The Cattamarra Coal Measures is an Early Jurassic geological unit in Western Australia.
Description
They are part of the Perth Basin, and are a sequence of non-marine, probably fluvial sandstones, shales and silts including bituminous coal, and are up to 300 m thick. The Cattamarra Coal Measures conformably overly the Eneabba Formation.
The Cattamarra Coal Measures constitute an unconventional tight gas reservoir.
There are well preserved fossil insects from the Jurassic age in the deposit.
