Since the 1970s, Nigeria has aspired to find viable uranium deposits within its borders, particularly after vast deposits of uranium were discovered in the neighbouring country of Niger Republic ...
Generalized geologic map of south-eastern Nigeria (Dessauvagie, 1975). The associated steeply dipping northwest-southeast trending fissures control the mineralization of the lead-zinc deposits.
The identification of fault segments favorable for uranium mineralization in northern Cameroon (Poli area) is important for understanding the genesis of hydrothermal ore deposits within ...
The south-central basement complex is known to host iron ore deposits within the migmatites complex (Ominigbo E. 2022). He described the deposit, as a hematite-magnetite quartz body, and termed it ...
Primary tin ore deposits are part of magmatic-hydrothermal systems invariably related to late granite phases (tin granites, pegmatites, tin porphyries), and may become dispersed by exogenic processes and then eventually form placer deposits within a few km from their primary source, due to the density of cassiterite, its hardness and chemical ...
The consideration of iron ore as an important mineral for global infrastructure, steel production, and wealth creation has prompted this study to consider its potential within north-central...
Volcanogenic massive sulfide deposits are, in other words, known as VMS ore deposits. These are the metal sulfide type of ore deposits which, for the most part, are lead and zinc. In addition to zinc, they contain silver, gold, and copper in significant amounts. They are formed by volcanic-related hydrothermal processes in submarine settings.
The iron ore potential map was validated using known iron ore mines and deposits, which showed a perfect correlation, and new sites of probable iron ore mineralization within north-central Nigeria ...
Mineral ore deposits in Nigeria are found in igneous, metamorphic as well as sedimentary environments. Lead– zinc occurrences in Nigeria are associated with saline water intrusion or …
may be more profitable to mine an ore deposit containing 35% magnetite and 0.5%S as impurity rather than mining an iron ore deposit containing 45% magnetite and 2.0%S as impurity. Fig (a)-(d) are the macro-view of four different types of iron ore (Michaud, 2016) [21]. Fig 1: The macro-view of iron ore deposits: (a) Hematite, (b)

Nigeria's copper ore deposit is estimated to be over 10,000,000 tons [14] and is found in Nasarawa [15]. A large nickel deposit is at Dangoma, Kaduna State [16] .
To explain the common characteristics of mesothermal gold deposits, in particular the fact that the mineralogy of deposits is partly related to the host-rock environment, and the provinciality of the isotopic signature of deposits, it has been suggested that mesothermal gold deposits are formed by CO 2-rich fluids that originated by ...
Ground magnetic profiling was deployed to delineate the occurrences of ore and marble minerals within the study area, Okpella, Edo state, Southern Nigeria.
Gold is found in some African countries such as Nigeria in varying quantities, as a natural resource deposit mainly found in the Northern part of Nigeria. It is prominently located in Iperindo in Osun State and other areas near Maru, Tsohon Birnin Gwari-Kwaga, Gurmana, Anka, Malele, Bin Yauri, and Okolom-Dogondaji.
Achievers J. Sci. Research Based on several years of research on the Nigeria's iron ore deposits and a review of existing body of knowledge on the apparent failure of
The Abu Gaharish mineralization comprises Au-rich NNE-trending quartz veins, and their surrounding shear zone is found hosted within a Neoproterozoic Sn-W-bearing monzogranite pluton and intersects the metavolcano-sedimentary assemblage at its eastern contact. The ore mineralogy consists of pyrite, galena, chalcopyrite, sphalerite, and gold, with …
This paper examines the types of ore deposits in Nigeria. Ores of iron, tin-niobium-tantalum deposits, and precious metals in the Nigerian basement complex are predominantly associated with the metasediments (gneisses and …
Lead ore is primarily composed of lead sulfide (PbS), which is the most common mineral form of lead. Other minerals that may be present in lead ore deposits include cerussite (lead carbonate, PbCO3), anglesite (lead sulfate, PbSO4), galenite (lead sulfide, PbS), and other lead-bearing minerals. The concentration of lead in lead ore deposits can vary widely, ranging …
The mapping of lithology, structures, and hydrothermal alteration zones in Kaiama, northcentral Nigeria, was carried out to locate possible gold mineralization zones.
of Kogi State, Nigeria. The iron ore deposit is on the eastern part of Kogi State, ten kilometres north of Okene Township. The company (NIOMP) is located within latitude 8° and 9o and longitude 7o and 8o as shown in Figure 1. Six main rocks identified on the Itakpe iron ore deposit include granite gneiss, amphibolites, quartzites,
It is well known that the majority of the world's ore deposits are found in Precambrian rocks. The basement rocks in Nigeria form a portion of the Dahomeyan or Trans-Sahara Mobile Belt which includes part of Ghana, Togo, Benin, Nigeria, Chad and Cameroon, stretching northwards through Niger to Algeria (Fig. 3).
industrial minerals, iron ores, bitumen and coal deposits form the c ore of a "roadmap" for the revitalization of the minerals and mining sector, with the main objective of increasing its ...
The iron ore potential map was validated using known iron ore mines and deposits, which showed a perfect correlation, and new sites of probable iron ore mineralization within north-central Nigeria were revealed. This article will serve as a guide for stakeholders in the exploration of iron ore deposits.
At a certain height, the metals precipitate from the ascending fluids. The ore deposit has a typical, well-defined shape that resembles the cap of a mushroom. Its "stem" is the volcanic vent, which has solidified into porphyry and then …
