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.
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).
Petroleum and Coal Pet Coal 2017 59 2 233 The Nigeria coal and lignite resources have an estimated reserve of 1 5 billion tons and 300 million tons respectively 1 although most of these coal deposits Geological map of the study area with a NW SE cross section Inset is the geologic map .
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.
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
in similar geologic settings in order to understand sedimentary signatures and events that can offer a better understanding of the endCretaceousCenozoic transition. 2. Tectonics setting of the Anambra and Niger Delta basins. The Anambra and Niger Delta Basins are both located in Southern Nigeria .
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.
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;
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.
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
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.

Abstract: Geologic mapping of the study area revealed three dominant lithologic units namely: bandedgneiss, migmatitegneiss and granitegneiss ...
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.
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, .
Chemistry of Maiganga Coal Deposit, Upper Benue Trough, North Eastern Nigeria. Journal of Geosciences and Geomatics . 2014; 2(3):8084. doi: /jgg232. Correspondence to: Usman Shehu Onoduku, Geology Department, Federal University of Technology, Minna, Nigeria.
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
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.
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.
Continue reading to learn geological facts about this precious metal and why you should consider investing. Brief Overview of Copper in Human History. As one of the first metals ever mined by humans, copper helped the early humans emerge from the Stone Age. AIt was a crucial component of the creation of bronze and it played a major role in the ...
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 ...
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 .
Chemical studies have been carried out on coal samples from Maiganga coal mine, Gombe formation, Upper Benue Trough of Nigeria with a view to determine theirchemical characteristics and possible utilization as coking coal or otherwise. The coal samples used for the analyses were sourced from the Maiganga coal mine. Various conventional coal analytical methods were adopted according to the ...
CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The impact of water in surface and underground mining activities is of great concern to Mining Engineers and Geoscientists to the effect that its accumulation in excess quantity can render mining of minerals ineffective. Surface and underground mines must therefore constantly be dewatered in order to forestall over ...
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.
