Traces de volcanisme explosif dans le Campanien pyrénéen aux alentours du stratotype de limite Campanien-Maastrichtien à Tercis (SO France, N Espagne). Repérage biostratigraphique avec une étude particulière du foraminifère Radotruncana calcarata [Traces of explosive volcanism in the Pyrenean Campanian around the Campanian-Maastrichtian boundary type section at Tercis (SW France, N Spain). Biostratigraphy with emphasis on the foraminifer Radotruncana calcarata]

Pyroclastic material including idiomorphic crystals of sanidine, biotite, and apatite, first identified in the type section at Tercis are contemporaneous with the Radotruncana calcarata (planktonic foraminifer) total range zone. A search was undertaken to define the palaeogeographical extent and to...
