Radiolarians and Tethyan Radiolarites from Primary Production to their Paleogeography

摘要: Paleogeography is established using mainly plate kinematics and unfolding mountain belts, but basinal paleodepths are defined specific facies, among which radiolarites can provide key information. The common equation = deep oceanic basin obviously too simple to be correct; infer from the geological message (e.g., radiolarites), original, environmental, biological signal requires a good knowledge of successive filters that have changed it originators these signals radiolarians).
