4300 Analcime, Fieldwicks Quarry, Lottah Road, Weldborough Pass, Tasmania

An interesting specimen with an analcime crystal on blue-grey saponite. The dark areas appear to be whatever material is sitting underneath the saponite. There are two other similar size analcime crystals in this vugh and all have the same thing underneath. Smaller analcime crystals in the vugh don’t. Collected by me.
