HYDROTHERMAL ORE DEPOSITS TYPES OF ORE DEPOSIT 1. Ores formed by hydrothermal processes 2. Ores formed by igneous processes within the earth 3. Ores formed by sedimentary processes at the Earth's surface A hydrothermal fluid = a hot, aqueous fluid containing dissolved metals in solution. A mineral vein is formed when minerals precipitate in a fracture.
How Minerals Become ConcentratedHow Minerals Become Concentrated, The final way that magmatic processes concentrate mineral resources is through hydrothermal, The two main types of sedimentary mineral deposits are.CassiteriteCassiterite is a tin oxide mineral, SnO 2It is generally opaque, but it is translucent in thin crystalsIts luster and multiple crystal faces produce a desirable gem ...
Hydrothermal mineral deposits are formed when minerals are deposited and concentrated from hot (hydrothermal) waters that are superheated by molten magma and ascend to spring at the earth's surface The sulphide-metal minerals that hotsprings deposit are generally concentrated in the cracks and faults along which the fluids rise to the surface.
Hydrothermal mineral deposits in oceanic crust include metalliferous sediments and encrustations and massive sulfides. The occurrence of these deposits is explained by the hypothesis that they are concentrated at the discharge zones of high intensity subsea-floor hydrothermal convection systems involving the circulation of sea water through oceanic crust and upper mantle at oceanic spreading ...

01-05-2015· The conventional method for hydrothermal altered/Mineral deposits using Lands at TM image is an effective tool in the field of Remote Sensing. The band rationing method was used to create the False Colour Composite (FCC) of the image using Chica-Olma ratio (5/7:5/4:3/1) RGB. This is to enable the identification of spectral reflectance of mineral deposits' within the area of study, the ...
Preliminary investigations in the Younger Granite Province of Nigeria have revealed that precious and semi-precious minerals like rubies, sapphires, emeralds, aquamarine, zircon and fluorite can be found in the region. The gem minerals are shown to have been produced either by direct deposition along fissures, veins and greisens by hydrothermal fluids or as a result of hydrothermal fluids ...

Dolomite Deposits - Nigeria is one of the African Countries with Dolomite deposits and these are located in Abuja, Edo (Ikpeshi and Akoko), Kogi, Nasarawa, Kwara, Yobe, and Oyo.. Dolomite is one of the compositions of limestone that can also be referred to as the sedimentary rock, both Limestone and Dolomite behaves in similar ways when subjected to heat and pressure.
Barite mineralization occurs at Chenarvardeh deposit as layers and lenses in Upper Eocene volcanic and pyroclastic rocks. The host rocks are intensely saussuritized in most places. Barite is accompanied by calcite, Mn-oxides, galena and malachite as subordinate minerals. The amount of Sr in barites is low and varies between 0.11 and 0.30 wt%.
Fluorite, CaF2 is a well-known accessory mineral occurring as vein fillings in rocks, and numerous hydrothermal ore deposits. It commonly occurs in rocks that have undergone hydrothermal activity. Fluorite has no specified ores, but the veins often include some metallic ores, such as silver ores, sulfides of tin, zinc, lead, copper, and several others metals.
After two decades in the United States working on mineral resources development and environmental protection and teaching as adjunct faculty at the University of Phoenix, he returned to Nigeria in 2012 as a Visiting Professor and Dean at the Achievers University, Owo where he lectured and provided leadership in developing academic programs at the new University, as well as collect data and ...

24-12-2020· In Northern Nigeria, the geological and geomorphological setting makes remote sensing a more suitable approach for mineral exploration. This can be attributed to low vegetation cover, as well as the intermittent affiliation of most mineral deposits to hydrothermal alterations (Akande and Fakorede, 1988; Garba, 1988; Garba, 2003).
