Professor Marlina A. Elburg

Department of Geology, University of Johannesburg, 011-5594708

Research keywords: igneous petrology, radiogenic isotopes, geochronology

Marlina Elburg’s vital statistics are that she is an NRF B-rated scientist, with more than 120 peer-reviewed papers in international journals to her name. She has successfully (co)supervised ten MSc and six PhD students, is the scientific editor of the South African Journal of Geology and associate editor for Journal of Petrology.

Marlina’s research is focussed on igneous petrology and geochemistry, and the application of geochemical analytical techniques to other fields of science, such as archaeology and conservation sciences. Together with colleagues and students, she has has worked on granites of the Australian Palaeozoic fold belts, mafic dykes of the Karoo province and island arc volcanics of the Indonesian and Aegean Arcs. Since arriving in South Africa in 2011, she has looked at the South African – Antarctic connection in the Rodinia and Gondwana supercontinents, focussing on the Natal Belt and eastern Dronning Maud Land (Sør Rondane).

The Pilanesberg Alkaline Province and Namaqua pegmatite belts are other ongoing projects. Zircon studies have become a prominent part of her research, with the U-Pb and Lu-Hf isotopic systems as indicators for igneous process as well as sedimentary (re)cycling. The NRF-funded laser ablation multi-collector ICPMS equipment, which has been operational since February 2016, is an important tool for these projects. In collaboration with colleagues from Wits, who are in charge of the clean lab there (WIGL), the necessary techniques for the whole rock analysis of Rb-Sr, Sm-Nd and Lu-Hf systems have been developed.
