Caprock, or cap rock, is a harder or more resistant rock type overlying a weaker or less resistant rock type. Common types of caprock are sandstone and ultramafic rock types. In processes such as scarp retreat, the caprock controls the rate of erosion of the scarp. Photo © copyright by Robert Faucher.
