| dc.description.abstract | This report comprises a detailed compilation of findings, analysis, interpretations, conclusions and recommendations for the Igayaza-Isingiro geological mapping exercise and field excursion to south western Uganda. The Geological mapping exercise was carried out in Igayaza, Isingiro district, western Uganda which lies within the Karagwe-Ankolean system of rocks (ca. 1400-950 Ma), which is the northern most extension of the Kibaran mobile belt with the aim of acquainting students with skills in geological mapping. This project aiming at practically enhancing students’ skills in geologic mapping projects. Materials used included; a geologic hammer, handheld GPS, tape measure, notebook and a compass and the rock samples collected, sorted and taken to the laboratory for further analysis. The data acquired for structures compiled with laboratory data was interpreted and analyzed. The findings were compiled with its interpretation made. This report looks at the stratigraphic correlation of the mapped area C with that of the entire Karagwe-Ankolean system which suggests that the mapped area has a stratigraphic column similar to that of South-West Uganda. This correlation is aided by the use of the geologic map of area C and its corresponding cross-section and stratigraphic column. The information about the mapping exercise is discussed in six main chapters which are; introduction, stratigraphy, regional synthesis, structures, petrography and metamorphism and conclusion. The introduction defines the objectives of the field trip, location of mapped area, methods and materials used.The lithology comprised of thin arenaceous formations that were predominated by quartzites while the thick argillaceous formations constituted shales. The quartzites were mainly found at the ridge summits while the shales were found along the flanks of ridges and in valleys between ridges. The grades of metarmorphism was varying from low grade regional metamorphism which was evidenced by presence of beddings and some index minerals such as chlorite, muscovite. Sandstones and shales were metamorphosed to quartzites and phyllites respectively. Contact metamorphism occurred around granitic intrusions that formed most of the arenas (broad stadium like structures).The structures in the mapped area include joints, beddings, faults, quartz veins, folds; these were mapped at different scales. The economic potential of the area is low since no economic minerals have been discovered. However, some of the economic activities carried out include; farming, cattle keeping, forestry, quarrying and brick making.At the end of the mapping exercise, hotspot presentation were done where students would take lecturers and students to the most interesting areas in their region mapped. | en_US |
