A metamorphic origin for Europa's ocean
(John Wiley & Sons, Inc, 2021)Europa likely contains an iron-rich metal core. For it to have formed, temperatures within Europa reached urn:x-wiley:00948276:media:grl62926:grl62926-math-00011250 K. Going up to that temperature, accreted chondritic ... -
Timing of Proterozoic magmatism in the Sunsas belt, Bolivian Precambrian Shield, SW Amazonian Craton
(Elsevier B.V., 2021-06-05)We present new U–Pb zircon and monazite ages from the Sunsas belt granitic magmatism in Bolivia, SW Amazonian Craton. The geochronological results revealed four major magmatic events recorded along the Sunsas belt domains. ... -
Assessment of C, N, and Si Isotopes as tracers of past ocean nutrient and carbon cycling
(John Wiley & Sons, Inc., 2021)Biological productivity in the ocean directly influences the partitioning of carbon between the atmosphere and ocean interior. Through this carbon cycle feedback, changing ocean productivity has long been hypothesized ... -
Oceanographic anomalies coinciding with humpback whale super-group occurrences in the Southern Benguela
(Nature, 2021-10-22)Seasonal feeding behaviour of humpback whales (Megaptera novaeangliae) has been observed in the coastal waters of the Southern Benguela where the species has been observed forming super-groups during the austral spring in ... -
Magmatic and metamorphic evolution of the Stolzburg Block, Barberton Granitoid-Greenstone Terrain
(Stellenbosch : Stellenbosch University, 2022-12)ENGLISH ABSTRACT: The processes that formed and shaped the first stable continents in the Archean are poorly constrained for various reasons, including the scarcity of well-preserved, unaltered rock sequences and the ... -
Fluorescence detection of trace aluminium using a sequential injection analyser
(Stellenbosch : Stellenbosch University, 2022-12)ENGLISH ABSTRACT: Analytical instruments are either expensive to operate, prone to interferences, require a separate offline preconcentration step, or are not suitable for use onboard a ship when measuring dissolved ... -
Diminutive fleet-footed tyrannosauroid narrows the 70-million-year gap in the North American fossil record
(Springer Nature, 2019-02-21)To date, eco-evolutionary dynamics in the ascent of tyrannosauroids to top predator roles have been obscured by a 70-million-year gap in the North American (NA) record. Here we report discovery of the oldest Cretaceous NA ... -
Dissolved iron in the North Atlantic Ocean and Labrador Sea along the GEOVIDE section (GEOTRACES section GA01)
(2020-02-21)Dissolved Fe (DFe) samples from the GEOVIDE voyage (GEOTRACES GA01, May–June 2014) in the North Atlantic Ocean were analysed using a SeaFAST-picoTM coupled to an Element XR HR-ICP-MS and provided interesting insights on ... -
Recharge estimation using CMB and environmental isotopes in the Verlorenvlei Estuarine System, South Africa and implications for groundwater sustainability in a semi-arid agricultural region
(MDPI, 2020-05-12)Groundwater recharge remains one of the most di cult hydrogeological variables to measure accurately, especially for semi-arid environments where the recharge flux is much smaller than in humid conditions. In this study, ... -
Mantle and crust interaction in post-collisional setting, a case study of lamprophyric-granitic composite dykes of northern Aigoual pluton, French Massif Central
(Stellenbosch : Stellenbosch University, 2022-04)ENGLISH ABSTRACT: Lamprophyre to granite composite dykes in the northern extremity of the post-Variscan Aigoual pluton, French Massif Central (FMC), offer an opportunity to study the complexity of the processes that ... -
Understanding Southern Ocean phytoplankton ecophysiological response to iron availability
(Stellenbosch : Stellenbosch University, 2022-04)ENGLISH ABSTRACT: Over the past century, climate change has been of growing concern, due to its ecological and economic global impact. The Southern Ocean buffers the impacts of climate change by accounting for a significant ... -
Application of 87Sr/86Sr ratios to discerning groundwaters from different lithostratigraphic units in the Southwest coastal region of South Africa
(Stellenbosch : Stellenbosch University, 2022-04)ENGLISH ABSTRACT: South Africa has been significantly affected by climate change and has experienced reoccurring drought conditions induced by low precipitation levels and resulting in declining surface freshwater levels. ... -
An investigation of magma mingling and potential magma mixing during the intrusion of mafic melts into metasediments undergoing partial melting in the Dalradian series of eastern Scotland
(Stellenbosch : Stellenbosch University, 2022-04)ENGLISH ABSTRACT: In order to understand the evolution and differentiation of the Earth, the petrogenesis of chemically evolved intermediate to felsic rocks which are characteristic of Earth’s continental crust, is of ... -
Microfossil characterisation for petroleum exploration using x-ray computed tomography: a new approach
(Stellenbosch : Stellenbosch University, 2022-04)ENGLISH ABSTRACT: The current bulk processing and identification of microfossils from drill cores for petroleum exploration are limited by time-consuming traditional chemical and physical microfossil extraction and ... -
Insights into early winter Southern Indian Ocean dissolved iron distributions and remineralisation using excess barium (GEOTRACES GIPr07 cruise)
(Stellenbosch : Stellenbosch University, 2022-04)ENGLISH ABSTRACT: The Southern Ocean is of central importance to the global ocean, connecting the Atlantic, Pacific and Indian basins via the Antarctic Circumpolar Current, which carries large amounts of heat, carbon and ... -
Archaeal membrane lipid-based paleothermometry for applications in polar oceans
(The Oceanography Society, 2020-06)To establish whether ongoing climate change is outside the range of natural variability and a result of anthropogenic inputs, it is essential to reconstruct past oceanic and atmospheric temperatures for comparison with the ... -
Die bergplase van Piketberg
(Stellenbosch : Stellenbosch University, 1957-12)AFRIKAANSE OPSOMMING: Voordat die geskiedenis van die berg nagegaan kan word, is dit nodig om 'n breër agtergrond te verkry, en veral te wys op die wyse waaarop Piketberg, sy naam gekry het. Die eerste bewoners van die ... -
Characterizing the fungurume 88 deposit in the tenke fungurume mining district: an unusual, high-grade, primary cobalt sulphide deposit
(Stellenbosch : Stellenbosch University, 2021-12)ENGLISH ABSTRACT: The Tenke Fungurume Mining (TFM) district, situated in the northern parts of the Central African Copperbelt (CACB), exhibits one of the most renowned clusters of sedimentary stratiform ... -
Southern African dust characteristics and potential impacts on the surrounding oceans
(Stellenbosch : Stellenbosch University, 2021-12)ENGLISH ABSTRACT: This study supports understanding the potential impact of dust aerosols from southern Africa have on the proximal ocean ecosystems. Dust can release essential nutrients and thus fertilize the ocean, ... -
