An unusual specimen. I am unaware of other zeolite specimens from Sunbury, although the basalt quarries do produce calcite and aragonite. This specimen also has what looks like calcite-coated prismatic augite crystals, unlike any other Victorian zeolite localities I have seen.
Perhaps the most surprising aspect of this specimen is the reaction to shortwave ultraviolet. The pink is calcite, but the phillipsite is pale blue!
Specimen is 44x35x25mm. Photos taken with iPhone 11 Pro Max.
