Approximately 4,000 different mineral species have been identified at this time. Over 500 of them are known to fluoresce visibly in some specimens. Dino Zack, PG, will discuss the various types of luminescence with a detailed explanation of mineral fluorescence.

Fluorescent rock and mineral specimens from New York State, as well as world-know locations, will be on display and used to demonstrate the many types of luminescence including fluorescence, phosphorescence, triboluminescence, thermoluminescence, and tenebrescence.

An illustrated presentation with mineral specimens, in the auditorium of the Gateway Executive Office Building, 3556 Lake Shore Rd., Blasdell, NY 14219.
