Multispectral remote sensing of potential groundwater dependent vegetation in the greater Floristic region of the Western Cape, South Africa
(Taylor and Francis Group, 2023)Groundwater dependent vegetation (GDV) is increasingly threa-tened by the transformation of the natural environment. An under-standing of the nature of GDV at the appropriate scale helps environmental managers make suitable ... -
Periodic low-frequency electric field structures in a magnetized non-thermal auroral plasma
(Elsevier, 2019)The theoretical explanation of electric field structures associated with density depletion in the Earth’s upper ionosphere is presented. Using the quasi-neutrality hypothesis, the effect of excess energetic electron ... -
Sandstone reservoir zonation of the north-western Bredasdorp Basin South Africa using core data
(Elsevier, 2021)This study delineates sandstone reservoir flow zones in the north-western Bredasdorp Basin, offshore South Africa, using conventional core porosity and permeability data. The workflow begins by integrating sedimen- tology ... -
The timing and tectonic context of Pan-African gem bearing pegmatites in Malawi: Evidence from Rb–Sr and U–Pb geochronology
(Elsevier, 2023)The Pan-African belts of Malawi contain a largely unexplored endowment of gem bearing pegmatites. We present U–Pb in zircon (LA-ICPMS) and Rb–Sr mineral isochron geochronological and isotope data from pegmatites across ...
