hydrothermal mineral deposit in nigeria

mineral deposits were identified. The identification of the hydrothermal alteration zones werecorrelated with the geological map and the ground -truth coordinates of already existing mines ...

In Nigeria, there has been very little research in using remote sensing techniques to identify mineral deposits. One of the few carried out was (Kudamnya et al., 2014) who applied band ratio technique and colour composite to map location of hydrothermal alteration within the Maru schist belt of Northwest Nigeria.

mineral exploration and its geoenvironmental considerations, the secondary effects in rocks that host ore deposits associated with hydrothermal systems are important (Hanna, 1969; Criss and Champion, 1984) and magnetic surveys may outline zones of fossil hydrothermal activity. Because rock alteration can effect a change in bulk density as well

Coal Mineral Deposits In Nigeria And Its Uses. Coal Deposits - Some Africa countries like Nigeria is blessed with coal rich states especially Enugu which is known as the "the coal city" because of its vast coal deposits, other states include; Benue, Kogi, Delta, Kwara, Plateau, Abia, Anambra, Bauchi, Edo,...

A hydrothermal vent is a fissure on the seafloor from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart at spreading centers, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents.

Satellite Remote Sensing for Mineral Deposit Assessment of Clay in Mubi Local Government Area of Adamawa State, Nigeria more by Bulus Luka Gadiga, Bulus Gadiga, and Adegoke K Martins The conventional method for hydrothermal altered/Mineral deposits using Lands at TM image is an effective tool in the field of Remote Sensing.

Mineral deposits in Nigeria? ... Hydrothermal deposits form from hot, metal-rich fluids that are left during the late stages of the movement and colling of magma. ... For a mineral deposit to be ...

Mesothermal mineral deposits are formed at moderate temperature and pressure, in and along fissures or other openings in rocks, by deposition at intermediate depths, from hydrothermal fluids. Epithermal mineral ore deposits are formed at low temperatures (50-200 °C) near the Earth's surface (<1500 m), that fill veins, breccias, and stockworks.

deposits have been relatively less studied. Most of the studieswere centered onthegeology and origin of the lower Benue lead-zinc-copper deposits but which was always projected to the upper Benue TroughZurak-Wase lead-zinc deposits. The magmatic-hydrothermal model (Farrington 1952,Orajaka 1965 and Nwachukwu 1975)

In this investigation, the applicability of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Hyperion data-sets were evaluated in discriminating hydrothermal alteration minerals associated with geothermal systems as a proxy in identifying subtle Geothermal systems at Yankari Park, Nigeria.

complex sulphide ore deposit in Ishiagu, in Ebonyin State, South Eastern part of Nigeria. A semi-geological study revealed characteristic hydrothermal vein deposits of the complex sulphide ore. Mineralogical analysis revealed the presence of siderite, sphalerite, galena, quartz, and traces of pyrite and copper bearing minerals.

These wall rocks are either biotite granites from which the hydrothermal fluids originated or basement rocks or any other rocks which the biotite granites intrude and their residual hydrothermal fluids have invaded. The hydrothermal fluids appear to have been rich in alkalis (Na +, K +, etc.), rare elements (Be, Zr, F, REE, etc.) and siliceous ...

Whole rock and mineral extracts from Nigerian goldfields of late Proterozoic age are significantly more radiogenic than those from the much younger Mesozoic lead-zinc mineralization in the Benue Trough, their common formation by hydrothermal processes notwithstanding. Their marked contrasts in lead isotope compositions can be attributed to differences in source reservoirs, structural settings ...

The Ishiagu lead-zinc deposits of southeastern Nigeria are associated with folded shales of the Asu River Group. The Pb-Zn mineralization is restricted to a series of closely spaced, steeply dipping subparallel fractures which trend NW-SE and typically form en-echelon patterns.

Coal mining processing plant in Nigeria. This coal mining project is an open pit mine located in Nigeria, announced by mining company - Western Goldfields - that it has discovered 62,400,000 tonnes of proven reserves of coal deposits worth US$1.2 billion which could be used for the generation of electric power...

Cassiterite is a tin oxide mineral, SnO 2.It is generally opaque, but it is translucent in thin crystals.Its luster and multiple crystal faces produce a desirable gem. Cassiterite has been the chief tin ore throughout ancient history and remains the most important source of tin today.

Abstract. Three types of tourmaline occurrence have been identified in the area of Bin Yauri, Nigeria, mesothermal lode-gold mineralization. These are: (1) stratabound tourmalinites in pelitic metasediments, (2) tourmaline in a hydrothermal alteration assemblage within hornfelsed wall rocks, (3) tourmaline in auriferous quartz and quartz-carbonate veins.

The mineral assemblage typical of greisens in Younger Granites originated due to the breakdown of original granitic constituents by hydrothermal fluids which also transport and deposit silica, alkalis and some metals, such as tin, molybdenum, niobium, tantalum, tungsten, Primary mineralization in Nigerian ring complexes 225 []AURA N

Man knew more about gold itself and lusted for it much before he understood the geology of hard rock gold or its deposits. Man had to learn about hard rock extraction methods and how to locate those gold deposits just to satisfy the thirst for that yellow metal.
