| dc.description.abstract | This is a report about a Field Mapping Exercise of Igayaza area, Isingiro District carried out from 31st/05/2023 to 7th/06/2023 and different activities such as collecting samples, taking field notes, measurements, GPS readings, sketching structures and landforms were done in groups and also presentations in areas mapped (hot spots) and excursion were carried out under the department of geology and petroleum studies Makerere University in South Western Uganda. The main aim of the mapping project was to enable students practically learn field geological mapping skills and apply these skills in future prospective exploration. During the mapping project, a lot was learnt including field observations, collecting raw data. Laboratory data analysis and interpretation, statistical data processing and interpretation, written and oral geological reporting. The report is comprised of a detailed geological study of area B-Kaharo which was my main area of study. The mapped area B is situated on the NW limb of the Gayaza synclinorium and is part of the Karagwe Ankolean system which belongs to the Meso-Neo Proterozoic cover formations. The information about the mapping exercise is discussed in six main chapters which are; introduction, stratigraphy, structures, petrography and metamorphism, regional synthesis and conclusion. The introduction defines the objectives of the field trip, location of mapped area, methods and materials used. Stratigraphically, rocks were deposited in the order of shales, sandstones that later metamorphosed to quartzites that occupy the top of ridges which were later intruded by granites. Quartzites overlie shales which overlie slates. Slates are underlined by phyllites and finally granites at the base. The major structures in the area were: beddings, faults, folds and joints all exhibiting two major trends; NW-SE trend which is similar to that of the regional folds and NE-SW direction. Metamorphism of these rocks was low grade regional metamorphism evidenced by foliation and some index minerals such as chlorite. The grade of metamorphism increased towards the arena. In conclusion, the mapped area B is located in the lower Karagwe- Ankolean and it has generally a hilly topography with intervening lowlands (arenas) and one of the characteristic hills of Kaharo were the Breast hills. | en_US |
