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!

Miserite and Wollastonite - Arkansas

Contributed by: Mark Cole
Date: Mar 19th, 2026
Locality: North Wilson pit, Union Carbide Mine, Wilson Springs (Potash Sulfur Springs), Garland County, Arkansas, USA (See on Mindat)

Description:
UPDATE: The original post listed the locality as Magnet Cove. However, the mineral assemblage and fluorescence behavior strongly point to the North Wilson Pit as the more precise source. Located just west of the main Magnet Cove complex, the North Wilson Pit (also referred to as the Wilson Springs area) is the only confirmed locality in Arkansas for miserite.
