The Cattamarra Coal Measures is an Early Jurassic geological unit in Western Australia. [1]
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. [2]
The Cattamarra Coal Measures constitute an unconventional tight gas reservoir. [3]
There are well preserved fossil insects from the Jurassic age in the deposit. [4]
