Late Precambrian paradoxal glaciation and obliquity of the Earth - A Discussion of dynamical constraints
G.E. Williams' observations on Late Precambrian glaciogenic sequences pose some major challenges to the understanding of the dynamical evolution of the Earth's orbit and spin that have not yet been adequately addressed. In this paper, we investigate whether dissipative core-mantle coupling is an effective mechanism for reducing the obliquity by such a large amount as suggested by Williams [G.E. Williams, Earth Sci. Rev. 112 (1993) 1-45], and we examine the relationship between the obliquity and...[Show more]
