Abstract
The Flysch di Solignano was deposited in a basin plain below the CCD close to the western margin of the Ligurian Tethys during Early Maastrichtian.The siliciclastic supply was mainly delivered by a crystalline basement of Sardinian-Corsican affinity. The carbonate supply, made up ofpelagic ooze, derived by oceanic intrabasinal structuralhighs represented by transform prisms uplifted within the compressive field affecting the Ligurian domain during Late Cretaceous. Resedimentation processes were likely triggeredby tsunami waves generated by high-magnitude earthquakes on this confined arm of the Ligurian Thethys.The hypothesis that resedimentation processes not only affected coeval pelagic ooze but also the underlying unconsolidated oceanic sediments of the Cretaceous oceanic coverComplessi di Base) is put forward.File | Dimensione | Formato | |
