Over 30 years ago, Crowell began
investigating the timing and synchronicity of Neoproterozoic glaciations on
Rodinian margins to understand the influence, interplay and implications of
tectonism and climate on the sedimentary record. This question is more topical
than ever with the implications of global catastrophic glaciation for the Earth
System. A popular conception of the Neoproterozoic record is that the presence
of discrete glacial intervals within a succession records an equal number of
discrete global climate events. This assumes synchronicity of glacially
influenced sedimentation in a time period with generally poor time constraints.
An alternative links regional tectonism with diachronous glaciation, connecting
uplift and adiabatic climate forcing. Data from the Kingston Peak Formation
