Surat Basin

It comprises Jurassic through to Cretaceous aged sediments derived from Triassic and Permian arc rocks of the Hunter-Bowen orogeny.

Towns situated above the basin, once dominated by agriculture, are experiencing a boom as mines and infrastructure in the area are expanded.

The western central parts of the Surat Basin unconformably overlies the Palaeozoic igneous, metamorphic and sedimentary rocks of the Lachlan Fold Belt.

In the east and northern parts of Queensland it unconformably overlies the sedimentary basin rocks of the Hunter-Bowen Orogen.

It is unclear whether the thickness changes in the Walloon Coal Measures indicate a major erosional event (unconformity), or if the contact is only locally scoured.

[4] The basin has a number of coal seam gas (CSG) fields - also known as coalbed methane - developing in the region.

These fields presently supply both the domestic market, including a number of power stations and the Roma to Brisbane Pipeline, and Liquified Natural Gas (LNG) Plants located on Curtis Island near Gladstone to export Surat Basin gas to international markets.

Primary producers are especially concerned with the environmental and economic impacts of the Basin's development, Dalby , 2010
