Book excerpt: 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.

Book excerpt: 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.

This book was released on 2013-04-24 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (postgraduate) from the year 2007 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: A, Abubakar Tafawa Balewa University, course: Applied Geology - Economic Geology/ Mineral Exploration, language: English, abstract: Barite (BaSO4) mineralization occurs within Pan African fracture systems in the Gombe inlier. Gombe Inlier is a Basement dome within the Gongola Basin (Upper Benue trough in Nigeria) which exposes most of the stratigraphic sequence (Bima Sandstone, Yolde Formation, Pindiga Formation and Gombe Sandstone). Fieldwork was conducted from March 23rd – 29th 2007, 20 minerals and rock samples were taken from the veins and host rocks, and then Geochemical, petrographic and structural analysis were conducted to ascertain the quality of barite, associated minerals, nature of host rock and also the type of chemical as well as structural barriers for the mineralization. The results shows that the principal planar planes hosting mineralizations were found to trend mostly in NE – WSW direction which conforms well in smaller scale with the trend of strike slip faults that faulted the inlier and on a larger scale conforms with the general trend of the Benue trough. The fractures are therefore probably subordinate to the general structural trend of the Benue trough. The main associated mineralization was inferred to be anhydrite (CaSO4) which is also a sulphate like barite. This suggest competition for SO32+ by Ba2+ and Ca2+ but the deeper fractures host barite because Ba2+ originate from mantle and brought up by hydrothermal fluid through fractures while Ca2+ could be a dissolved ion in sea water. The quality of the barite in some veins is well over 70% BaSO4 which is economically viable. Part of barite in some veins were leached and recrystallized into spindle crystals by later hydrothermal fluid with little effect on its chemistry. The petrographic studies also revealed the purity of some barite veins and also indicated the presence of other associated minerals and also indicates the nature of the silica chemical barrier for the sulphate mineralizations.

This book was released on 2018-08-13 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Project Report from the year 2017 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 5.0, , course: Geology, language: English, abstract: This study is aimed at determining the geology and depositional environment of Ameki Formation in Bende and environs through field descriptions, textural analysis and Palynological analysis. The mapped area which covers an area of about 180sq km and is located around Bende, southeastern Nigeria. The study area is bounded by Longitude 07° 30` E and 07° 43` E and Latitudes 05° 30` N and 05° 39` N. The area is underlain by Paleocene Imo Formation and Eocene Ameki Formation. The Ameki Formation is a clastic unit that overlies the marine Imo Formation and it consists of sandstone, shales, limestone, ironstone and siltstones. The Eocene Ameki Formation in southeastern Nigeria consists, in its type locality of five lithologic units; calcareous sandstone, pebbly bioturbated sandstone, grey-dark shale, argillaceous sandstone and pebbly sandstone. The floral, faunal and lithologic studies of the Eocene Ameki Formation suggest sediments deposited in a continuity from nearshore (barrier-ridge estuarine complex) to shallow marine (intertidal and subtidal zones) environment. The sieve analysis unveils that the univariate parameters indicate a fluvially intercepted shallow marine environment with tidal crosscuts, the log probability plots suggest tidal environment while from the bivariate plots; a beach influenced fluvial environment is interpreted. The pebble morphological analysis showed that the pebble clast have being shaped by beach action as revealed by the bivariate scatter plots of pebble form indices while in multivariate aspect a fluvially dissected shallow marine environment with tidal interferences was interpreted. The palynological analysis indicated a marginal marine source for the sediment and that the formation (Ameki) is Eocene in age.

Book excerpt: Research Paper (postgraduate) from the year 2019 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, Abubakar Tafawa Balewa University (APPLIED GEOLOGY), course: ECONOMIC GEOLOGY/MINERAL EXPLORATION, language: English, abstract: The study area received less attention from earlier workers which they consider the rocks as older granites that were barren, but according to this research work the rocks were found to be among the metamorphic terrain specifically migmatite rocks formed as part of northeastern Nigerian basement complex rocks which was affected by series of orogenic cycles that undergoes regional metamorphism and intrusion of younger granite rocks occurred sporadically in the study area. Detailed field mapping and sampling was done in order to identify and record the physical features of the rocks. Petrographic studies were conducted in both plane polarised light and cross polarised light in which microscopic structures were identified and noted. Field investigations and petrographic studies reveal that the rocks in the study area are metamorphic rocks based on certain structures observed, some of the structures include ptygmatic folding, crenulation cleavage, pinch and swell, andulus extinction and pleuchroic halo which are characteristics of metamorphic rocks. Therefore, the area was found to be underlaid by migmatite rocks which were classified as banded orthogneiss, straumalitic, and nebulitic migmatites and some intrusion of younger granites. Tin, tantalite, tourmaline and corundum mineralization were inferred.

This book was released on 2013-11-11 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2020-02-21 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the latest research on the structural geology of the mobile belts of the Indian subcontinent including the Himalayas, NE Himalayas, Bangladesh thrust belt, Andaman subduction zone, the Aravalli‐Delhi, the Central India Tectonic Zone, the Singhbhum, the Eastern Ghats and the Southern granulite terrane. It offers essential information on deformational structures in the mobile belt, such as folding patterns, the character of the shear zone, shear strain analysis, and faults, as well as fault zone rocks. The findings presented here are based on field observations, mapping, sampling and analysis work (e.g. petrographic studies), as well as limited geochemical and geochronological analysis to support the findings. A discussion on the structural evolution of these mobile belts and their connections with other belts rounds out the coverage.
