Tirari–Sturt Stony Desert
The Tirari–Sturt stony desert is a deserts and xeric shrublands ecoregion in central Australia. Location and description The Tirari–Sturt stony desert ecoregion contains the gibber plains (desert pavement) and red sands of the large Sturt Stony Desert, the Tirari Desert to its southwest and the Flinders and Gawler Ranges to the south. The Tirari has more sand dunes than the Sturt Stony Desert and has also been the site of some important fossil findings. Towns of the ecoregion include the opal mining centre of Coober Pedy, famous for its underground dwellings. The climate is very hot with summer temperatures reaching 50 °C. The region consists of the Stony Plains, Gawler, Flinders Lofty Block and the Broken Hill Complex bioregions of the Interim Biogeographic Regionalisation for Australia (IBRA).

Gawler Range
The Gawler Ranges are a range of stoney hills in South Australia to the north of the Eyre Peninsula. The Eyre Highway skirts the south of the ranges. The Gawler Ranges National Park is in the ranges north of Kimba and Wudinna. The ranges are covered by the Gawler Ranges Native Title Claim. History The traditional owners of the Gawler Ranges are the Barngarla, Kokatha and Wirangu peoples, who have inhabited the area for at least 30,000 years and are now known collectively as the Gawler Ranges Aboriginal People. These Aboriginal peoples maintained and used rock holes in the granite rock formations as a water source. The ranges were named by Edward John Eyre after the Governor of South Australia, George Gawler in 1839. This was on one of Eyre's earlier expeditions before his famous crossing of the Nullarbor Plain further west. It was on this expedition that Edward John Eyre made the first recorded sighting of South Australia's floral emblem, the Sturt desert pea, in 1839 durin ...

Gibber Plain
A desert pavement, also called reg (in western Sahara), serir (in eastern Sahara), gibber (in Australia), or saï (in central Asia) is a desert surface covered with closely packed, interlocking angular or rounded Rock (geology), rock fragments of pebble and cobble (geology), cobble size. They typically top alluvial fans. Desert varnish collects on the exposed surface rocks over time. Geologists debate the mechanics of pavement formation and their age. Formation Several theories have been proposed for the formation of desert pavements. A common theory suggests that they form through the gradual removal of sand, dust and other fine-grained material by the wind and intermittent rain, leaving the larger fragments behind. The larger fragments are shaken into place through the forces of rain, running water, wind, gravity, creep, thermal expansion and contraction, wetting and drying, frost heaving, animal traffic, and the Earth's constant microseismic vibrations. The removal of small ...
