Progress Towards Correlating Palaeozoic French Strata with the International Stratigraphic Chart

Abstract

Palaeozoic rocks occur in France in geographically and geologically independent regions. They were deformed mostly during the Hercynian Orogeny. This work presents the first step of a larger project, which attempts to propose biostratigraphic correlations between the Phanerozoic formations of the different French regions and the International Stratigraphic Scale. The preliminary outcome reported here focuses on four regions containing Cambrian–Silurian strata: the Eastern Pyrenees, the Montagne Noire, and the Mid and North Armorican domains.
