Study these exposures to be able to unravel the Geologic history of the area III. The Mandara Mountains are a mass of basement complex exposure while the Biu Plateau is of basalt. It usually foliated with bands of granular minerals commonly quartz and feldspar alternate with bands of flaky or elongate minerals e. Formation of coal is in stages: The southern part of the Benue Trough which occupies most of the eastern part of the country is filled with Cretaceous to Quaternary sediments.

TheMamu Formation occurs as a narrow strip trending north—south from the Calabar Flank, swinging west around the Ankpa plateau and terminating at Idah near the River Niger. I the relatively warm and moist tropical marine mass which originates over the Atlantic Ocean and is associated with Southwest winds in Nigeria, and II the relatively cool, dry and relatively stable tropical continental air mass that originates from the Sahara Desert and is associated with the dry, cool and dusty North-East Trades harmattan.

Drilling pipes were studied. These are thought to have been depositied in a braided alluvial fan setting. The marine inundatio ns appear to have continued throughout the period of deposition of nigera Agbaja ironstones in the southern Bida Basin Ladipo et al. The formation is entirely marine and has its type locality at Nafada village on the Gombe — Ashaka road.

This stratigraphic dating was obtained from the results of palynological studies by Jan du Chene et al. It is lithologically characterized by ferruginized sandstones, red, loose sands, flaggy mudstones, clays and claystones.

These rocks are invariably interbanded with the oxide iron formation. The schist belts geoloyg been mapped and studied in detail in ,ogbe following localities: The Niger Delta Basin 2. Most of the Benue brine-fields are underlain by formations of Cretaceous age.

Mineralized pegmatites consist of quartz, potash feldspar, albite, muscovite and less commonly, biotite and a range of accessory minerals including tourmaline and economically important cassiterite and columbo-tantalite. There is a channel which prevents the flow of water from the channel. Late tectonic emplacement of granites and granodiorites and associated contact metamorphism accompanied the end stages of this last deformation.

When they cross-cut basement, bt could be used to infer relative age of metamorphic structures and rock suites and could also suggest the existence of older basement windows in the Nigerian schist belts, apart from the immense guide they provide in sampling for isotope geochemistry, analysis and interpretation Dada, Your list has reached the maximum number of items.

The sedimentary rock in this area is sandstone. It is noteworthy that the Sokoto Basin is the southern extension of the Iullemmeden Basin, a sedimenta r y basin which also contains the uranium producing Agades sandstones of the Niger Republic. Soils in this zone are derived from Aeolian sand and are often young soils Entisols.

In Dauda village in Makurid, the sandstone is exposed. Similar shales also occur within units of the Bima Sandstone that outcrop extensively on the Lamurde anticline 2 km to the town of Lafiya, on the Gombe — Numan road. Abundant ignimbrites deposited from ash flows dominate the volcanics with only minor rhyolitic and thin basic flows. Offshore, a 1, m thick sequence consisting of sandstones followed kogge black fossiliferous shales towards the top has been reported.


The units of these steps are the depobelts. Some may include fragments of ocean floor material from small back-arc basins.

Generally the delta prograded over the subsidizing continental-oceanic lithospheric transition zone, and during the Oligocene spread onto oceanic crust of the Gulf of Guinea Adesida et al. Most of the area lies between to m however the Idanre Hills, where the Plateau is highest are about 1 m above sea level Iloeje, Post deformational sedimentation in the Lower Benue Bh, therefore, constitutes the Anambra Basin. The associated intrusives are distributed from Ishiagu in the southeast to as far north as Dadiya, in the northeast, a distance of about km.

Most of the known major occurrences of sandstone type uranium deposits in the world are of Carbonaceous or younger age, although some few deposits of the tectolithologic type, such as the Athabasca deposits Canadaalso occur in the Proterozoic.

The occurrences of the brines are in form of springs, dug-holes and salt ponds, which had been used for ages as the main raw material for local salt production within the associated communities. Only abouttonnes per year are exported, mainly to Ghana. The importance of barytes in the oil, paint and paper industries is well known.

This formatio n consists of sandstones, siltstones, claystones and shales interbedded with bioturbated ironstones.
