Abstract

The existence of a southern polar ice cap through geologic time can be established by identifying asymmetries in the marine stratigraphic records of the Northern and Southern Hemispheres produced by the interaction of precession-scale sediment-yield cycles and glacially controlled sea-level cycles. Asymmetries should be manifested in the clustering of bed thicknesses and other stratigraphic properties. Hemispheric asymmetry should not exist in an ice-free world. To demonstrate the concept, this paper establishes the foundations for the hypothesis and presents the results of a statistical analysis of the synthetic stratigraphy of a tropical monsoonal area.
