Rifting Evolution of the Central Campos Basin as a Hybrid Rifted Margin: Insights From Tectonic and Magmatic Structures

Tectonics, Volume 45, Issue 1, January 2026.
Abstract Recent observations and drilling campaigns have challenged the typical models for rifted margins by providing evidence for the existence of intermediate cases between the magmatic and amagmatic end‐members. In this contribution, we document the evolution of the Central Campos rifted margin, located in southeast Brazil, based on a combined ...
