p.19: The Autochthonous North Alpine Foreland consists of the European platform with its Cenozoic graben structures of eastern France, southwestern Germany and northern Switzerland (e.g., Illies 1981, Eisbacher et al. 1989). The boundary between the Autochthonous North Alpine Foreland and the Detached North Alpine Foreland marks the northernmost limit of significant Alpine compressional deformation.
Accordingly, the Autochthonous North Alpine Foreland is widely absent [sic; >>> deprived] of map-scale compressional structures; small-scale compressive structures however occur in the southern marginal area (Dèzes et al. 2004, Madritsch et al. 2008). According to microscopic strain analyses, the effects of Neogene Alpine deformation extend hundreds of kilometers out into this domain (Craddock et al. 2022 and ref. therein).

The N–S trending Bresse Graben (a segment of the European Cenozoic Rift System) is ca. 35–60 km wide and stretches roughly from Lyon to Dijon. It is clearly separated from the Haute-Saône Platform by NNE–SSW to NE–SW oriented normal faults.
The Bresse Graben is filled with Paleogene–Neogene sediments which are up to 2 km thick.

The Haute-Saône Platform forms the southeastern rim of the Paris Basin and is formed predominantly by Mesozoic sediments, with some post-rift Neogene Molasse sediments. It is mostly located in France except for the Ajoie area. At its eastern boundary, the separation from the northern part of the Upper Rhine Graben is clearly defined by NNE–SSW trending normal faults. In the south, however, the situation is more complex. Here, the limestone plateau of Ajoie, regarded as belonging to the Haute-Saône Platform, is separated from the northward-adjacent Upper Rhine Graben by a W–E trending flexure dissected by N–S trending normal faults. To the south, the Haute-Saône Platform is mostly bounded by the Detached North Alpine Foreland, in particluar by the frontal Faisceaux of the External Folded Jura. South of the Ajoie area, where the External Folded Jura is missing, the Internal Folded Jura is thrust directly onto the Haute-Saône Platform.

The Vosges Massif exposes the basement of the Haute-Saône Platform. It consists of pre-Mesozoic rocks, including Variscan magmatites and metasediments, pre-Variscan metamorphic rocks and, on the southwestern side of the Upper Rhine Graben, unconformably overlying Permo-Carboniferous sediments.

The NNE–SSW trending Upper Rhine Graben (a segment of the European Cenozoic Rift System located north of Basel) is up to 40 km wide and separates the Haute-Saône Platform to the west from the South German Platform to the east. The graben shoulders are bounded by steep normal faults and include isolated, lowered blocks of Mesozoic platform sediments along the rift-internal sides (the so-called Vorberg Zone, e.g., Isteiner Klotz north of Basel). The Schwarzwald Fault forms the eastern border of the graben. The southwestern border of the graben with the Haute-Saône Platform forms a flexure. In the southeast, the graben borders the External Folded Jura; the corresponding flexure is accentuated and overprinted by Alpine deformation.
The Upper Rhine Graben is filled with Paleogene–Neogene sediments of 2–3 km thickness.
