- ItemEvaluation of Geotourism Potential of Eruku and Its Environs: A Case for Ilado Hill(Sustainable Geoscience and Geotourism, 2021-04-30) Olufemi S. BAMIGBOYE; Toba E. BAMIDELE; Shakirat O. MUSTAPHA; Olufemi OLANIYAN; Moses O. AWOJOBIGeotourism potential of Eruku and its environs with emphasis on Ilado hill was appraised.The methods adopted in this work includes geological field mapping and interview. From the field mapping exercise, the rocks in Eruku and its environs include migmatite, gneisses, amphibolite granites, diorite and pegmatite. The tourist attractions include remnant of ancient city wall (Odi Ilu), joining wall (Odi Abumo) and Ilado hill. Ilado hill was also discovered to be an abandoned ancient city with city gate made of gold with full regalia of African administrative offices. The conclusion drawn from this work is that Ilado hill fulfilled all the requirements to be a tourist destination, and hence, it is a good source of recreation while also serving as source of income for the Eruku City and government at large.
- ItemContemporary environmental impact assessment issues in Nigeria(RMZ – M&G, 2013-09-30) Olubunmi Owoyemi and Olufemi BamigboyeFor development to be sustainable it should meet the emerging needs of the present and succeeding generations. It must focus on growth without compromising the needs of the future. Environmental engineering requires that the impact and interaction of common engineered structures such as dams, highways, deep foundation buildings, among others are carried out with minimal environmental deterioration. Agricultural practices, oil exploitation activities, mining operations and industrial waste disposal which affect our environment tremendously, should be subjected to comprehensive and adequate assessment of the impacts they will have on our environment before the implementation of such activities. This will lead to adequate preparation for effective mitigation of future environmental hazards that might accompany these activities.
- ItemIntegrated Geophysical Investigation of Aquifer and Its Groundwater Potential in Camic Garden Estate, Ilorin Metropolis North-Central Basement Complex of Nigeria(IOSR Journal of Applied Geology and Geophysics (IOSR-JAGG), 2019-04-30) Bawallah, M. A., Aina, A.O. , Ozegin, K.O., Akeredolu, B.E. , Bamigboye, O.S. , Olasunkanmi, N.K. , Oyedele, A.AThis paper presents a geophysical study for ground water evaluation in a typical crystalline basement complex terrain of Camic garden estate in Ilorin metropolis, North central basement complex of Nigeria. Very Low Frequency-Electromagnetic (VLF-EM) and Ground Magnetics (GM) were used for structural evaluation/delineation combined with Electrical Resistivity Method (ERM) using the Vertical Electrical Sounding (VES) Technique. Eight (8) VLF-EM and GM profiles covering a distance range of 70 to 300 m were established, VLF-EM at a measuring intervals of 10 m each, while six (6) VES were carried out based on quantitative, semi-quantitative of the VLF-EM and GM, a correlation was also carried out between the VLF-EM and the GM results of conductive zones and zones of low magnetic susceptibility that may be diagnostic of fault, fracture/weathered material. The six (6) VES were carried out using Schlumberger configuration, with AB/2 varying from 1.00 m to 225.00 m, with the predominant curve being of the HA type representing three-layer earth model i.e. the top soil, the clayey/weathered layer, and the fresh basement for most of the curves obtained, the clayey/weathered layer constitutes the major auriferous unit in the area, and are characterised by moderately low resistivity value which ranged between 23.00 and 200.00 Ωm while the thickness varies 13.2 to 61.0 m. The study reveals that 83% of the study area may be of low water bearing/yield owing to the thick clayey column that characterised the weathered layer without fractured basement. Therefore, there is a critical need for elaborate ground water study in the entire area, to be able to site boreholes with a reasonable yield in an environment where fractured basement/bedrock is rare to find.

This activity is being done on different scales such as artisanal/illegal mining, small scale mining and large scale mining. The exploitation of these natural resources has been done in the past (>50 years) using crude tools such as diggers, shovels, hammers with no geological or geophysical survey and environmental impact assessment. The introduction of machines like excavators and payloaders with some geological geophysical and/or geochemical survey without adequate environmental impact assessment characterize the mining business today. Both in the past or in the present, mining has some effects on the environment and these include ecological disturbances, socio-economic effects and pollution.

It also evaluates the likely future effects of mining on the environment. It is recommended that the government should help in creating the enabling environments for the mining business to thrive; remove bottle-necks from procedures in securing the required mining documents by the miners. In addition, miners should be grouped into cooperatives to make for efficient supervision and management. Furthermore, the miners should be effectively educated on the best practices in mining. In conclusion, if all aforementioned are effected, the negative effects of mining on the environment will be greatly reduced.
- ItemAssessing Heavy Metal Contamination in Stream Sediment and Water in Idofian, Kwara State: A Geochemical Perspective(JOURNAL OF SUSTAINABLE NATURAL RESOURCES, 2024-03-31) Bamikole Emmanuel Ayobami, Omolayo Ajoke Omorinoye,Olufemi Sijuade Bamigboye Oniyangi Abdulhameed KayodeEnvironmental geochemistry examines the presence, dispersion, and movement of elements on the Earth's surface. This research explores the environmental geochemistry of the Idofian area in Kwara State, Nigeria, with a particular emphasis on water and stream sediments. The heavy metals were ascertained using X-ray diffraction (XRD) and atomic absorption spectrometer (AAS). The study revealed the presence of marble, diorite, gneiss, pegmatite and amphibolite in the Idofian area. Furthermore, the XRD analysis provided information about the mineral composition including quartz, micas, lepidolite, laumontite, orthoclase, plagioclase, dolomite and anthophyllite. The findings revealed the absence of sediment contamination, while highlighting substantial contamination in the study area's water. This contamination, attributed to a combination of geogenic and anthropogenic factors, underscores the crucial necessity for implementing sustainable management practices in the region.
