Petrography, 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 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 کاملDepartment of Mineralogy , Petrography and Geochemistry
Department of Mineralogy, Petrography and Geochemistry is the oldest Earth science department at the AGH University of Science and Technology. It was created in 1919 as one of the first six departments of the Academy of Mining and was initially named as the Department of Mineralogy and Petrography. The Department was organized by Professor Józef Morozewicz (1865–1941) who chaired the Organizing...
متن کاملPetrography, Major and Trace Elemental Geochemistry of the Ordovician-Silurian Siliciclastics in North of Tabas Block, Central Iran: Implications for Provenance and Paleogeography
The upper part of Shirgesht (UPS) and lower part of Niur (LPN) formations (Ordovician-Silurian) consist of sandstone, shale and limestone, respectively. The petrography and geochemical analysis conducted to evaluate provenance of siliciclastic deposits in order to understand the paleogeography of Central Iran during the Early Paleozoic time. This study shows that quartz and K-feldspar are the m...
متن کاملPetrography and element geochemistry of dolomites of Sibzar Formation, east of Neyshabur
The Sibzar Formation (Middle Devonian) is located about 30 km east of Neyshabur and is composed of lower dolostone with intercalations of sandstone, middle basaltic sill and upper dolostone to limy dolostone, with a thickness of 334 m. Based on the crystal size in this formation, three different types of dolomite (D1, D2, Vd) were identified and according to the textural classification of the d...
