The Interaction of the Eastward Extrusion of the Songpan‐Ganzi Terrane and the Crustal Rotational Movement of the Sichuan Basin Since the Late Paleogene: Evidence From Cretaceous and Paleogene Paleomagnetic Data Sets of the Sichuan Basin

Since ~40 Ma the eastward extrusion of the Songpan‐Ganzi Terrane (SGT), induced by the continuous convergence of the Indian Plate and Eurasia, was resisted by the Sichuan Basin which led to complex crustal rotational deformation of the basin edge. The interaction between the eastward extrusion of the SGT and crustal rotational movement of the Sichuan Basin is the key to understand the Cenozoic crustal deformation of the eastern edge of the...
