New Kinematic Model of the Early Opening of the Equatorial Atlantic Realm
Tectonics, Volume 44, Issue 5, May 2025.Abstract The opening of the Equatorial Atlantic Ocean constitutes the final stage of Gondwana's breakup, leading to the separation of the African and South American continents. The early spreading has been debated due to the absence of magnetic anomalies related to the Early Cretaceous opening at low latitude, and an incomplete fracture zone record ...

Interglacial dust, ocean fertilisation and Neoproterozoic earth oxygenation
The Depositional Record, Volume 11, Issue 2, Page 654-674, April 2025.Mineral dust is an integral part of modern ocean nutrient supply. It is originated mainly in deserts and by glacial processes. Given the global scale of the Neoproterozoic glaciations, we suggest that mineral dust formed during snowball events were blown to oceans, sustaining life, promoting CO2 sequestration and contributing to the oxygenation of ...

The lithospheric structure of Pangea [PDF]
Lithospheric thickness of continents, obtained from Rayleigh wave tomography, is used to make maps of the lithospheric thickness of Pangea by reconstructing the continental arrangement in the Permian. This approach assumes that lithosphere moves with the
