Geology Club to resume meetings on Thursday

September 18, 2021 at 4:00 a.m.

The Hot Springs Geology Club will resume its program meetings for local members or anyone interested in attending at 7 p.m. Thursday at the Arkansas School for Mathematics, Sciences, and the Arts, 200 Whittington Ave.

The program speaker will be a fellow club member, retired Arkansas Geological Survey geologist J. Michael Howard.

Howard's talk, "without using quantum physics," will describe the basics of fluorescence -- what it is, and why it happens.

"Of the known over 5,500 minerals, at least 443 are known to fluoresce," a news release said.

"Also, there are a few minerals, some glasses and some common objects, like clothing, that fluoresce different colors in either short wave and long wave ultraviolet light. We will explain the differences between short wave and long wave UV. There is also a second type of shortwave UV that has significant commercial uses, which will be discussed Thursday.

"The highlight of the presentation will be the examination of a number of different fluorescent minerals and glass samples, in a darkened room. If you have not seen minerals or glass under a UV lamp, then be prepared to be amazed! After all, where do you think the term fluorescent paint came from?" the release said.

Howard will also bring a few books and reference sources for anyone interested in further reading on the topic.
