The Tyrrhenian Basin is a region created by Neogene extensional tectonics related to slab rollback of the east-southeast–migrating Apennine subduction system, commonly believed to be actively underthrusting the Calabrian arc. A compilation of >12,000 km of multichannel seismic profiles, much of them recently collected or reprocessed, provided closer scrutiny and the mapping of previously undetected large compressive structures along the Tyrrhenian margin. This new finding suggests that Tyrrhenian Basin extension recently ceased. The ongoing compressional reorganization of the basin indicates a change of the regional stress field in the area, confirming that slab rollback is no longer a driving mechanism for regional kinematics, now dominated by the Africa-Eurasia lithospheric collision

第勒尼安盆地的最新反演

第勒尼安盆地是由新近纪伸展构造所形成的区域，与东-东南-迁徙的亚平宁俯冲系统的板坯回滚有关，通常认为该活动正在积极地推动卡拉布里亚弧。汇编了> 12,000 km的多通道地震剖面，其中许多是最近收集或重新处理的，这提供了更严格的检查以及沿第勒尼安河边缘先前未发现的大型压缩结构的映射。这一新发现表明第勒尼安盆地扩展最近停止了。盆地正在进行的压缩重组表明该地区的区域应力场发生了变化，这证实了板坯的回滚不再是区域运动学的驱动机制，而非洲-欧亚大陆岩石圈碰撞已成为主导
