Tertiary basalts outcrop over a large area in the vicinity of Gads Hill that lies between Mole Creek and Moina in the northwest of
Tasmania. There are two main collecting sites, although with some searching, more should be found.
Road cuts through the basalt have some very large vesicles containing abundant zeolites.
