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 Anambra Basin.
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 ...

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.
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 ...

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.

Nigeria started major production of coal, tin and columbite by the 1940s. In 1956 when oil was discovered, the mineral industries suffered when the focus shifted to mining oil. In the 1960s the Civil War led to expat mining experts leaving the country and mines being abandoned.

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.
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 Lower Benue Trough like other Sedimentary Basins in Nigeria is found to be endowed with mineral resources. The mineral resources so far reported in the Trough by the Geological Survey of Nigeria Agency are discussed below.
