Surat basin

from Wikipedia, the free encyclopedia

The Surat Basin ( Surat Basin ) is a sedimentary basins in the Great Artesian Basin of Australia . It covers an area of ​​300,000 km, of which a third is in the northern part of New South Wales and the remainder in south-central Queensland .

geology

The deposits of the basin, which spread fairly continuously and over a large area, reach a height of up to 2,500 m. In the early Jurassic , the deposits were made by rivers. Coal fields emerged in the Middle Jurassic, 100 of which have been discovered so far and around half of them are being mined. In the north of the basin, river deposits and lakes continued to form and at the end of the Middle Jura river deposits dominated again until lake deposits settled in the Cretaceous period . In the Permian , deposits from the Bowen Basin below were lifted that did not come from lake deposits.

Economic use

The Surat Basin extends relatively evenly flat with a few insignificant small elevations over land. It is characterized by agriculture and mining (coal mining). There are also small gas fields in the sedimentary basin, but these are not being dismantled.

Also is from the coal coalbed methane ( coal bed methane ) won for the Australian market. The gas is transported out of the region via the Roma and Brisbane pipelines. In the future, the intention is to develop the liquid gas deposits in and near Gladstone in order to serve the international market.
