A: Structural map of the Kabylias and adjacent units, redrawn after Leprêtre et al. (2018), modified. Bd: Blida; GK/LK: Greater/Lesser Kabylia; Txn: Texenna. Blue heavy line: Kabylian thrust contact over Flyschs and Tell units. Red heavy line: thrust contact of the Tell units over Atlas foreland. − B: Map of the Dorsale units in Greater Kabylia (framed in A) after Cattaneo et al. (1999), modified. C, D: Upper Cretaceous onlap on faulted Liassic limestones in the External Dorsale, close to the Merkalla Lower Cretaceous basin. Perforations by benthic animals are shown on the onlap of the Globotruncana calcschists (courtesy J-P Bouillin, July 2022). E: Upper part of the stratigraphic series of the Median Dorsale in the Chellata massif, after Gélard (1979). F: Tagragra External Dorsale sliver (Pre-Dorsale type unit), after Coutelle (1979). G : Profile across Lesser Kabylia, after Raoult (1974), modified (see A for location).
