Revealing the Internal Structure of Mars-Analog Glaciers From Drone-Based Radar Sounding
Debris-covered glaciers (DCGs) at the mid latitudes of Mars preserve ice accumulated in multiple episodes of high obliquity during the Amazonian age. The englacial debris layers formed during interglacials are […]

Three-stage Formation of Cap Carbonates after Marinoan Snowball Glaciation Consistent with Depositional Timescales and Geochemistry
At least two global “Snowball Earth” glaciations occurred during the Neoproterozoic Era (1000-538.8 million years ago). Post-glacial surface environments during this time are recorded in cap carbonates: layers of limestone […]
