Fluorescent Mineral Database

A new secret project! Trying to create a nice Fluorescent Mineral Database (FMDB), which would be searchable by mineral, locality, and luminescence properties. Also making it easy for people to contribute with their own specimens!

Willemite and Dolomite from the Aroona Zinc Mine, Flinders Ranges, South Australia

Description:
Swirling veins of fluorescent willemite (green) and dolomite (red) dominate this specimen from the Aroona Zinc Mine, Leigh Creek, Flinders Ranges, South Australia. The Aroona Mine is located approximately 11 km to the NW of the better known Puttapa Zinc Mine, another location that has produced many spectacular fluorescent mineral specimens from Australia. This specimen has bright and long-lasting green and blue phosphorescence/afterglow following exposure to shortwave UV (254 nm).
