p.20: The Haute-Saône Platform, which forms the southeastern rim of the Paris Basin, occupies the northwestern corner of the map area. 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 (Ustaszewski et al. 2005).
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 (see § 3.2). 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 Haute-Saône Platform is formed predominantly by Mesozoic sediments, which are strongly intersected by N–S to NNE–SSW oriented faults associated with the Paleogene development of the European Cenozoic Rift System (Lacombe et al. 1993). Some post-rift Neogene Molasse sediments can be found south of the lower reaches of the Ognon River that follows a major ENE–WSW trending fault associated with the transfer zone between the Upper Rhine and the Bresse graben structures (Madritsch et al. 2009).

    In short

    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.
