About Dr Senamile Siyaya Dumisa

Dr. Senamile Dumisa is a dedicated geoscientist with a passion for unlocking the mysteries of Earth’s geological formations. Beginning her academic journey at Wits University, Dr. Dumisa’s thirst for knowledge led her to pursue a PhD, which she successfully completed in 2024. Her doctoral research delved into the intricate realm of orbicular granites and sulphide mineralisation in the Koperberg Suite, South Africa, and the Diana’s Pool area, Zimbabwe. Through her study titled “Constraints on the genesis of the orbicular granites and sulphide mineralisation”, Dr. Dumisa sought to unravel the complexities surrounding these rare geological formations, shedding light on their petrogenesis.

As a Postdoctoral Fellow, Dr. Dumisa has joined the University of Johannesburg and the esteemed Kunene team, where she is committed to advancing the understanding of how the Kunene Anorthosite Complex crystallised. Her primary research interests span petrology, geochemistry, and economic geology, reflecting her multidisciplinary approach to geological exploration and analysis.

Project title:

A machine learning approach to constrain P-T of crystallisation of the Kunenene Anorthosite Complex and its mafic-ultramafic intrusions.
