Biostratigraphy and structure of the Voirons Flysch: Gurnigel Nappe, Haute-Savoie, France
The Voirons Flysch (Haute-Savoie, France) is the subject of the present research. In this study we propose (i) a refined age model based on planktonic foraminiferal biostratigraphy, (ii) the extension of the reworking process and (iii) a structural study suggesting an updated tectonic model for this...
