Basin Research, Volume 37, Issue 3, May/June 2025.This work presents insights into the anatomy of the Paraná‐Etendeka volcanic sequences from subsurface geophysical data and how subsurface data aids in the stratigraphic correlation of volcanic formations regionally. Additionally, we describe facies distribution and reservoir properties, providing perspectives for CCS in the Paraná‐Etendeka LIP ...
