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!

A Beautiful Midwestern Fluorescent Classic- Celestine, Strontianite and Calcite from the Stoneco Lime City Quarry

minID: HAM-81Y

Locality: Stoneco Lime City Quarry, Lime City, Wood County, Ohio, USA (See on Mindat)
Size: 39 x 34 x 61 mm
Weight: 74 g

Description:
This is a matrix-free cluster of blocky white celestine crystals, partially altered to strontianite, and honey-colored calcite scalenohedrons, collected from the Stoneco Lime City quarry in Lime City, Wood County, Ohio. This specimen shows a similar bright blue/white, fluorescent response under all UV wavelengths, and also exhibits strong phosphorescence after UV.

Situated in deposits of the Lockport and Greenfield dolomites, the Lime City quarry was a producer of building stone and a prolific source of specimens during the 1960s and 1970s. The specimen-producing areas of the quarry are now covered with tailings and the quarry is mostly flooded with water. Although the quarry has been closed to collecting for decades, fine specimens can still be found at mineral shows in the Midwestern US.
