Cited by Shopov in his papers about paleoluminescence;

Darapskite from Flower Cave, one of a group of caves located at the southern end of Big Bend National Park, Texas, U.S.A, does not fluoresce under short- or long-wave ultraviolet light; but the flower(darapskite+halite) phosphoresces green for approximately 5 seconds after irradiation with short-wave ultraviolet light.
