    A Glimpse into Mafic Magma Genesis in South Africa: Over the First 1.5 Billion Years of Earth History
    (University of the Witwatersrand, Johannesburg, 2011-11) Wilson, Allan
    This talk will cover three areas of geology that I believe are important in the igneous history of South Africa spanning the first 1.5 billion years from 3.5 Ga to 2.0 Ga. The high-Mg lavas in Barberton and KwaZulu-Natal called komatiites 3.5 – 3.3 billion years ago. The volcanic rocks of the Pongola Supergroup 3.0 – 2.9 billion years ago. The Bushveld Complex 2.05 billion years ago.
