Extensive research have been carried out to assess the radionuclide contents of coal deposits around the world [1, 2, 5, 13, 17–19, 26, 30–32], but information on the radioactivity of Nigerian coal is relatively limited. Yet Nigeria is endowed with abundant coal deposits with enough capacity to generate up to 30% of its energy needs.
The main solid minerals in Nigerias mining industry include coal tin niobium and gold. In 2010 Nigeria produced an estimated 21200 metric tons of aluminium 600 kg of gold 50000 metric tons of iron ore 450000 metric tons of bituminous coal 190 metric tons of niobium columbium and 230 metric tons of tin US Geological Survey.
Geologic Setting In terms of Geology, Enugu occupies much of the highlands of Awgu, Udi and Nsukka. The hills are flanked by the rolling lowlands of Oji River, Anambra basin to the West and Ebonyi (Abome) River basin to the East. Fig 1 belowis the map showing the various formations within the .
The Nigeria coal and lignite resources have an estimated reserve of billion tons and 300 million tons, respectively [1], although most of these coal deposits lie unexplored and abandoned. Coal is being mined at Ezimo, 5 km northwest of the area under ... Location and Geological Setting . The study covers an area of about 85 km. 2.
3 GEOLOGICAL SETTING. The geology of Nigeria, as detailed in Kogbe (1989), is made up of three main rock. groups: mainly Precambrian basement crystalline metamor phicigneousvolcanic rocks;
Like other parts of the world, coal is the oldest commercial fuel, dating in Nigeria from 1916 when 24,000 tons were produced. Production peaked at near one million tons in 1959, before declining to the present insignificant level. This is due to the
industry is recovering worldwide and Nigeria is not left out. Economically coal has many uses. This paper attempts to appraise the economic significance of Nigerian coal resources. Geological Setting The geology and stratigraphic descriptions of sediments in the Benue Trough of Nigeria .
Dec 02, 2015· Coal was first discovered in Nigeria in 1909 at the Udi Ridge in Enugu by a British mines engineer, Albert Kitson. Kitson had been prospecting for silver. By 1914, the year of Nigeria''s amalgamation, the first consignment of coal made its way to the United Kingdom from the newly created ports at Port Harcourt.

2. Geologic setting. The Benue Trough is an intracontinental Cretaceous sedimentary basin in Nigeria. It has up to 6000 m of Cretaceous–Palaeogene sediments of which those before the MidSantonian were folded, faulted and uplifted in several places ( Benkhelil, 1989).

Jul 02, 2010· The Anambra Basin, located in southeastern Nigeria, appears to contain the largest and most economically viable coal resources. The basin covers an area of approximately million hectares and is constrained by the Niger River on the west, the Benue River on the north and the Enugu Escarpment on the east.
administrative capital of modern–day Nigeria. The State lies between longitudes 6 0 42′ and 6 070′ E and latitudes 70 30′ and 7 50′ N. It has a landmass of 29,833 square kilometres. The geological setting of Kogi State is unique in view of the occurrence of the two major components of Nigerian geology

Coal is mined by both surface or ''opencut'' (or opencast) and underground or ''deep'' mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia''s coal is produced from opencut mines.
Coal mining in the Enugu area of Nigeria has generated a lot of mine waste that has been dumped in landfills and surface dumps chosen for convenience and proximity to the waste source rather than environmental, geologic or engineering considerations. Environmental degradation and groundwater contamination has resulted. Structural analysis of the area shows that the geological formations are ...

Stratigraphy, Tectonics Geologic History. The oldest Precambrian rocks in Nigeria likely formed during the Archean or the Paleoproterozoic, forming the Beninian gneiss, in the BeninNigeria Orogen, formed during the Proterozoic PanAfrican crystalline basement rock of the country is grouped as the Nigerian Province, a southern continuation of the central Hoggar reactivated basement.
The Geology of Nigeria is dominated by three major rock types; the crystalline (igneous and metamorphic rocks) and sedimentary rocks both occurring approximately in equal proportions.
The generation and distribution of C 11+ aromatic hydrocarbons has been investigated in 24 rock samples from the Campanian–Maastrichtian Nkporo shales and coals of the Anambra Basin in the lower Benue Trough. The study focused on dicyclic and tricyclic aromatic hydrocarbons identified on gas chromatograms. The distribution of these compounds and their alkyl homologs are strongly controlled ...

May 13, 2019· The Cretaceous Mamu Formation coal samples located within the Northern Anambra Basin were collected, analysed and interpreted using multivariate statistical approach to determine the major, trace and rare elements association with a view to determine the source of the terrestrial rocks, palaeoweathering/climatic conditions and tectonic setting. The dominant oxides such as SiO2, Al2O3, .
