Laterite is a highly weathered material, rich in secondary oxides of iron, aluminum, or both. Geotechnical investigation is one of the effective means of detecting and solving pre, syn and post constructional problems. The geotechnical properties of lateritic soils and their suitability for road construction have been evaluated for selected sites in Minna, North-central Nigeria.
Petrographic studies on Granitoids from Katchuan Irruan and adjoining areas, southeastern Nigeria, has shown that they are garnetiferous biotite granite, aplitic granite, porphyritic hornblende biotite granite, porphyritic muscovite biotite granite, weakly foliated leucogranodiorite and simple pegmatite. They are closely associated with the Precambrian Basement Complex rocks which …
within the rest of the Precambrian rocks in Nigeria, he grouped the rocks in this region as migmatite – gneiss complex comprising largely of sedimentary series with associated minor igneous rock intrusions which have been altered by metamorphic, migmatitic and granitic processes. Odeyemi (1999) suggested

Abrasivity Indexes. Methods of calculating the overall abrasiveness of rock are based on determining the quantitative mineralogical composition of the rock and combining this with known values of the hardness of the individual minerals (West 1981).Thus, by employing different mineral hardness scales existing in the literature, it is possible to derive various theoretical rock hardness indexes.
Nigeria's Sokoto Basin represents the southeastern part of the Iullemmeden basin, which stretches across parts of Mali, Niger, Benin and into northwest Nigeria. The Tertiary rocks of the Sokoto Basin are mostly interbedded sandstones, clay and some limestone (Pavelic et al. 2012).
broken up by the Older Granite (Wright and McCurry, 1970). III. SITE DESCRIPTION The study area is bounded approximately by longitudes 70 36'E and 70 38'E, latitudes 110 09'N and 110 11'N as shown in location map (Fig 1) with an average elevation of 685m above sea level. The area falls within the semi-arid zone of Nigeria (Harold, 1970).
The Tuareg shield is the southern prolongation of the Pan-African mobile belt (Trompette, 1980). The Gwon-Gwon pegmatite at Wamba, is the third mineralized pegmatite field in Nigeria (others being at Egbe, Ijero) but the first mineralized in northern Nigeria. The second in the north being the Jema'a pegmatite (Matheis and Cean-Vanchette, 1983).
1.4 Minerals and Rocks. The rest of this chapter is devoted to a brief overview of a few of the important aspects of physical geology, starting with minerals and rocks. This is followed by a review of Earth's internal structure and the processes of plate tectonics, and an explanation of geological time. Like everything else in the universe ...
Nigeria is situated within the Pan African mobile belt and sandwiched between the West African Craton to the west, the Taureq Shield to the north and the Congo Craton to the southeast (Fig. 1). About half of the total area of Nigeria landmass is underlain by rocks of the Precambrian age known in the country as the Basement Complex.
Literature Review General: I referred various technical research papers on assessment of ground water quality for bore wells of different cities and countries, which are presented in Dissertation Phase-1. Reported work on assessment of ground water quality index is summarized below.
For cadmium, the depletion factor, average terrestrial granitics/14321g, is roughly 6, although in this case there is considerable overlap with the terrestrial range, and the comparison suffers from a paucity of data, and a need to weed out much data of more-or-less manifest unreliability, for Cd in terrestrial rocks.
Literature Review Of The Area In basement provinces groundwater occurrence depend exclusively on discontinuities like fractures, joints, fissures, and weathered litho – zones. The fissures of crystalline rocks are limited to shallow depths, and water movement is lateral in the direction of the gradient downwards to the drainage area.
The pre- to post-Late Neoproterozoic geological histories in the south to southwestern part of Mamfe Basin (SW Cameroon) were reported following analysis of the zircon crystals from their host rocks. A genetic model was developed for the zircon host rocks' formation conditions, and the registered post-emplacement events were presented. The obtained ages were correlated with the data ...

1.5 Literature Review The Basement Complex rocks in the study area have received very little attention from researchers as evidenced in literature. Much of the information on the area is contained in Geological Maps of Nigeria produced by the Geological Survey of Nigeria (Okezie, 1974,

The discovery of certain granites, relatively rich in uranium, in Nigeria (Beer, K, E., 1952) and the fact that many of the intrusive rocks of New England bear many points of resemblance to the rocks of Nigeria, (Billings and Keevil, 1946) lead to the inception of this study.

basement complex rocks are thought to be Precambrian. The studied area lies between latitude 12.4" and 11.11"W and longitude 13.81" and 14.13" S. The studied area is underlain by Precambrian basement complex of southern western Nigeria .The major rock in the area is …
charnockitic, gabbroic and dioritic rocks; members of the Older Granite suite, mainly granite, granodiorites and syenites. Dolerite dykes are also common in the area (Rahaman 1976). The meta-sedimentry rocks such as quartzites and marble are found associated with belts of slightly migmatised to unsigmatised paraschists and meta-igneous rocks.

The geology of the Komu area, south-western Nigeria was investigated in order to determine the nature of occurrence, petrography and chemical composition, and to evaluate the mineral potential of granitic pegmatites. The pegmatites are hosted by para-gneisses, amphibolites and granitic rocks.

The granitic rocks tend to be massive (non-foliated). Both the metamorphics and granitics tend to be pervasively fractured with multiple intersecting joint sets. Both small and major faults are common; a few, particularly in Summit-Lake Counties and along the west side of the Sangre de Cristo Mountains have been active in the Quaternary Period.
