چکیده
This paper presents the mineralogy and chemical composition including iron ore impurities to ascertain its suitability for industrial applications. The Asanje deposit is hosted in Precambrian volcano-sedimentary rocks Mayamaya-Hombolo Belt Dodoma region, within Lake Nyanza Superterrane. Iron ores are found two parallel ridges trending NW-SE. Ridge I occurs as vein banded hematite-type II massive-type ore. A total of 24 samples were analysed major trace elements by XRF petrographic studies optical microscopy XRD. XRD results revealed that hematite goethite main components quartz gangue mineral ores. data shows Fe2O3t content ranges from 20.8 87.3 wt% with an average 52.7 wt%. concentrations such SiO2, Al2O3, P2O5 S 37.9, 0.9, 1.2, 0.2, respectively. By comparison, has greater (30.5–87.3 = Avg. 64.66 Fe2O3t) than (20.8–78.22 48.68 Fe2O3t). Based on composition, quality categorised low medium grade, can be used metallurgical cement industries.

Eocene magmatism with intermediate-acid tuffs and volcanic rocks, the host to the Nodoushan deposit in Yazd province, intruded by Oligocene early diorite and later granite plutonic rocks. The former involved in iron skarn (containing epidote and euhedral grossularite) to the north and northern part of the deposit, the latter contributed to fault-controlled Zn-Pb deposit. The structural features...

Temelieh area is located about 20 Km northwest of Selseleh (Lorestan Province). Geologically, the area is a small part of the Harsin radiolarite complex. Petrography consists of radiolarite, peridotite, gabbro, plate dikes, basalt and andesite, limestone, and marble. Manganese mineralization occurs as vein-veinlet and is mainly formed in faults, joints, and fractures that crosscut in radiolarit...
