Geological Relationships Among the Barberton Greenstone Belt, Black Reef Quartzites, Limpopo Banded Iron Formation, and Malmani Subgroup Buchanan 2024 Abstract This paper explores the geological relationships among the Barberton Greenstone Belt, Black Reef Quartzites, Limpopo Banded Iron Formation (BIF), and Malmani Subgroup in South Africa. It provides a timeline of their formation, highlighting the transitions in depositional environments and the significance of these formations in understanding early Earth processes. 1. Introduction The geological history of South Africa is marked by significant formations that provide insights into the early Earth. This paper examines the relationships among the Barberton Greenstone Belt, Black Reef Quartzites, Limpopo BIF, and Malmani Subgroup, focusing on their ages and depositional contexts. 2. Geological Context and Timeline 2.1 Barberton Greenstone Belt The Barberton Greenstone Belt is one of the oldest geological formati...
