... interpreted the South Ophiolite Belt as a northerly derived tectonic klippe rooted in the North Ophiolite Belt (Kapp et al., 2003; Kapp and DeCelles, 2019), or as a tectonic boundary within the Lhasa Terrane (Pan et al., 2004; Zhu et al., 2013). However, the two subbelts contain flysch and ophiolites...

... formations (BIMFs) and/or large blocks embedded in layered flysch sequences in the sedimentary record of ancient collisional belts ( Festa et al. 2016 ). As the formation of these sedimentary basins is coeval with propagation of the orogeny towards the passive margin, they provide key constraints...

... as flysch units with a broad age range (Triassic–Paleogene) and limited biostratigraphic age control (e.g. Brunnschweiler 1966 ; Bannert et al. 2011 ). At the time of our fieldwork (2016), access to some parts of the Rakhine coastal area was prohibited or restricted. Road-building has created some new...

... stockwork. Three broad lithostratigraphic groups occur in the regional stratigraphy: the phyllite-quartzite group, the volcano-sedimentary complex, and the Baixo Alentejo Flysch Group. These three major packages reflect the evolution of a depositional environment from a stable platform to deposition in pull...

.... In northern Tunisia, the Numidian Flysch can be subdivided into three members: the Zouza, Kroumirie, and Babouch members ( Fig. 1 ; Rouvier 1977 ; Torricelli and Biffi 2001 ; Riahi et al. 2010 ). The sampled beds under investigation are located at the northeastward-jutting headland Cap Serrat, along...

... by gravitational currents into deep basins. Such phenomena played important roles in accumulation in the Carpathian Basins, a part of the western Tethys Ocean along the southern slopes of the European platform. Spiculitic deposits formed thick bodies in the mid-Cretaceous flysch of the Silesian nappe. This study...

..., for example, along major fault zones. In addition, the 87 Sr/ 86 Sr ratios of vein carbonates can trace the diagenetic to metamorphic evolution of pore fluids in accreted sediments. Here we present 87 Sr/ 86 Sr ratios of vein carbonates from the Infrahelvetic flysch units of the central European Alps (Glarus...

... deposits (mixed successions) of the “Mérinides Facies” from the “Maghrebian Flysch Basin” and the “Beliounis Facies” from the Predorsalian Unit. Our petrographic analyses and detrital zircon U-Pb ages show that the quartzarenites of the “Numidian Facies” originated from the African Craton, whereas...

... of the distal depositional domain of the Bordighera Sandstone (BGS). In its distal domain, the sand-rich Bordighera turbidite system is characterized by direct interbedding with calcareous fine-grained turbidites of the Sanremo Helminthoid Flysch, and features high proportions of HEBs and TFDs. Analysis...

Olistoliths are arranged parallel to the flysch layering and thrusts. The results presented confirm the postulated two olistostrome belts within the PKB...
