Publication Title Sub-surface Geology And Groundwater Distribution Pattern In Lagos Island Environs, South Western Nigeria.
Publication Authors P.S. Ola, O.M. Bankole and A.Y.B. Anifowose,
Year Published 2010
Abstract

Salt-water intrusion was reported to be prevalent in some parts of Lagos Island. To address
this problem, sub-surface geological mapping of the affected area was carried out using
gamma ray and resistivity logs, ditch cutting samples, and geophysical logs of some existing
wells in the area. The work aimed at determining the probable origin of saline water as well
as assessing the depth to the saline/fresh water interface. The suite of logs used facilitated the
delineation of the aquifers and the saline/brackish and fresh water interfaces. A complex
lithology of alternating sequence of sand and clay deposits was observed up to a depth of
about 270m. Also, seven aquifer horizons were delineated. The depths ranges to the tops of
these aquifers are: 3-10m; 40-70m; 60-100m; 110-140m; 150-180m; 178-210m and 212-
240m, corresponding to aquifer thicknesses of 15-25m, 15-30m; 10-45m; 20-40m; 10-42m;
10-30m and 20-45m respectively. It is also observed that brackish/saline water occurrence is
a major feature of the first four aquifer horizons; this implies that freshwater can only be
encountered below 126m, unlike on the Lagos mainland where fresh water is encountered
first and at a shallower depth. While it is apparent that the aquifers are highly susceptible to
salt-water pollution, anthropogenic and biogenic influences, however, water contained in the
upper four aquifers are probably lagoonal in origin and must have retained the salinity that
characterized lagoonal environment, while water in the last three aquifers are of fluvial
origin.

Abstract

A geophysical study of Iwaraja segment of Ifewara-Zungeru fault zone in Nigeria was conducted using remote sensing and geoelectric techniques to analyse and identify the structural elements and fractures. The Omo Forest Reserve area, Abata Egba (along Ondo-Ife highway), and Iwaraja fault zones were selected for the study. Wenner electrode profiling was undertaken at electrode separations of 10, 20 and 30 m on diplines perpendicul-ar to trend of the fault, while Schlumberger electrode configuration was adopted for vertical electrical sounding on points delineated by resistivity profiles. At Omo Forest Reserve, 3 fault signatures of falling resistivity profi-les in uniformly high resistivity environment were identified. Deep fracturing manifested in consistently decrea-sing resistivity values at large electrode separations. At Olode area, 4 signatures were identified. The profiles at Iwaraja area showed the net resistivity decreased in Western direction. The overburden materials were variably thick and underlain by bedrock that had been partially weathered and fractured, but were not infinitely resistive as usually observed in crystalline Precambrian basement complex environment. The study area was characteriz-ed by a series of faults, which were oriented in the North North East - South South West ((NNE-SSW) directio-ns, and inclined towards the East.

Publication Title Talus Caves: Geotourist Attractions Formed By Spheroidal And Exfoliation Weathering On Akure-Ado Inselbergs, Southwestern Nigeria.
Publication Authors KOLAWOLE, F. and ANIFOWOSE, A.Y.B.
Year Published 2011
Abstract

Spheroidal weathering of granites in Akure-Ado axis have resulted in the formation of talus caves as well as smooth rock boulders which are dramatically arranged, thereby giving the formation an overall aesthetic value to the observer. Unique talus boulders exist in Akure inselbergs, southern margin of the Ikere-Ado batholith. This paper looks at the uniqueness of these formations as well as their economic potentials for leisure and recreation purposes. Much attention has been given to Olumo Rock in Abeokuta, Riyom Rock and the Shere Hills both in Jos Plateau. With the clamour for developing other sources of revenue beside oil, the Akure-Ado inselbergs require attention toward proper development and packaging as potential tourist sites with the aim of enlarging the nation’s reserve of tourism products as they will draw local as well as international tourist traffic.

Publication Title Integrated Remote Sensing And Geophysical Investigations Of The Geodynamic Activities At Lake Magadi, Southern Kenyan Rift
Publication Authors Komolafe, A.A., Kuria, Z., Woldai, T., Noomen, M. and Anifowose, A.Y.B.
Year Published 2012
Abstract

 

The tectonic lineaments and thermal structure of Lake Magadi, southern Kenyan rift system, were investigated using ASTER data and geophysical methods. Five N-S faults close to known hot springs were identified for geoelectric ground investigation. Aeromagnetic data were employed to further probe faults at greater depths and determine the Curie-point depth. Results indicate a funnel-shaped fluid-filled (mostly saline hydrothermal) zone with relatively low resistivity values of less than 1 Ω -m, separated by resistive structures to the west and east, to a depth of 75m along the resistivity profiles. There was evidence of saline hydrothermal fluid flow toward the surface through the fault splays. The observed faults extend from the surface to a depth of 7.5 km and are probably the ones that bound the graben laterally. They serve as major conduits for the upward heat flux in the study area. The aeromagnetics spectral analysis also revealed heat source emplacement at a depth of about 12 km. The relative shallowness implies a high geothermal gradient evidenced in the surface manifestations of hot springs along the lake margins. Correlation of the heat source with the hypocenters showed that the seismogenetic zone exists directly above the magmatic intrusion, forming the commencement of geodynamic activities.

Publication Title Emplacement Tectonics Of Idanre Batholith, West Africa.
Publication Authors Anifowose, A.Y.B. and Kolawole, F.
Year Published 2012
Abstract

Evaluation of the length and orientation of the lineaments within Idanre area indicated that the dominant trend is ENE-WSW (80°– 90°) – oblique to the long-axis of the batholith; while another is at NNWSSE (170°-180°) and NNE-SSW (0°-10°) - parallel to the long-axis of the batholith. The ENE-WSW fractures represent those that developed due to shrinkage within the cooling batholith as the magma rose, while the other group (NNW-SSE and NNE-SSW) represents zones of weaknesses within the country rock at the time of intrusion of the magma. The results showed high density fracturing on the batholith, which is possibly related not only to its depth of emplacement but also to shrinkage effects due to compressive forces acting on the intrusive body at the time of its ascent. Also, the parallelism of some of the fractures with the long-axis of the batholith seems to indicate the influence of pre-existing zones of weaknesses in determining the tectonic grains of the batholith. The intrusion is fault-bounded and its fractures are very deep and they cut the batholith into massive, steep sided and dome-shaped inselbergs. They are conduits through which ore-bearing fluids can be channeled to the surface. It can therefore be concluded that a need for detailed exploration particularly along the fractures is necessary.

Publication Title Remote Sensing Analysis Of A Dextral Discontinuity Along Ifewara-Zungeru Area, Nigeria, West Africa.
Publication Authors Kolawole, F. and Anifowose, A.Y.B.
Year Published 2011
Abstract

 

The Ifewara-Zungeru megastructure is an over 550 - km long NNE-SSW trending fault stretching from the south just east of Ijebu Ode, through Ifewara and Okemesi to the southwestern edge of the River Niger around Lafiagi. It reappears beneath the sediments of the Nupe Basin and extends northeastwards for over 300 km, through Zungeru to Kalangai. Detailed remote-sensing mapping of the lateral extent of this suspected shear zone using satellite imagery field mapping ground-truthing survey was carried out. Structural analysis of the fault system was done across the entire area that was traversed.The results obtained from this investigation revealed that satellite imagery study of a segment of the megastructure shows a ductile dextral fault zone with a drag towards the NNW direction in Zungeru area. Highlevel folding of meta-sediments exist within the area with directions almost perpendicular to the general NNE-SSWtrend of the host rocks. This faulting caused a measure of morphostructural reorientation of the mylonites and enclosing schistose rocks.

Publication Title Tectono-Hydrological Study Of Akure Metropolis, Southwestern Nigeria
Publication Authors A.Y.B. Anifowose and F. Kolawole
Year Published 2012
Abstract

An integrated approach was applied in studying the tectonics and their hydrological implications in Akure metropolis, using remote sensing, structures and secondary geophysical information. Structural geological information was extracted from Landsat ETM+ imagery covering Akure area. Since the study area is densely built-up, a systematic approach was employed in delineating the fractures which are characteristic of the underlying Basement Complex geology. Based on the fact that drainage system on such terrain is structurally controlled, the lineament trends on the few rock outcrops observable on satellite imagery were correlated with the trends of rivers draining the area. Results highlight specific fracture pattern that is most probable for hydrogeological exploration. The influence of tectonism in defining the basement aquifers underlying the study area as well as their implications for hydrological hazards were also underscored.
The methodology adopted in this study may be used for hydrogeological exploration in urban areas underlain by Basement rocks in view of the challenge encountered in lineament detection in built-up areas.

Publication Title Waste Disposal Site Selection Using Remote Sensing And GIS: A Study Of Akure And Its Environs, Southwest-Nigeria
Publication Authors A.Y.B. Anifowose, K.E. Omole and O. Akingbade
Year Published 2011
Abstract

Waste disposal has been a serious challenge in Nigerian cities especially as rural-urban
migration intensifies. While overwhelming scientific evidences abound that global warming is
taking a significant toll on the Earth and its occupants, Nigeria is striving to join other countries in mitigating the effects. One way of intensifying the mitigation is through appropriate and environmentally-friendly waste disposal and management. All manners of wastes are usually disposed of without any serious consideration for the environment. Open incineration is a very common means of waste disposal in developing countries. In spite of the meager contributions of this group of nations to industrial growth, open incineration method of waste disposal hugely adds to the problem of climate change. It has been observed that there is the tendency to dispose wastes indiscriminately and in an uncoordinated manner, thereby resulting in unhealthy environment. In this study, a satellite imagery covering Akure and its environs was analysed using ArcView GIS 3.2a to develop a user interface for selecting a waste disposal site with special emphasis on geologically suitable conditions. This study aims at demonstrating the potential and efficiency of using GIS in selecting sites for the storage of biodegradable solid wastes. Results show suitable areas where landfill sites can be safely and aesthetically located within the study area, putting urban growth rate into consideration.

Publication Authors Awoniran, D.R., Adewole, B.M., Adegboyega, S.A. and Anifowose, A.Y.B.
Year Published 2014
Abstract

This study investigates the pattern of land use/land cover change in the Lower Ogun River Basin
between 1984 and 2012. Two sets of topographical maps, a Landsat-5 TM image of 1984, Landsat-7
ETM+ of 2000 and a Google Earth image of 2012 were used for the study. The topographical maps and
satellite images were digitally processed using ILWIS 3.2™ software and exported to ArcGIS 9.3™ for
further processing and analysis. The processed images were subsequently classified using the
maximum likelihood classification algorithm, resulting in the identification of seven land use classes.
Furthermore, change detection analysis was carried out using Cross Module in ILWIS™. The result of
the change detection analysis indicated that between 1984 and 2000, 80.08% of the land cover in the
study area has been converted to other land uses while only 19.92% remained unchanged. Also, within
the same period, light forests, non-forested wetlands and forested wetlands decreased at average
annual rates of 8.26, 4.66 and 2.81%, respectively, while water bodies also decreased at an annual rate
of 0.17%. On the other hand, farmland, shrubs and urban/built-up areas expanded at average annual
rates of 7.23, 6.74 and 4.65%, respectively. The result further indicates that between 2000 and 2012,
49.86% of the land cover has been converted to other land uses, while 50.14% remained unchanged, and
that farmlands, shrubs, urban/built-up areas and forested wetlands expanded at average annual rates of
6.01, 1.95, 0.89 and 0.17%, respectively, just as light forests, non-forested wetlands and water bodies
decreased annually by 8.26, 2.70 and 1.40%, respectively. Five randomly collected soil samples were
analyzed for their physicochemical properties. Findings show the growing impact of urban agriculture
on wetland ecosystem within the study area, manifesting in soil degradation and biodiversity loss. The
implication of these findings is that the area is susceptible to devastating flooding which can culminate
in the loss of lives and properties. This study recommends the development of effective land
management information system and policies that will ensure sustainable management of fragile
ecosystem.

Publication Authors E.Y. Yenne, A.Y.B. Anifowose, H.U. Dibal and R.N. Nimchak
Year Published 2015
Abstract

The study area is a basement complex environment with its associated difficulties in groundwater supply as a result of lateral discontinuity in basement lithologies. This study assessed and established the
relationships that exist between lineaments and borehole yields. Five Hundred and thirteen (513) lineaments were extracted and analyzed from remote sensing data obtained from global land cover facilities of which several lineament maps were generated using ArcGIS® software. Twenty seven (27) yield data were interpreted, correlated and evaluated with the produced lineaments. Results indicated three (3) categories of yields exist in the study area: low yields (<0.2 l/s), moderate yields (0.5 -1.0 l/s) and high yields (>1.0 l/s). Thus, the high yielding boreholes are found at the center of the study area where lineament density is high. Further analyses carried out show that the productivity of a borehole is strongly affected by its closeness to an extensional lineament but insignificantly influenced by its closeness to a lineament intersection points in the area. The study also indicated that the presence of thick overburden to bedrock is also a key factor in controlling groundwater productivity.

Abstract

 The significance of air pollution as one of the contemporary issues and accelerating factors that propel
climate change in both developed and developing countries cannot be overemphasized. The problem of
air pollution has seemingly become intractable with the incessant failure of both global and local
environmental policies purportedly emplaced to address its devastating trend, particularly in growing
megacities of the world. The devastating effects of the phenomenon are more pronounced in megacities
of developing countries than in developed ones. Lagos, as an industrialized, commercialized and an
emerging megacity in Nigeria, has been subjected to several predictions of the negative impacts of
changing climatic conditions partly caused by ubiquitous air pollution. Efforts at stemming the tide of the
increasing challenges of air pollution worldwide has significantly been thwarted by inadequate funding,
hence the need to review the literature on the environmental implications of growing air pollution, its
contributions to climate change and its negative impacts on the lives and properties of teeming
inhabitants of Lagos. A review like this will provide a synthesis of knowledge and information on
mitigative and adaptive measures that can be adopted to minimize the impacts of air pollution on the
mega city.This study utilizes consciously selected and current literatures on the subject matter and found
that Lagos inhabitants have been vulnerable to virtually all forms of damaging effects of climate change
majorly propelled by seemingly uncontrollable air pollution. This implies that the situation requires
proactive measures, otherwise, avoidable loss of lives and large scale destruction of properties may be
inevitable. The paper therefore advocates involvement of all stakeholders in both mitigation and
adaptation measures to climate change through enhancement of indigenous knowledge and creation of
awareness among citizens about the need to be conscious of their carbon foot prints.

Year Published 2014
Abstract

The Idanre Hills comprise many elongate, steep sided, and dome-shaped porphyritic granite inselbergs with an average elevation of about 3,000m asl. The area is part of the many batholiths and stocks which intruded preexisting metasediments during the Pan African Orogeny (550±50 Ma). Apart from the existence of massive rock outcropsfield studies indicate the occurrence of minor intrusions and fractures on both mega- and mesoscales. The district has been regarded as attractive to tourists more for the Orosun festival celebrated as part of the residents’ heritage than for the geology and landscape. The former is the reason for efforts at listing the Idanre Hills among UNESCO’s World Heritage Sites. In the rich tourist potential of the hills, 16 geoheritage sites were listed and evaluated based on previously studied sites of geological and geomorphological value. The assessment showed only 10 of them to be of significant geotouristic value representing 8 out of 15 thematic groups. These identfied geosites and geomorphosites have been described in this paper. Infrastructural facilities such as a balustraded stairway, rest points, pipe-borne water, and chalets had earlier beeprovided to attract tourists to some parts of the hilltops. Nevertheless, the development and effective management of the Idanre Hills’ geologic landmarks as tourism and educational resource have the ability to improve the local economy through job creation and revenue generation, as well as attracmore local and, especially, international tourists to the site.

Abstract

Petrochemical-induced groundwater contamination was investigated using an integrated GIS and physico-chemical properties of sampled hand-dug wells close to fuel stations in Ile-Ife, Southwestern Nigeria. This was with a view to evaluating the influence of hydrocarbon spills on groundwater resources within the vicinity of the supposedly leaking underground fuel tanks. Topographic map and IKONOS image of the study area were acquired. Samples from forty-two (42) fuel stations and thirty (30) hand-dug  water wells were analyzed for organic compounds such as benzene, ethylbenzene, toluene, xylene, and 1,2,4 trimethylbenzene using gas chromatography and mass spectrometry. Geographic Information System (GIS) tools were employed to examine the spatial relationships between the contaminants and to characterize their levels within the study area. Spatial analysis operations such as spatial interpolation, raster based reclassification, buffering and map overlay were employed. The results obtained were compared with World Health Organization (WHO) standards. Results indicate the presence of benzene in all the water wells with concentrations ranging from 0.004 to 0.09 mg/l; pH, ethylbenzene, toluene, xylene and trimethylbenzene have their highest values at 7.5, 0.074mg/l, 0.031 mg/l, 0.048 mg/l and 0.062 mg/l respectively, while the electrical conductivity varies between 64 and 1538 µS/cm. Contaminations from these petrochemical components were evident throughout the study area; of most significance is the increasing concentration level of benzene and electrical conductivity which exceeded the WHO standard. Obafemi Awolowo University (OAU) Campus, though not host to many fuel stations, appeared to contain moderately high levels of the organic compounds, which can be attributed to the improper disposal of chemicals used in laboratory experiments, and leakages from underground fuel storage tank in the Power House. The study concluded that most of the hand-dug wells close to fuel stations in Ile-Ife, Southwestern Nigeria are contaminated.
