Jolayemi, Olutula Olumayowa(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 ...
Extensive research has been done on the investigation, evaluation, development and
management of land underlain by dolomite to prevent the formation of sinkholes and subsidences.
Little emphasis is, however, given to the ...
The drill core of borehole NZA, drilled in the southwest margin of the onshore
Zululand Basin to a depth of ca. 571 m was investigated in this study. In this thesis
descriptions of the geochemistry, mineralogy and physical ...
Letsoele, Christopher Sbusiso(University of Pretoria, 2017)
This study presents a detailed petrological and geochemical investigation of the concordant ultramafic
pegmatites of the Lower Critical Zone at Dwarsrivier Mine, in the eastern Bushveld Complex. The
pegmatites are ...
Very limited studies have been conducted on titaniferous-magnetite exsolution textures and
the conditions needed for the formation of these textures. Published research surrounding
the exsolution textures consider only ...
The Tshipise Basin is considered to be a fault bounded remnant of a larger Karoo aged basin
that was fragmented and preserved in the outline seen today by a number of ENE-WSW and
NW-SE trending basement faults. It consists ...
Oyelami, Charles Adebayo(University of Pretoria, 2017)
Lateritic soils which have been described as highly weathered tropical or sub-tropical residual
soils with varying proportions of particle sizes ranging from clay size to gravel, were studied
in an attempt to establish ...
Brouwers, Luke Bernhard(University of Pretoria, 2017)
The underlying mechanisms governing unsaturated flow from soil into fractured rock in
the intermediate fractured vadose zone is still poorly understood despite occurring in
numerous areas of application. To gain a better ...
Mine water chemistry and its evolution has been the focus of various studies. However, these
studies were primarily based on data from underground mines, pit lakes and mining waste dumps.
Backfilled opencast mines have ...
Ibinoof, Montasir Ahmed(University of Pretoria, 2017)
Dismembered and low-grade metamorphosed occurrences of mafic extrusive and
intrusive and minor ultramafic rocks, grouped as the Arid unit, similar to those of the
Arabian Nubian Shield (ANS), are reported here for the ...
The majority of seismic activity in South Africa is related to extensive mining operations, usually in close proximity to densely populated areas where a relatively weak seismic event could cause damage. Despite a significant ...
Merkle, R.K.W. (Roland Karl Willi), 1954-; Malitch, Kreshimir Nenadovitch; Graser, Peter P. H.; Badanina, Inna Yu.(Japan Association of Mineralogical Sciences , 2012-01)
Native osmium from two different placer occurrences
(i.e., Ingaringda and Burlakovsky) within the Guli
Massif, Maimecha-Kotui Province, was evaluated for mineral
compositions that show systematic differences between ...
The problem considered in this study is that of unrealistic ground motion estimates, which arise in the Cornell–McGuire method when the seismic hazard curve is calculated for extremely low annual probabilities of exceedance. ...
Bamisaiye, O.A.; Eriksson, Patrick George; Van Rooy, J.L. (Jan Louis); Brynard, H.M.; Foya, S.; Billay, A.Y.; Nxumalo, V.(Elsevier, 2017-08)
Faults and other structural features within the mafic-ultramafic layers of the Bushveld Complex have been a major issue mainly for exploration and mine planning. This study employed a new approach in detecting faults with ...
Saunders, I.; Kijko, Andrzej; Fourie, C.J.S.(Geological Society of South Africa, 2016)
We analyzed the changes/improvements of seismic event detection and location accuracy of the South African
National Seismograph Network over the last four decades. The effect of three regional velocity models on
Richards, Ralph John(University of Pretoria, 1987)
The stratigraphy , sedimentology and geochemistry of. the upper Transvaal
Sequence rocks in the northern portion of the Rooiberg Fragment are
The Leeuwpoort Formation of the Pretoria Group was deposited in ...
During the refining of steel by basic processes, a multitude of mineralogical
reactions take place in the refractories with which the furnace
is lined. The reactions are caused by an influx of material from
the slag and ...
Jansen van Vuuren, Melchior Changuion(University of Pretoria, 1989)
From available records and data of colliery product samples, an area
within the Witbank and Highveld coalfields was selected for this study.
The petrographic and elemental nature of the coal seams have been
derived from ...
Low-grade tin deposits occur within the apex of the Bobbejaankop
Granite intrusion at the Zaaiplaats Tin Mine. The finegrained
hood-facies of the Bobbejaankop Granite, called the
Lease Granite, seems to be intrusive ...
Strydom, Johan Hendrik(University of Pretoria, 1983)
A mineralogical and geochemical investigation of the country rock
around pipe-like ore bodies in the Lease Granite was undertaken to
obtain a better understanding of the conditions of formation of the
pipes. It was also ...
