Surat Basin

The Suratbecken ( Surat Basin ) is a sedimentary basin in the Great Artesian Basin of Australia. It covers an area of ​​300,000 km, of which one-third in the northern part of New South Wales and the remaining portion in the southern central Queensland is.

Geology

The deposits of the basin, which spread fairly consistently over a large area, reaching a height of up to 2,500 m. In the Early Jurassic, the deposits made ​​by rivers. In the Middle Jurassic coal fields emerged, of which 100 have been discovered so far and about half of it is mined. In the north of the basin continued to imaginary river sediments and lakes and at the end of the Middle Jurassic again dominated alluvial deposits until deposed in the Cretaceous lacustrine deposits. In the Permian deposits of the underlying Bowen Basin were uplifted, not derived from lake sediment.

Economic use

The Suratbecken extends relatively evenly flat with a few small insignificant increases over the country. It is dominated by agriculture and mining use ( coal mining ). In sedimentary basins, there are also small gas fields that are not disconnected.

Also coalbed methane ( Coal Bed Methane ) is produced for the Australian market from the coal deposits. The gas is transported from the region about the Roma and Brisbane pipeline. It is intended in the future, even the presence of liquid in and around Gladstone to tap in order to serve the international market.
