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