Thanks for sharing! Caused by glacial erosion, the "freezing" of sediment deposition by ice coverage, or both? Are there any estimates on glacial thickness or "heat map" of thicknesses across Pannotia?

Erosion, and for that wet-based ice would be key, so thickness is quite important. Yes! There are a number of estimates on this from icesheet modelling; check out for example Fig. 5 in Donnadieu et al. 2003 [1] [1] https://doi.org/10.1016/S0012-821X(02)01152-4 https://doi.org/10.1016/S0012-821X(02)01152-4
