TGMS General Meeting - October 6, 2025
PLACE: 3727 E. Blacklidge Drive
TIME: 7:00 p.m. – Tucson, Arizona Time
WHEN: Monday, October 6, 2025
LECTURE: “Fluorescent Minerals of Bisbee” – Fluorescent Minerals are the least studied of the aspects of mineralogy, even post-mining minerals and radioactive minerals have been examined far more carefully from the locality. It took time for, in a sense, a more mature appreciation for minerals to develop for these minerals to be appreciated. They had to compete with species more obviously interesting, azurite, malachite and cuprite or, at the time, the strong economic interest in uranium minerals. Presently, 340 distinct mineral species have been identified from Bisbee; of these only 15 are recognized as fluorescent. We will look at the beginning of this interest and examine the species known and look at the future possibilities.
