Wollastonite

 Wollastonite with Ferroanbustanite, andradite, and diopside from Eaglehawk Reef, Union Mine, Maldon, Victoria (Scale: 10 cm)

Wollastonite's (CaSiO3) hardness, whiteness, mineral structure and chemical inertness are all properties that are useful for fillers in paint, rubber, plastics, adhesives and ceramic-bonded abrasives.

In Victoria wollastonite has been found mostly as a minor constituent of skarns. The limestone bodies that have been altered to skarns appear to have been small and impure. There is little economic potential for wollastonite in the State.

The most important wollastonite mineralisation in skarns in Victoria includes contact-metamorphic aureoles of the Suggan Buggan Granodiorite northeast of Wulgulmerang, the Snowy River Volcanics on the Buchan River west of Wulgulmerang, the Strathbogie Granite north of Bonnie Doon, the Harcourt Granite in the Union Mine at Maldon and at Blue Mount, Toolangi.
