Encyclopedia Article for gibber

rock- and pebble-littered area of arid or semi-arid country in Australia. The rocks are generally angular fragments formed from broken up duricrust, usually silcrete, a hardened crust of soil cemented by silica (SiO2). The gravel cover may be only one rock fragment deep, or it may consist of several layers buried in fine-grained material that is thought to have been blown in. A gibber is generally considered a result of mechanical weathering because silica is almost inert to chemical weathering.
