During periglacial times, weathering probably depends on melted snow or ice as the principal source of water and on the atmosphere as the source of 02 and C02. During glacial times, though, volatiles required for weathering might be derived from gas bubbles or clathrate ices that form in the ice at depths of 900-1300 m [9]. fast genial benedict wells
