(University of Pretoria, 1992)Hierdie studie handel oar die struktuurgeologie en tektoniese geskiedenis van die noord-oostelike gedeel te van die Transvaalkom op die Kaapvaalkraton, Suid Afrika. Die strukturele grein van die studiegebied word deur ...
-
(University of Pretoria, 2020)Since the discovery of the Yeelirrie deposit in Australia in 1972, exploration for surficial uranium deposits has been supported through hydrogeochemical studies of groundwater and the calculation of the carnotite solubility ...
-
(University of Pretoria, 2020)An in-depth understanding of the physico-chemical nature of coal is required in order to meet ever-increasing energy demands and environmental legislature. New and classical coal analysis techniques were used on ...
-
(University of Pretoria, 2019)Partially saturated rock fracture flow informs on groundwater recharge processes, water affecting infrastructure, and water quality deterioration. This study examines partially saturated flow through natural fractures in ...
-
(University of Pretoria, 2019)Magnetite is a major constituent of the Upper Zone of the Bushveld Complex in South Africa. Magnetite occurs first as an intercumulus mineral, then as a cumulus mineral, then as massive monomineralic layers within the ...
-
(University of Pretoria, 2019)The tectonic framework of the Neoarchaean - Mesoproterozoic (2.58 to 1.87 Ga) supracrustal rocks exposed in the Thabazimbi region and Kumba Fe-Mine, Transvaal Supergroup, South Africa, has been studied using remote sensing ...
-
(University of Pretoria, 1980)Afrikaans: Damme word gebou om water in op te gaar en die invloed van water= druk op sulke strukture vereis dat die geologiese materiale waar= mee en waarop hulle gebou word bevredigend sal funksioneer. Ten einde die ...
-
(University of Pretoria, 2019)Implications of improved understanding of partially saturated flow in jointed rock masses are numerous, especially given the complexity, heterogeneity and anisotropy of the intermediate fractured vadose zone. One such ...
-
(University of Pretoria, 2018)Mining operations throughout the Bushveld Igneous Complex faces challenges in regards to the safe support of geological structures. Falls of Ground pose a massive risk to safety and production of any underground mining ...
-
(University of Pretoria, 2018)South African coals of the Main Karoo Basin, which are generally inertinite-rich, continue to be important to the country’s economic prospects. The formation of inertinite macerals present in coal continues to be a subject ...
-
(University of Pretoria, 2018)Most present cemeteries were sited without any consideration of the potential risks they may have to the local environment and community. The metals used in coffin-making may gradually weaken into harmful contaminants. ...
-
(University of Pretoria, 2019)Faults and dolerite dykes within Basement- and Karoo-aquifers in northern Mozambique may increase groundwater occurrence but may also be barriers to groundwater flow. Should observation boreholes drilled into regional and ...
-
(University of Pretoria, 2017)A research project was undertaken to delineate aquifers in Beaufort West. Recent studies in the Karoo Basin utilised geochemistry indicators to differentiate between shallow and deep groundwater. The shale gas exploration ...
-
(University of Pretoria, 2018)The high relief or mountainous basalt in and around the regions of Lesotho has extensive information on the nature and properties of the basalts, as a result of several developments on these basalts such as the Lesotho ...
-
(University of Pretoria, 2018)Water supply dams are essential infrastructural components, contributing to water security, ensuring economic growth. The construction of De Hoop Dam in South Africa is no exception. Water supply needs to keep abreast with ...
-
(University of Pretoria, 2017)The Cretaceous Zululand Basin is one of proposed areas for geological CO2 storage in South Africa. The knowledge of the basin is however very limited. This thesis aims to describe the sedimentary facies of the ZA core, ...
-
(University of Pretoria, 2018)Slope design and mining in foliated in-situ rock masses can be a major logistical and geotechnical hindrance. The Rock Mass Classification parameters need to be considered in relation to the anisotropic rock masses. What ...
-
(University of Pretoria, 2015)Adequate knowledge of the regional subsurface geometry depth relationship between the limbs and distribution of mineral zones within the Rustenburg Layered Suite (RLS) is required for better understanding of the emplacement ...
-
A three-dimensional model for the Leeuwpoort tin mine and its application to exploration prediction (University of Pretoria, 2017)Due to tighter financial margins, the need for better knowledge of grade data is required. Geological models allow the user to have a better understanding of the geological environment in which mining is taking place. Three ...
-
(University of Pretoria, 2017)With an estimated erupted volume of 300,000 km3 and an areal extent of more than 200,000 km2, the Paleoproterozoic (2.06 Ga) silicic volcanic rocks of the Rooiberg Group (Kaapvaal Craton) in northern South Africa forms ...
