    Geotourism 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.

    Exploration for iron ore in Agbado-Okudu, Kogi State, Nigeria

    This report details the result of geophysical exploration for iron ore; which involved vertical magnetic intensity (∆Z) and gravity measurements, to delineate the geometry and depth extent of the deposit and acquiring quantitative and qualitative information for pre-drilling purposes in Agbado-Okudu. It is located about 3 km from Jakura along Lokoja-Jakura marble quarry and within low latitude precambrian basement complex district of Kogi State, Nigeria. A total of 517 magnetic measurement points along 16 traverses and 330 gravity reading along 11 profiles on the deposit in northeast–southwest azimuth were undertaken. The magnetic and gravity data enhancement involved linear regression curve fitting and fast Fourier transform, which were used to construct residual magnetic (RM) and gravity (RG) anomalies, analytic signal amplitude, Euler deconvolution at varying spectral indices (SI), power spectrum, and source parameter image (SPI), using the submenu of Geosoft Oasis Montaj software. Interpretation of the RM and RG anomalies revealed a primary causative body which perfectly correlates the positive anomalies and iron ore deposit, in form of a horizontal or gently dipping dyke with strike length of 600 m and average width of 110–130 m, within the gneiss complex in the north and trending south of the area. A secondary causative body associated with the negative anomalies and inferred as a vertical/near vertical thin sheet striking northeast–southwest coincided with the granitic and quartzitic intrusion. The NW–SE and E–W lineament trend conformed Kibarian and Liberian orogeny cycles of generally known structural trends in Nigeria, which shows that the iron ore deposit is structurally controlled. Depths to sources were estimated within range ≤ 2–24 m and 37.5–60 m, regarded as shallow and relatively deep depths, respectively. Ten vertical boreholes ranging in depth between 50 and 100 m are recommended, five of which require a priority attention to ascertain the thickness of the primary causative body.
