The geology of southern Akor and its environs lies within the Oban Massif, a component of the crystalline basement of Nigeria. The Nigeria crystalline basement in turn forms a part of the African crystalline basement and covers over 50% of the total land surface of Nigeria . The rock assemblages encountered and identified consists of mainly schists, gneisses, Amphibolite, Charnockite, Marble and Quartzites and pegmatite, Quartz vein and Aplite emerging as Igneous intrusive rocks. The area mapped... read more

Heavy metals pollution of aquatic ecosystem is becoming a potential global problem, pollution typically refers to chemicals or other substance in concentration greater than it would occur under natural conditions. Water pollution is the introduction by man of substances into the aquatic environment resulting from deleterious effect as harm to human health (FAO 1990).The presence of increased level of heavy metals in the aquatic environment has been of much concern for the past decades due to adv... read more

Subsurface maps are perhaps the most important vehicle used to explore for undiscovered hydrocarbons and to develop proven hydrocarbon reserves. However, the subject of subsurface mapping is probably the least discussed of interpretation and the construction of structure/Isopach maps, yet most important aspect of petroleum exploration and development. As a field developed from its initial discovery, a large volume of well, seismic and production data are obtained. With these data, the accuracy o... read more

The resistivity method is used in the study of the horizontal and vertical discontinuities in the electrical properties of the ground and also in the detection of three dimensional bodies of anomalous electrical conductivity. In the study of ground water movement in obubra area, the the resistivity method commonly employed are the electrical resistivity method. Electrical resistivity method is one of the most useful techniques in groundwater geophysical exploration, because the resistivity of r... read more

liciclastic rocks (e.g., Dickinson and Suczek, 1979; Bhatia, 1983; Bhatia and Crook, 1986; Roser and Korsch 1986; McLennan and Taylor, 1991). Among the terrigenous sedimentary rocks, shales are considered to represent the average crustal composition of the provenance much better than any other siliclastic rocks (e.g., McCulloch and Wasserburg, 1978). Shales retain most of the mineral constituents of the source and their bulk chemistry preserves the near-original signature of the provenance and m... read more

1.0-6.0) in borehole and, (21.0-35.6) well water; BOD (<0.50) borehole and, (56.0-185) well water. Micro-biological parameters; TC (cfu/100ml) were not present in either of the ground water. All values were related to WHO, EPA and FMA standard of water quality. Hence it was therefore recommended that almost all the parameter analyzed for were of the standard of WHO, EPA and FMA which is portable for domestic uses, also with no health implication, except for BOD in well water which was above the ... read more

There is a great need to examine the effects of soil erosion on settlement in Agbor, Delta State-Nigeria. This study will help to know if there is any significant relationship between the effects of soil erosion and the level of settlement development in the study area. The researcher is interested whether soil erosion has significant effect on the settlement of Agbor. The study will also look at the factors responsible for the degradation of the natural environment especially in Agbor, Delta St... read more

Ogbe-Ijaw lies within latitude 50521N and 50451N of the equator and longitude 50751E and 50311E of the Greenwich meridian. From West to South, the area is wrapped by the Forcadoes on the west, Warri South L.G.A on the east, Burutu L.G.A on the South and Warri North L.G.A on the north. Ogbe-Ijaw has an estimated population of over 116,000 people (NPC, 2006). The location and size of the study area is such that favours oil exploitation activities and man has through his various human and anthropog... read more

River Ethiope which cuts across the two study areas (Abraka and Eku) took its source from Umuaja in Ukwuani L.G.A Delta State. River Ethiope is located in the South-South geo-political zone of Southern Nigeria. Abraka is located geographically at latitudes 050 451 to 050 501 North of the equator and longitudes 060 001 to 060 151 East of the Greenwich Meridian. Abraka is situated at the Eastern Bank of River Ethiope in Ethiope East Local Government Area of Delta State in the Niger Delta region of... read more

The importance of this study is that it will provide us with the opportunity of studying oil exploration in Ughelli and Warri; and the major areas in Nigeria especially in the study areas seriously affected by crude oil exploitation; and take a deeper look at the effects of oil exploration on the inhabitants of Ughelli and Warri and proffer solutions to the problems identified because if problems are not properly looked into and controlled, the situation could get out of hand and this will not b... read more

he study area lies within the Guinea Savannah vegetation belt characterized by short trees and tall grasses. The vegetation here is prominently made up of sparsely distributed trees, herbs, shrubs, and grasses. The trees (mango and orange) help check the activities of erosion. Trees in this area are mostly concentrated along fracture zones within the plutonic bodies and on the Quartzite ridges were adequate soil cover has resulted and there is adequate groundwater retention. The vegetati... read more

In carrying out data analysis, it is of uttermost importance to identify outlying observations that deviates so much from the overall datasets before data modelling; otherwise aberrant data may result in model misspecification, biased parameter estimation and incorrect results. That is to say it is futile to do data based analysis when data are contaminated with outliers because outliers can lead to incorrect analysis of results. Outliers are observations that do not follow the statistical d... read more

In Nigeria and particularly in Zaria city of Kaduna state, open dumping is still the most common household waste disposal method/practice. This type of practice is un hygienic and environmentally unfriendly. This research is aimed at effective household waste management practices in the study area. The research found that there are some other types of management or disposal method in practice in the study area, these include the use of packing and burning, dumping in pits outside the house and d... read more

The high concentration of oil in accidental spills represents a serious environmental threat, until the oil is diluted and/or degraded. Low temperature, ice and lack of infrastructure will generally make the impact of oil spills in the Arctic longer lasting than at lower latitudes. The spreading, fate and impact of oil spilled in different habitats differ, with the marine spill having the potential to impact large areas and resources far away from the spill site, while terrestrial spill are gene... read more
