Dr. Xolane Mhlanga

Postdoctoral research project: Controls on iron distribution in manganese deposits of the Postmasburg Manganese Field

Supervisor: Prof Hari Tsikos

Sponsor: DST-NRF-CIMERA

Biographical

Xolane (or “X”, as widely referred to by his friends) comes from the town of Kanyamazane in the scenically beautiful province of Mpumalanga in South Africa. He completed a BSc degree in 2012 at Rhodes University, with majors in Geology and Environmental Science. In 2013, he obtained his Honours degree in Geology, as part of which he carried out a project on small-scale ore-grade relationships in Hotazel manganese ore at Gloria mine in the Kalahari Manganese field. His PhD project was essentially a continuation of his earlier work, with emphasis on understanding the interplay between primary and diagenetic cycling of carbon in the Hotazel formation, through the combined use of mineral chemistry, stable isotope geochemistry and iron speciation techniques. His main extramural interest is sports, especially soccer.

PhD project title (completed)

A reappraisal of the origin of the Hotazel Fe-Mn Formation in an evolving early Earth system through the application of mineral-specific geochemistry, speciation techniques and stable isotope systematics
