Our September 13th program will be presented by the great Mr. Mike Fleeman on "Rocks from Space: A Study in the Different Types of Meteorite Falls.”   A timely program given the July 27th meteorite fall in Glendale, Arizona and fortunate discovery of an Ordinary Chondrite by Cody Horvath.

Mineral of the Month CHRYSOBERYL
Dr. Raymond Grant and Chris Whitney-Smith

Mineral of the Month for September is chrysoberyl, beryllium, aluminum oxide, BeAl2O4.  It is orthorhombic, has a hardness of 8.5, and is various shades of green, yellow, and brown in color. A special variety of chrysoberyl is alexandrite, which shows a distinctive green to red color shift from daylight to tungsten (artificial) light. Good quality faceted alexandrite is a valuable gem stone.

Chrysoberyl is a relatively rare mineral found in pegmatites and high grade metamorphic mica schist. It has been found in a couple of pegmatites in Arizona. Unfortunately, they are in the Northern Virgin Mountains, on the Arizona strip north of the Grand Canyon and not easy to visit. The Mineralogy of Arizona lists the locality as the Hummingbird Claims and Mindat has an additional listing for the Western Beryl Claims, but these are close to each other and even possibly adjoining claims. I was in that area many years ago looking for the chrysoberyl but did not have four-wheel drive, so never made it to the localities, but I was told that you could collect specimens.

Members are invited to bring one sample from their collection of the mineral of the month and give a brief story about where they collected it or something about the specimen.

***Unknown minerals for identification can still be brought to the meetings***

The Rules of Etiquette
From Rockhound Record 1942

At the risk of seeming impertinent, exhibitors of minerals will provide good insurance to specimens if they will display, in a prominent place on their exhibit, the rules of etiquette:

1. Never pick up a piece of material unless it is handed to you by the owner.

2. Always handle carefully – as many specimens are valuable and cannot be replaced.

3. If you cannot see the specimen well, ask the owner to show it to you.

Membership Dues are Due!

Please pay at the next meeting or mail to Mineralogical Society of Arizona, 5533 E. Bell Road Suite 101, Scottsdale, AZ 85254.
