About Dr Marvin Moroeng

​Biography

Dr. Marvin Moroeng holds a PhD in Geology (Coal Geology and Geochemistry) from the University of Pretoria (awarded in 2019), supervised by Dr. James Roberts and Prof. Nikki Wagner (UJ). He was first appointed as an Assistant Lecturer in the Department of Geology at the University of Johannesburg (UJ) in 2016 and was subsequently promoted to the position of Lecturer in 2018, following the completion of his doctoral studies. His current research areas, which he is undertaking in collaboration with Prof. Nikki Wagner and a number of postgraduate students at UJ, can be grouped into three main themes: (1) the origin of macerals in South African coals; (2) understanding the development and evolution of palaeomires using a combination of geochemistry (stable carbon isotopes) and petrology; and, (3) the effects of igneous intrusions on various coal properties. The research is undertaken mainly using a combination of petrological and geochemical techniques.

 

Beyond this, Dr. Moroeng is currently engaged in research into the coals of Inner Mongolia (China), in collaboration with the International Research Center for Coal Geology which is hosted by the China University of Mining and Technology (CUMT), Xuzhou. The collaborators on this project include Prof. Jian Shen, Prof. Shifeng Dai, Dr. Jingjing Liu (all based at CUMT) and Prof. Tim Moore (Cipher Coal Pty. Ltd., Australia). Dr. Moroeng is an Associate Member of the International Committee for Coal and Organic Petrology (ICCP) and a Member of the European Association of Organic Geochemists (EAOG). He has thus far published seven (7) papers in international journals, with five (5) as lead author.
