The kobe occurrence of Foveotriletes margaritae pollen and the dinoflagellate Svalbardella sp. The Yola Sub Basin 2. Oyenuga reported that the humid, tropical forest zone of the south that has longer rains is capable of supporting a number of plantation crops such as cocoa, oil palm, rubber, coffee, cotton and staple crops like, yam, cassava, cocoyam, sweet potatoes, melon, groundnut, rice maize and cowpeas.
Geology of Nigeria
Coal beds are usually found with shales and fine grained sandstones. In that study, it was observed that the Ise, Nlgeria and Abeokuta formations have similar litholo gic and electric log characters.
Fracturing and jointing are intense in the areas of mineralization. Shales of the Mamu Formation on the south side of the Anambra Basin are commonly interbedded with chamositic carbonates and overlain by bioturbated siltstones, sandstones and coal units in coarsening upward cycles towards the north side of the basin Akande et al.
Schist Belts Metasedimentary and Metavolcanic rocks: It can also occur at near surface. The coal measure of the Lafia formation is brick red, with small quatity of sand and clay.
The reported occurrence of the foraminifera Eponides pseudoelevatus Graham et al. The basal conglomerates have beology reported from outcrops and boreholes Jones and Hockey, ; Omatsola and Adegoke, The anomalies in the formation occur along a belt stretching from Okigwe in the south to Angba about km away in the north. In the Paleocene, the marine shales of the Imo and Nsukka Formations nigfria deposited, overlain by the tidal Nanka Sandstone of Eocene age.
It has a heterogeneous assemblage comprising migmatites, orthogneises, paragneisses, and a series of basic and ultrabasic metamorphosed rocks. It has a four nieria line which consist of a conveyor belt which carries raw materials to and fro the quarry.
It is logical to include the Anambra Basin in the Benue Trough, being a related structure that developed after the compressional stage Akande and Erdtmann, The nigerla analogy in time with the development of the Birrimian of the West African Craton is striking.
This is overlain by the alternating shales, siltstones, claystones and sandstones of the Patti Formation ca. In most of the communities, it is only women-folk that have access to the saline waters while non-indigenes or men are either totally not allowed or allowed only after an initial traditional ritual.
TheMamu Formation occurs as a narrow strip trending north—south from the Calabar Flank, swinging west around the Ankpa plateau bh terminating at Idah near the River Geoology. These soil types vary in their potential for agricultural use. A comparison of the sediment thicknesses in the two basins indicate that the successions of the Anambra Basin reached up to 8 km thickness compared with an average of 3. Drilling pipes were studied. Its typical jogbe occur around the town of Awe, where Offodile estimated the thickness to be about m.
Iron concretions are observed to be imbedded in the rock and is circular in shape. They are the oxide, silicate and sulphide facies. In all, about 20 veins have been mapped in Azara, most of them represented by narrow, winding structures.
This is expected because the degree of available moisture in the soil is an important factor in soil reactions and fertility and productivity. The reddish colour goelogy due to iron enrichment.
It usually foliated with bands of granular minerals commonly quartz and feldspar alternate with bands of flaky or elongate minerals e. The more marine influences in the adjacent Anamb ra Basin is probably related to the nearness of that basin to the Cretaceous Atlantic Ocean prior to the growth of the Niger Delta.

In building, it is used for building bricks, vitrified and enameled bricks, tiles for floors, roofs, walls and drains, sewer pipes and as an ingredient of cement. This study investigated the cause of identified zones of overpressure in some selected wells in a field in the Niger Delta sedimentary basin. He considered the hypersthene diorite as older than the granites from contact relations.
Formations was therefore discontinued and replaced by the Abeokuta Formation which has priority of publication and a wider accepted usage. It is almost always accompanied in its ores by varying amounts of the related elements tantalum. The Abeokuta Formation was defined by Jones and Hockey to consist of grits, loose sand, sandstone, kaolinitic clay and shale.
Pebbles which are sub-angular to rounded are found area the outcrop. The E-mail Address es you entered is are not in a valid format.
