THE BATHONIAN-CALLOVIAN ZOOPHYCOS SERIES OF THE CASTELLANE ARC (SOUTH-EASTERN FRANCE) IN THE PLATFORM-BASIN TRANSITION ZONE - STRATIGRAPHY AND PALAEOTECTONICS

The Bathonian-Callovian marl-limestone alternations of the Castellane Are, known as ''Calcaires a Cancellophycus'' Formation, have been stud ied in the transition zone between the Provencal platform and the Daup hinois basin. We propose to name this Formation '' Calcaires a Zoophyc os du Verdon''. Its age varies from Lower Bathonian to Middle Callovia n. The rapid strong thickness variations of such series are explained by tilted-block dynamics. We propose a palaeotectonic reconstruction f or the Bathonian-Callovian period.
