Exhumed Serpentinites and Their Tectonic Significance in Non‐Collisional Orogens
Geochemistry, Geophysics, Geosystems, Volume 25, Issue 2, February 2024.Abstract Exhumed serpentinites are fragments of ancient oceanic lithosphere or mantle wedge that record deep fluid‐rock interactions and metasomatic processes. While common in suture zones after closure of ocean basins, in non‐collisional orogens their origin and tectonic significance are not fully understood.
