolagh intrusive mass in North Hashtrud, East Azarbaijan
The plutonic body of Bostanabad-Meyaneh belt formed during the Cenozoic magmatism on the weast Alborz-Azarbaijan zone. The Oligocene plutonic rocks consist of alkaligranite, granodiorite and biotitegranite, intruded into the Eocene volcanic-sedimentary rocks. The predominant textures are granular, graphic and perthite. Geochemical evidence reveals that they are cogenetic and have features typic...
متن کاملPetrogenesis and Tectonic Setting of the Young Volcanic Adakitic Rocks in Darehzereshk’s Hassan abad (SW Yazd)
Sciences, Kharazmi University Introduction Petrogenesis of continental magmatic arc is more complicated than oceanic arcs. Because some various parameters affect the composition of magmatism in the congenital margin, such as continental crust contamination, mixing with crustal magmas and the deformation phenomena from primary mantle magma (Martin et al., 2005; Eyuboglu et al., 2018; Pawley and...
متن کاملPetrography, Mineralogy and Geochemistry of Kuhkamar Shale in the Roum section (South of Qayen): Application for Provenance and Tectonic setting
The Kuhkamar shale with a thickness of 354 m is composed of siliciclastic rocks (sandstone and shale). Petrography studies of the sandstones in this area show two petrofacies including arkose and sub-arkose. These sandstones composed of sub rounded to moderately sorted; therefore, compositionaly to texturaly, they are immature to submature with mono and polycrystalline quartz and k-feldespar. I...
متن کاملPetrography and geochemistry of the Kahrizbeyg intrusion, southwest of Zanjan
The Kahrizbeyg pluton is located northwest of Iran in Central Iran zone. It is emplaced into the Cretaceous limestones in which contact metamorphism has happened. Meanwhile, rock fragments of this pluton are found in conglomerate units of Early Oligocene Lower Red Formation. Therefore, the relative age of pluton is between Cretaceous and Oligocene. The Kahrizbeyg pluton consists of granite and ...
