| Résumé anglais |
The following study is wholly concerned with the morphological problems posed by the linging-up of the different terraces on the lower Isère valley, along with either the retreat processes or the lateral overthrusts which complicate any attempt at correlation. Würm levels, first under study, allow one to elucidate the problem of the lateral sloping of certain terraces, then to find and explain why the maximum of würm levels remain only as very restricted outliers in the middle past of the valley (between St. Nazaire and the Herbasse valley) while spreading largely out both upstream (on the St. Marcellin terrace) and downstream (on the Tain terrace). For those terraces prior to Würm one is mainly confronted with the problem of the correlation of Châtillon St. Jean terrace. A detailed study will thus show that terrace links upstream at the level of the Fournel and downstream at the « intermediate » level of Marquet, situated further down on the Fouillouse Mindel terrace and higher up on the St. Marcel-lès-Valence Riss terrace, Source : Éditeur (via Persée) |
