... In order to investigate this relation we propose to conduct climate simulations to explore the effects of orbital variations on several Cretaceous paleogeographies and atmosheric compositions. ... Recent studies have focused on the influence of extreme orbital configurations on the formation of sedimentary couplets (e. g. marly shales and limestones). New climate simulations for the Upper Cretacous (Flögel et al., submitted) show that both extreme intermediate orbital configurations can cause major regional and global changes of the climate system. Preliminary studies suggest that these may indeed be the cause of the rhythmically bedded sediments. Prior studies of the paleoclimatology of the Cretaceous have focused on the Late Cretaceous strata, but for this study we are planning to extend the investigations into the Early Cretaceous, where Milankovitch cycles are extremely well preserved.
