Tectonic Framework and Low‐Oblique Rifting Kinematics of the Campos Basin, Southeastern Brazilian Margin

Tectonics, Volume 44, Issue 6, June 2025.
Abstract Understanding the tectonic framework of extensional margins is fundamental to unraveling kinematics, basement inheritance and magmatism during rifting. Using regional gravity and magnetic surveys, 2D and 3D seismic reflection data and well information in the Campos Basin, we conducted a systematic structural mapping of the syn‐rift building ...

Rhodolith Beds in Brazil—A Natural Heritage in Need of Conservation

Diversity and Distributions, Volume 31, Issue 1, January 2025.
ABSTRACT Aim Brazil harbours the largest known extent of rhodolith beds (RBs) in the world, a habitat whose ecological and economic importance have been widely overlooked. This creates a dire situation that is likely to worsen with the rapidly expanding human activities, considering that less than 5% of Brazil's ocean area is fully protected.
