Gloss. geol.(ice cap: a dome-shaped or platelike cover of perennial ice and snow, covering the summit area of a mountain mass so that no peaks emerge through it, or covering a flat landmass such as an Arctic island; spreading due to its own weight outwards in all directions; and having an area of less than 50,000 sq km. An ice cap is considerably smaller than an ice sheet. Non-preferred syn.: ice carapace. Also spelled: icecap)
Concise Ox. dict. earth sciences, 1990(ice-cap: Ice mass less than 50,000 sq km in area, but large enough to submerge the underlying topography and whose flow behaviour is a consequence of its size and shape. It consists of a central ice dome together with outlet glaciers radiating from the periphery.)
