New Perspectives on Glacial Geomorphology in Earth’s Deep Time Record

The deep time (pre-Quaternary) glacial record is an important means to understand the growth, development, and recession of global cryosphere on very long timescales (10 6 –10 8 Myr). Sedimentological description interpretation outcrops has traditionally played role. Whilst such data remain vital, new insights are now possible thanks freely accessible aerial satellite imagery, widespread availability affordability Uncrewed Aerial Vehicles, accessibility 3D rendering software. In this paper, we showcase examples glaciated landscapes from Cryogenian, Ediacaran, Late Ordovician Carboniferous where approach revolutionizing our understanding glaciation. Although some problems cannot be overcome (erosion or dissolution evidence), robust interpretations in terms evolving subglacial environment can made. Citing Australia (Cryogenian), China (Ediacaran), North South Africa (Late Ordovician, Carboniferous), Namibia illustrate how power geomorphology harnessed interpret Earth’s ancient record.
