Bachelor Thesis from the year 2011 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: A, Abubakar Tafawa Balewa University (FACULTY OF SCIENCE), course: GEOLOGY, language: English, abstract: This work produces some vital geologic information on the geology and structural analysis of rocks mapped around Kanwara, Dass local government area of Bauchi State. The mapped area is located between longitude N10001’09” and N1O000’09”and latitude E9032’42” and E9031’26”. Exposure of rocks in the area were mostly high level and medium level outcrops with only a few low level outcrops, the high level outcrops were conically shaped with height ranging between 400m to 700m above sea level while the inselberg was about 900m. The predominant rock types in the area were granite gneiss, biotite granite and migmatite, under thin section, minerals were identified via their respective optical properties under both plane polarized light and cross polarized light, the major minerals associated with the rocks were; biotite, quartz, feldspars, (orthoclase & plagioclase), muscovite and microcline. Based on field observations, the geologic structures found on the rocks include; joints, foliations, minor folds, ghost schist, dykes and veins. The joints indicate the masking effect of the pan African orogeny on the older granites (trending NW-SE). The shape of the girdle from the structural analysis conducted indicates that the rocks of the mapped area were subjected to medium grade metamorphism.
viii debate of those earlier days has been beautifully summarized by H. H. Read in his famous "Granite Controversy" (1957). Read's formulation of the controversy occurred at the time when geochemistry was as a new and powerful tool. The new techniques opened era during which emerging an granites were considered mainly from this new viewpoint. Geochemical signatures have shown that mantle and crustal origins for granites were both possible, but the debate on how and why granites are emplaced did not progress much. Meanwhile, structural geology was essentially geometrical and mechanistic. In the early 70's, the structural approach began to widen to include solid state physics and fluid dynamics. Detailed structural maps of granitic bodies were again published, mainly in France, and analysed in terms of magmatic and plastic flow. The senior editor of this volume and his students deserve much of the credit for this new development. Via microstructural and petrofabric studies, they were able to discriminate between strain in the presence of residual melt or in the solid-state, and, by systematically measuring magnetic fabrics (AMS), they have been able to map magmatic foliations and lineations in ever finer detail, using the internal markers within granites coming from different tectonic environments. The traditional debate has been shifted anew. The burning question now seems to be how the necessary, large-scale or local, crustal extension required for granite emplacement can be obtained.

The Geologic Map of Georgia (1939) indicates that a small body of granite with a northerly elongation exists in the area. Preliminary investigations indicated that the body was composed of small granite pods oriented approximately perpendicular to the northeasterly regional structural trend. Field reconnaissance revealed the granite bodies to be inhomogeneous and to possess both gradational and apparent cross-cutting contacts with the surrounding rocks. The present investigation was undertaken with the hope of revealing the complex structural relations between the several types of granite and between the granite bodies and the country rock ... The geologic map was prepared with the major emphsis placed on the structural features and mineralogical differences between the rocks. Petrographic studies of the rocks included the examination of 237 thin sections and numerous polished sections.
The Appalachian orogen is separated from west to east and into the Cumberland Plateau, Valley and Ridge, Blue Ridge, Inner Piedmont, and Carolina Superterrane physiographic provinces. Within the southern Appalachians of Alabama and Georgia, the Inner Piedmont is composed of two Ordovician-aged volcanic arc and back-arc sequences that were later deformed, emplaced, and altered during the late Paleozoic Acadian and Alleghanian orogenies. These sequences appear within the Inner Piedmont as the Dadeville Complex (volcanic arc) and Opelika Group (back-arc). The Dadeville Complex is an allochthonous klippe which has been thrust atop its companion back-arc basin and is now fault-bounded to the southeast and northwest by the Stonewall Line and Katy Creek faults respectively. The local geologic structures within and between these two units, as well as characteristics of a large felsic intrusive complex within the Opelika Group, were studied in detail via field mapping, geochemistry, and petrography within and around the Mountville 7.5' quadrangle in Troup County, Georgia. The Stonewall Line, as observed in the Mountville quadrangle, does not support the theory proposed by other authors that involves the termination of the Stonewall Line into the Towaliga Fault south of the field area; it also does not follow the trend shown in the frequently cited map of Bentley and Neathery (1970). The observations made do support the idea that both the Dadeville Complex and Opelika Group continue northeast towards Atlanta, although the Stonewall Line appears to follow a path more easterly than previously thought The preliminary major and trace element geochemistry of a suite of granitic intrusions, referred to as the Odessadale Granite Gneiss, within the uppermost Opelika Group east of the mapping area support a correlation with similar granitic intrusions in the Inner Piedmont and eastern Blue Ridge; specifically the Farmville Metagranite and Lithonia Gneiss of the Inner Piedmont, and the Zana and Kowaliga Gneisses of the eastern Blue Ridge. Two granitoid bodies were also found that have intrusive relationships with the Odessadale, the redefined Gay Granite Gneiss, a low K2O/Na2O, peraluminous, seemingly I-type tonalite-trondhjemite, and one exposure of the herein named Big Springs Granodiorite, a low silica (63% SiO2), metaluminous, I-type tonalite-granodiorite with abundant biotite, hornblende, and minor pyroxene. Further geochemical investigation of the Odessadale Granite Gneiss, as well as the Gay Granite Gneiss and Big Springs Granodiorite, could reveal critical information related to the magmatic history and tectonic processes involved within the Wedowee-Emuckfaw-Dahlonega back-arc basin.
Bachelor Thesis from the year 2018 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 1, , language: English, abstract: Water is one of the most important natural resources that man is endowed with. Water is next to air as a major sustainer of life in addition to serving as a vital substance for human existence. It plays a major role in progress of our life and National development. In Nigeria majority of the water used domestically in villages, towns and cities are from the ground water resources. Water quality comprises of knowing the Geology and hydrogeology and environmental of the area of interest. In studying the Geology of an area one has to know the different rock types that bear the water in that area and the structures associated with it. Hydrogeology is area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the earth’s crust. It deals with flow of water through aquifers and other shallow porous media. The main aims and objectives of the study are as follows; 1. Determine the ground water quality in the boreholes and hand dug wells in the area and its suitability for domestic and agricultural uses. 2. To provide information for the use of organizations interested in ground water resource development in the area. 3. To satisfy one of the requirements for the award of degree of Bachelor of Technology (B.Tech) in applied Geology at the Abubakar Tafawa Balewa University.
