Paleoenvironmental and vegetation evolution during the PETM in the Gulf of Guinea: A study based on integrated palynological and chemostratigraphic analysis of the Miang section in the Douala Basin, Cameroon
The Paleocene–Eocene environment and vegetation evolution is widely documented worldwide. While a few similar studies have been undertaken in the Gulf of Guinea and the continental interior, they remain very limited, and provide no evidence of the Paleocene–Eocene thermal maximum (PETM). To address…

The supergiant Witwatersrand Goldfield: A result of anhydrous mantle degassing on Earth’s earliest supercontinent
The origin of the supergiant high grade Witwatersrand gold deposits has attracted debate for several decades with modified gold placer models contrasting with orogenic gold crustal metamorphic models. Neither explains the anomalous quantities of gold, pyrobitumen, and ‘carbon leaders’ in the Basin…
