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 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 ...

15 صفحه اولMineralogy, geochemistry and conditions of formation of The Band -e- GhichyCopper-Celestite deposit Torud area, South of Shahrood
Band-e-Ghichy copper deposit is located in the northern margin of the Central Iran structural zone, about 120 km south of Shahrood and 70 km south east of Torud. Copper mineralization occurred in the rock units including sandstone, conglomerate and siltstone with the Oligocene age. Mineralization has occurred in the form of stratiform (syngenetic), stratabound (epigenetic) and supergen (the sur...
