Tectonic Framework of the Arenópolis and Anicuns‐Itaberaí Segments of the Goiás Magmatic Arc Based on 3D Magnetotelluric Inversion

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The Goiás Magmatic Arc (GMA) is a Neoproterozoic juvenile terrain formed through oceanic‐oceanic and oceanic‐continental subduction. It comprises three main segments: Mara Rosa, Anicuns‐Itaberaí (GMAAI), and Arenópolis (GMAA), whose tectonic evolution and connectivity remain uncertain.
