(University of Pretoria, 2016)Experimental research was undertaken to exploit the use of an innovative laser scanning tool and to apply the equipment to the study of (G1) road construction aggregate obtained from crushed rock quarry sources. The aim ...
-
(University of Pretoria, 2015)The Gamsberg East orebody is the least studied orebody of the Gamsberg zinc (Zn) deposit. The Gamsberg Zn deposit is a largest undeveloped Broken Hill-type deposit, which is well known for relatively low zinc grade as ...
-
(Elsevier, 2016-04)Mine tailings can represent untapped secondary resources of non-ferrous, ferrous, precious, rare and trace metals. Continuous research is conducted to identify opportunities for the utilisation of these materials. This ...
-
(South African Institution of Civil Engineering, 2016-03)The Karoo Supergroup covers approximately 57% of South Africa’s surface area and the sedimentary rocks therein generally do not yield acceptable pavement aggregates. The Karoo Dolerite Suite (intrusions) present in these ...
-
(Elsevier, 2016-05)A sound understanding of the various factors influencing and associated with the formation of sinkholes or subsidences on dolomite land is essential for the selection of appropriate rehabilitation methods. The investigation ...
-
(University of Pretoria, 1976)Nunataks within an area of approximately 3 400 km2 between latitudes 71°50' and 72°35' south and longitudes 1°30' and 4°00' west were mapped geologically by the 12th South African National Antarctic Expedition during ...
-
(International Union of Geological Sciences, 2015-09)The Mio-Pliocene Middle Siwalik Subgroup, in the Lish River Section in the Darjiling District of the Eastern Himalaya, consists of sandstone, mudrocks, heterolithic units and conglomerates preserving six distinct associations ...
-
(Springer, 2016-02)A petrography–geochemistry-based evaluation of the provenance of the sandstones of the Tertiary Middle Siwalik Subgroup in the Lish River Valley, West Bengal, is presented. The framework grains in the sandstones ...
-
(Sociedad Geológica Mexicana, 2015)La estratigrafía del pozo profundo San Lorenzo Tezonco registra una intensa actividad volcánica en la Cuenca de México y alrededores durante los últimos 20.1 Ma. La columna litológica de 2008 metros de profundidad está ...
-
(CONSAS Conference, 2015-08)A preliminary investigation was done into the possible causes of the increased seismic activity in the Witwatersrand Basin. The paper focuses on approximated underground mining areas, groundwater mobility, rock types and ...
-
Hymnal record of a missionary structure at Thabantsho (Gerlachshoop) of the Bakoba of Kgoshi Boleu (Church History Society of Southern Africa, 2015)This research sets out to answer a problem involving whether or not the first church was established across the Vaal River in the 1860s at Gerlachshoop (Maleoskop). An incidental find of an unknown publication may ...
-
(Elsevier, 2016-03)The present paper highlights the sequence development within the Mesoproterozoic Koldaha Shale Member of the Kheinjua Formation, Vindhyan Supergroup which records the occurrence of a forced regressive wedge and associated ...
-
(Elsevier, 2016-06)The morphology and mineral chemistry of gold and associated sulphides at Sheba, Fairview, and New Consort gold mines in the Barberton Greenstone Belt (BGB) identify two main types of mineralization. The first type ...
-
(Actuarial Society of South Africa, 2015)A methodology for the assessment of the probable maximum loss associated with an earthquake is described and applied to the Cape Town central business district. The calculations are based on the effect of the two largest ...
-
(Springer, 2015-04)The Ituwa Surge deposits belong to the Holocene Ngozi volcano (volcano number 222164 of the Smithsonian Institute Global Volcanism Program; Siebert et al. 2010) of the Rungwe Volcanic Province (RVP; Harkin 1960; Lenhardt ...
-
(University of Pretoria, 2016)Gem garnet chemistry is described using the end-members pyrope, almandine, spessartine, andradite, grossular, and uvarovite. The large variation in garnets makes classification difficult. Garnet gemstones are typically ...
-
(South African Institution of Civil Engineering, 2015-06)A large part of the land south of Pretoria is underlain by dolomite from the Chuniespoort Group of the Transvaal Supergroup. In South Africa, dolomite rock has a notorious reputation for the formation of sinkholes and ...
-
(University of Pretoria, 2015)Mining operations associated with the primary production of PGE’s in South Africa have generated and continue generating large quantities of mineral waste and by-products, for instance in the form of tailings. Mine tailings ...
-
(Elsevier, 2015-07)The present study deals with the Neoproterozoic mat-infested substrate sculptured by inferred bioturbations, excellently preserved within the ca. 600 Ma Sonia Sandstone, northwest India. The bioturbations are horizontal, ...
-
(Taylor and Francis, 2016)Eleven new baddeleyite U–Pb crystallisation ages and associated whole-rock geochemistry on NE–NNE-trending tholeiitic dykes cutting across the north-eastern corner of the Archaean Kaapvaal Craton, the overlying Transvaal ...
