Geology, mineralogy, and geochemistry of Mashkan barite deposit, north eastern Sabzevar, Khorasan Razavi province
Mashkan deposit is located northern Soltanabad, Sabzevar, Khorasan Razavi province, and tectonically, between Eastern Alborz zone, north Sabzevar ophiolite zone and Binalood zone. Geology of the area includes sedimentary rocks like sandstone, limestone, conglomerate, shale, marl and Eocene volcanic units. Barite mineralization as vein-veinlets with the mainly NW-SE trend has cut off the rock un...
متن کاملEocene Stratigraphy, Facies, Sequenses and Depositional History in Shabraweet Area, North of Suez, Eastern Desert, Egypt
The Eocene rocks in Shabraweet area comprise the Lower, Middle and Upper Eocene stages. Each stage consists of only one rock unit; the Minia Formation, the Mokattam Formation and the Maadi Formation, respectively. The Minia Formation shows angular unconformity relationship with the underlying Cretaceous rocks and disconformity relationship with the overlying Mokattam Formation. The Maadi Format...
متن کاملGeochemistry and evolution of the Neoproterozoic granitoid magmatisms in the Wadi El Sheikh-Gabal Saint Katherine area, Southw
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...
متن کاملStructural and tectonic evolution of the Umm Gheig/ El-Shush region, central Eastern Desert of Egypt
The rocks of the Wadi Umm Gheig/El-Shush area in the central Eastern Desert of Egypt form part of the Nubian Shield, a component of the Neoproterozoic Pan-African Orogeny. The rocks have been divided into three units: (i) low-grade metamorphosed rocks, which consist of metavolcanic rocks interleaved with slices of ophiolitic melange; (ii) high-grade metamorphic rocks, which consist of syn-tecto...
متن کاملGeochemical Characteristics and Chemical Electron Microprobe U-Pb-Th Dating of Pitchblende Mineralization from Gabal Gattar Younger Granite, North Eastern Desert, Egypt
Pitchblende mineralization was studied in the younger granite samples collected from Gabal Gattar, north Eastern Desert, Egypt using electron scanning microscope (ESM) and electron probe microanalyses (EPMA). This study revealed that this pitchblende contains significant Zr content reaching up to (66.80% ZrO2), which suggests that volcanic rocks were probably the source of such a deposit. High ...
