(Geological Society of South Africa, 2020-12)Multispectral sensors, along with common and advanced algorithms, have become efficient tools for routine lithological discrimination and mineral potential mapping. It is with this paradigm in mind that this paper sought ...
-
(Geological Society of South Africa, 2020-12)The Palaeoproterozoic Hekpoort Formation of the Pretoria Group is a lava-dominated unit that has a basin-wide extent throughout the Transvaal sub-basin of South Africa. Additional correlative units may be present in the ...
-
(Elsevier, 2020-11)With an increasing population, development of the country and a changing climate, demand for fresh water has increased and is coupled with negatively impacted water resources. One impacted component of the water resource ...
-
(Elsevier, 2020-12)Water quality globally suffers from overuse and pollution, but desert areas with high evaporation rates and groundwater as the only water source have additional challenges. Namakwaland in the Northern Cape is an arid region ...
-
(Cambridge University Press, 2020-09)Please read abstract in the article.
-
(MDPI, 2020-11-25)The Vredefort impact structure in South Africa is deeply eroded to its lowermost levels. However, granophyre (impact melt) dykes in such structures preserve clasts of supracrustal rocks, transported down from the uppermost ...
-
(Wiley, 2021-01)Understanding the character of hail is an important part of mitigating its impact on life and property. Climatologies of hail over South Africa are rare and based on observed data with a coarse spatial and temporal resolution. ...
-
(Springer, 2021-01)The so-called mud cracks, possibly the most common deformation feature in sediment, are evident in almost all dried-up exposed sediment surfaces. Several experimental attempts have so far been made to explain the evolution ...
-
(Geological Society of South Africa, 2019-09)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 ...
-
(Wiley, 2021-03)Please read abstract in the article.
-
(Academy of Science South Africa, 2019)Isotopes are atoms that belong to the same element, but have different numbers of neutrons. For example, hydrogen can have 0 neutrons (protium) or 1 neutron (deuterium) or 2 neutrons (tritium). The mass changes because ...
-
(Springer, 2019-04)The Secondary Permeability Index (SPI) is a permeability-based rock mass classification, which when complemented with the degree of jointing can be employed as an approximation to the ground treatment design. However, when ...
-
(BioMed Central, 2020-08)BACKGROUND: In this multidisciplinary study we present soil chemical, phytochemical and GIS spatial patterning evidence that fairy circles studied in three separate locations of Namibia may be caused by Euphorbia ...
-
(Elsevier, 2020-10)Impact-generated pseudotachylites (PTs) have been extensively studied in the Vredefort Impact Structure, South Africa, and have been shown to correspond chemically and isotopically to their host rocks. Such melts are ...
-
(Geological Society of South Africa, 2019-09)South African geology, geomorphology and climate are distinctly variable, resulting in a complex hydrological cycle superimposed on equally complex ground conditions. With fractured and karstic systems dominating ...
-
Stable isotope constraints on hydrostratigraphy and aquifer connectivity in the Table Mountain Group (Geological Society of South Africa, 2019-09)The Table Mountain Group is a folded, faulted, quartzite-dominated sedimentary sequence, metamorphosed to lower greenschist facies, that forms steep mountains dominating the topography of the Western Cape and causing ...
-
(Geological Society of South Africa, 2019-09)The properties of residual dolomite, sometimes termed wad, are variable and uncertain. It represents the insoluble residue after dissolution of dolomite and is commonly found in the Neoarchaean Malmani Subgroup of ...
-
(Geological Society of South Africa, 2019-09)Gypseous soils occur in the western arid and semi-arid regions of South Africa and Namibia. These soils exhibit a complex nature and abnormal behaviour due to their gypsum content and as such they have become more ...
-
(Taylor and Francis, 2019)The initial standard narrative of how New Zealand was thought to be settled by a relatively small number of Polynesian people over centuries of gradual adaption grew from the estimates of genealogical reckoning or whakapapa ...
