This βunitβ represents two related and extensive Triassic-Jurassic olivine basalt flows covering 450 square km, highly dissected by erosion, and also intruded by some Tertiary alkaline igneous intrusives, including the Bulga complex.
They locally are highly vesicular with cavities to several metres in size (England, 1989). These commonly contain some important deposits of zeolites and other minerals, and at least 90 occurrences are known (England, 1989). Most of the best specimens have probably come from the Garrawilla and Mitchell creeks, on the Garrawilla, Glendowda and Mt Mitchell Stations, though there are over 90 similar zeolite locations in the area so itβs hard to be sure about individual specimens. Specimens have also been variously labelled as Tambar Springs (about 25 km away from Garawilla), Mullaley (35km), Coonabarabran (45km) and Gunnedah (60km). There have been similar zeolite occurrences found at Bald Hill, near Boggabri ( Chalmers, 1934). The minerals are listed and described under the above locations.
Collecting is generally forbidden by the property owners.
