The Cattamarra Coal Measures is an Early Jurassic geological unit in Western Australia.[1]
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.[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]
