Registro geológico del máximo térmico del Paleoceno-Eoceno en el Parque Nacional de Ordesa y Monte Perdido (Pirineo Central)
The Paleocene-Eocene thermal maximun (PETM) had earlier been documented in basinal and continental settings of the Pyrenean basin clastic units. In this work new data are added from comparatively less well-known platform interior successions outcropping at the Ordesa and Monte Perdido National Park....

| Sumario: | The Paleocene-Eocene thermal maximun (PETM) had earlier been documented in basinal and continental settings of the Pyrenean basin clastic units. In this work new data are added from comparatively less well-known platform interior successions outcropping at the Ordesa and Monte Perdido National Park. There, the PETM is recorded by comparatively thin (10-30 m) but laterally extensive accumulations of siliciclastic deposits that are thought to represent an ancient wave- and storm-dominated delta system. Further, the landward pinch-out of the delta suggests that the PETM occurred during an interval of relatively low sea level. Together with other siliciclastic units of the Pyrenean domain, the new data confirms the intensification of the hydrological cycle during the PETM |
