Fluid inclusions and mineral chemistry of some detrital heavy minerals of alluvium sediments from Meluli-Namuhuca area, Mozambique
Geochemistry and fluid inclusions studies were carried out on garnet and beryl from Quaternary alluvium deposits of Meluli-Namuhuca area, Mozambique. Garnet occurs as euhedral large crystals and is commonly brownish red, with a moderate brown hue in transmitted light. Apatite and ilmenite are the common inclusions. Geochemically, garnet is characterized by nearly homogenous chemical composition with...

Geoelectric mapping and characterization of limestone deposits of Ewekoro formation, Southwestern Nigeria
62 vertical electrical soundings (VES) were carried out to map limestone deposits of Ewekoro formation, south-western Nigeria. The maximum current electrode spacing AB/2 was 1 km. The results revealed the occurrence of limestone in all the locations within the third and fourth geoelectric layers with resistivity values ranging from 10 to 100 KWm and thickness range of 15 to 90 m. The resistivity...

Estimation of production function for mines in Iran
Mines as an important sector of Iran's economy have a principal role on supply chain of the most of the economical sectors. The determination of relationship between major production function (PF) factors in mines is one of the necessary activities for efficient management of mine sector. In this paper, the best mine production functions were estimated using information of selected minerals. For this...
