Feb 1, 2023 · Introduction. During the mid-Cretaceous, significant global perturbations in paleoceanographic, paleoenvironmental, and paleobiological events took place in response to the activity of large igneous provinces and oceanic crustal production, which resulted in extraordinary emissions of atmospheric carbon dioxide (Jenkyns, 2010). The Cretaceous palaeoclimate system was evidently much more variable and complex than expected for a theoretical Greenhouse world (Ladant and Donnadieu, 2016; Rodríguez-López et al., 2016). Aeolian deposits constitute one of the most valuable climate-sensitive sedimentary environments that can help to advance in the understanding of …Abstract and Figures.
