Ngalia Basin

The Ngalia Basin (English: Ngalia Basin ) is a small approximately 15,000 km ² large sedimentary basins of the Australian craton ( continental core ) in the south of the Northern Territory of Australia.

In the sedimentary basins are located about 6 km thick marine and non- marine deposits that originated from the Neoproterozoic to Carboniferous 1000-300 million years ago. The located in the basin rocks are limestone, mudstone, siltstone, quartzite and glacial sediments. With the other nearby sedimentary basins, the Amadeus Basin, Georgina Basin and Officer Basin, all of which originated in the same period, it should once have been part of the Centralian Superbasin in Australia that has been fragmented by different sequences of tectonic activities.

The basin contains significant deposits of uranium that were mineralized in sandstone deposits and there are deposit exploration for oil and natural gas instead.
