Rift and supradetachment basins during extension: insight from the Tyrrhenian rift Alfonsa Milia Maurizio M. Torrente 10.6084/m9.figshare.3453857.v1 https://geolsoc.figshare.com/articles/journal_contribution/Rift_and_supradetachment_basins_during_extension_insight_from_the_Tyrrhenian_rift/3453857 <p>The style of extensional basins provides key insights into the magnitude of extension and their kinematic evolution. The newly documented Stilo rift (off Calabria, Italy) features a Serravallian–Tortonian rift basin bounded by a high-angle normal fault and a Messinian adjacent supradetachment basin bounded by a low-angle normal fault. We propose a kinematic model suggesting the abandonment of the high-angle normal fault and the beginning of low-angle normal fault activity, followed by a rapid increase in extension. The triggering mechanism of the low-angle normal faults can be attributed to rapid rollback of the subducting plate and/or to isostatic crustal uplift. </p> 2016-06-21 11:43:33 kinematic model insight isostatic crustal uplift kinematic evolution extensional basins fault activity Tyrrhenian rift supradetachment basin subducting plate Stilo rift supradetachment basins Geology
