January 10, 2019 Program: “Mysteries of the Mineral Kingdom Revealed: Collecting Radioactive Minerals.” Presented by Mr. Dick Zimmermann

Our January 10th program will be presented by Dick Zimmermann on “Mysteries of the Mineral Kingdom Revealed: Collecting Radioactive Minerals.” The program will briefly review the cause of radioactivity, means of detecting it, the natural occurrence of natural radioactive minerals in the earth’s crust,
and safe handling procedures.  Detailed descriptions of natural radioactive minerals that can be collected will follow, along with explanations of why most of them contain uranium, thorium, or potassium. Although many radioactive minerals, especially those from the southwestern USA, are quite unattractive, some do form exquisite, unique, and colorful crystals.  The program will include many illustrations of such attractive radioactive crystals.

Dick Zimmermann is a retired aerospace engineer who has collected minerals in the southwestern USA for the past 40 years.  He actively supported the Arizona Mining and Mineral Museum and various earth science education projects.


He has prepared presentations on special topics like pegmatites, pseudomorphs, ore deposits, geodes, scepters, and the various colors of wulfenite for various clubs and for the annual Minerals of Arizona Symposium hosted by Flagg Mineral Foundation. 




Mineral of the Month: CYANOTRICHITE - Cu4Al2(SO4)(OH)12 · 2H2O By Dr. Ray Grant and Chris Whitney-Smith

Mineral of the Month for January is cyanotrichite, Copper aluminum sulfate hydroxide hydrate, Cu4Al2(SO4)(OH)12×2H2O.
 A rare secondary mineral associated with other oxidized copper minerals. It is sky-blue to azure-blue and occurs as needle like crystals in spheres, tufted aggregates, and plush coatings. There is a similar mineral carbonatecyanotrichite, Cu4Al2(CO3)(OH)12×2H2O that looks identical and the two cannot be identified except by x-ray work.

Cyanotrichite has been found in Arizona at Morenci, Jerome, and Maid of Sunshine Mine near Courtland. Both cyanotrichite and carbonatecyanotrichite are found at Bisbee and the Grandview Mine, Grand Canyon National Park.

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.
Membership form & dues amounts are on website under MSA CLUB tab.
