Great Artesian Basin/Aquifer
About 225-65 million years ago quartzose sandstone formations began to take shape which created what we call today, The Great Artesian Aquifer/Basin. Covering an area of about 1,700,000 Kilometers (1,065,351 miles) and containing about 64,000 million mega litres of water or roughly enough to fill the Sydney harbor about 130,000 times. The depth varies very greatly between 300 and 9,000 feet. It is located beneath the arid to semi-arid interior of Queensland, New South Wales, South Australia, and the Northern territory. It has multiple concentrations of springs covering manly small areas around the edge of the Basin. It recharges itselfeastern margins of the GAB where the main sandstone aquifers outcrop in upland areas which experience high rates of precipitation.
It has particles of NA-CI-SO4 and NA-CA-SI-SO4 which are, in other words, the things that give the water it’s salinity. The salinity also increases around the edges. Some interesting facts about the aquifer is that it is the largest aquifer in not only Australia but the world. It also contains the oldest water in the world.
