Multistage tectono-stratigraphic evolution of the Canavese Intracontinental Suture Zone:New constraints on the tectonics of the Inner Western Alps
文献摘要:
The Canavese Intracontinental Suture Zone(CISZ)within the Inner Western Alps represents the remnant of a long-lived minor subduction zone involving a narrow,thinned continental crust/oceanic lithosphere seaway between two continental domains of the Adria microplate(i.e.,the Sesia Zone and the Ivrea-Verbano Zone).As opposed to many suture zones,the CISZ mostly escaped pervasive tectonic deforma-tion and metamorphism,thus preserving the original stratigraphy and allowing the relationships between tectonics and sedimentation to be defined.Through detailed geological mapping(1∶5000 scale),structural analysis,stratigraphic and petrographic observations,we document evidences for the late Paleozoic to late Cenozoic tectonic evolution of the CISZ,showing that it played a significant role in the context of the tectonic evolution of the Inner Western Alps region from the early to late Permian Pangea segmentation,to the Jurassic Tethyan rifting,and up to the subduction and collisional stages,forming the Western Alps.The site of localization/formation of the CISZ was not accidental but associated with the re-use of structures inherited from regional-scale wrench tectonics related to the segmentation of Pangea,and from the subsequent extensional tectonics related to the Mesozoic rifting,as documented by crosscutting relationships between stratigraphic unconformities and tectonic features.Our findings document that evidences derived from stratigraphy,facies indicators,and relationships between tecton-ics and sedimentation in the shallow crustal portions of suture zones,such in the CISZ,are important to better constrain the tectonic history of those metamorphic orogenic belts around the world in which evo-lutionary details are commonly complicated by high-strain deformation and metamorphic transformations.
