Changes of the orbital (Milankovitch) parameters and their influence on paleoclimate, paleoceanology, and sedimentology during times of global warmth

...为了研究这种关系，我们建议进行气候模拟，探讨轨道变化对几个白垩纪古地理和大气成分的影响。...最近的研究主要集中在极端轨道构型对沉积偶层形成的影响上。G.泥灰页岩和石灰岩）。上南极洲的新气候模拟（Flögel等人，提交的报告）表明，这两种极端的中间轨道构型都可能造成气候系统的重大区域和全球变化。初步研究表明，这些可能确实是有节奏的层状沉积物的原因。之前对白垩纪古气候学的研究主要集中在晚白垩纪地层，但对于这项研究，我们计划将调查扩展到早白垩纪，那里的米兰科维奇旋回保存得非常好。

... 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.
