General Information

The presence of the Sardic Phase and associated Middle Ordovician stratigraphic gaps has been reported in the Eastern Pyrenees, the Mouthoumet massif and the Cabrières klippes of the southern Montagne Noire. Late Ordovician fault-controlled subsidence and the record of rifting volcanism were coeval, in some areas, with the onset of the Hirnantian glaciation. As a result, the Upper Ordovician of SW Europe offers a complex mixture of erosive unconformities and intrusion of acidic plutons  (Pyrenees), followed by the breakdown of platforms in horsts and (half-)grabens and the onset of rifting branches (Mouthoumet and Montagne Noire), onlapping patterns and final sealing of Sardic palaeotopographies during Silurian and Early Devonian times.

The meeting addresses the dynamics of Lower Palaeozoic (Cambrian-to-Silurian) sedimentary basins and aims to bring together a wide range of studies focusing on geodynamics, tectonics, volcanism, sedimentary geometries, event stratigraphy and chronostratigraphic correlation. We aim to balance the study of geodynamic processes recorded throughout North Gondwana (SW Europe) with worldwide analogues.  
We welcome all contributions integrating Lower Palaeozoic geodynamic discussions, including volcanic, structural and (chrono)stratigraphic data.
