Preliminary investigations of an Aptian GSSP candidate at the historical Bedoulian locality near Cassis (Bouches-du-Rhône) and complementary section at the stratotype Barremian locality at Angles (Alpes-de-Haute-Provence)

Carnets Geol.
This report presents preliminary investigations of a new candidate for the Aptian Global boundary Stratotype Section and Point (GSSP) at Cassis (Bouches-du-Rhône, France), within the historical Bedoulian stratotype area, and a complementary section at Angles (Alpes-de-Haute-Provence, France). Fieldwork in 2025 identified a promising continuous section (
