Mesolite from
South Clunes United Mines, Clunes, Hepburn Shire, Victoria, Australia


Locality type:Mine
Classification
Species:Mesolite
Formula:Na2Ca2Si9Al6O30 · 8H2O
Comments:"Mesolite from South Clunes has been identified by X-ray diffraction on specimens in the Museum of Victoria collection. The mesolite forms a soft white crust of needles often completely lining the vugs in the basalt. It also forms small tufts and sprays of acicular crystals up to 1 mm long in several vugs. Phacolite twins, which have crystalized after the mesolite, are often found in the mesolite lined vugs."
