Nullarbor Plain

From Simple English Wikipedia, the free encyclopedia
Nullarbor is the light tan semi-circular area near the coastline, 2002
Murrawijinie cave system seen from inside. It is a karst system, formed by water running through the limestone. Murrawijinie means "bloody hands": the caves were used by indigenous people who left their ochre hand stencils on the cave walls

Nullarbor Plain (Latin: nullus, "no", and arbor, "tree") is an area of flat, dry land in southern Australia on the coastline of the Great Australian Bight.

It is the world's largest single piece of limestone, and occupies an area of about 200,000 square kilometres (77,000 sq mi).[1] At its widest point, it stretches about 1,100 kilometres (684 mi) from east to west between South Australia (SA) and Western Australia (WA).

As to what causes these huge and distinctive limestone areas, no-one knows. Perhaps it is significant that one of the best-known area, the Yukatan, was in or near a hit by a huge meteorite. As much as 50% of the world's hydrocarbon reserves are in carbonate rock, and much of this is in porous karst systems.[2]
