This sub-basin is part of the Moatize-Minjova Basin (MMB), a crucial Karoo aged coalfield in Mozambique previously situated in the southern-central part of Gondwana. The study of Lopes et al. (2021) presents the data of 3 coal exploration boreholes. This study enabled the characterization of the depositional environments and existing palaeofloras in the Muarádzi Sub-basin. The palynological data indicates that all the successions have a Lopingian age and the vegetation recorded is typical of the Glossopteris Province. The flora is dominated by glossopterids (Protohaploxypinus and Striatopodocarpites) and gymnosperm pollen (Alisporites). Other palynomorphs revealed the presence of ferns (e.g., Osmundidacites senectus, Thymospora pseudothiessenii), sphenopsids (e.g., Calamospora), and lycopsids (e.g., Lundbladispora, Kraeuselisporites) in the area. The palynological data, together with the palynofacies and lithofacies analysis, indicates a typical lowland setting. It was an area where floodplains, wetlands, and small lakes dominated, controlled by tectonic movements associated with a continental rifting pulse. Correlation between the three sections enabled the recognition of an initial meandering fluvial system affected by repeated flooding events that changed to a braided river. Additionally, humid and warm climates promoted widespread vegetation growth, leading to the accumulation of numerous thin barcode coal beds in anoxic-dysoxic depositional environments.
