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 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. Coal: Anambra Basin in the Lower Benue Trough is a major coal producing basin in Nigeria where intensive
Mining is the extraction of valuable minerals or other geological materials from the earth. The geological survey agency of Nigeria and the ministry of mines and steel development have reported the occurrence of more than 34 minerals in over 450 locations spread across the entire country, which are in various stages of development.
Coal occurrence, exploitation, Processing, and utilization have strong impact both on human health and the environment. This results from its composition and environment of occurrence. Maiganga Coal occurs in the Gombe sandstone. Result of the petrography analysis of the study area demonstrates high silica content and the presence of some elements in the mine.
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.
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;
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.

The geological setting of Kogi State is unique in view of the occurrence of the two major components of Nigerian geology
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 ...

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 ...
