dc.description.abstractThe Iberian Chain developed by inversion of Mesozoic rifts of the Iberian Basin during the Paleogene. The Maestrat and Cameros basins developed during the Late Jurassic-Early Cretaceous rifting cycle 2. There are two main controls on sedimentation: (1) tectonics, (2) climate, and these together control sea-level and paleoecosystems. Cameros and Maestrat basins display different styles of extensional tectonic structure probably due to a crust thermally weakened. Biotic changes in freshwater plants, continental faunas, and marine carbonate producers, reveal the evolution from Late Jurassic-Earliest Cretaceous climate to show hydrological seasonality in a general warm and humid context. This is confirmed by the coexistence of biotic markers of hydrological stress (closed stomatal structures in plants, small size in animals) with sedimentologic indicators of a long-lasting humid climate (lateritic soils and karstic bauxite deposits). The long-term global sea-level curve fits the main transgressive-regressive evolution of the Maestrat basin with some local tectonic disturbancesen_US
