June 14, 2018 Program: "Mysteries of Mineral Kingdom Revealed: Micromount Minerals of 79 Mine" Presented by Mr. Ron Gibbs

Our June 14th program will be presented by the great Mr. Ron Gibbs on "Mysteries of Mineral Kingdom Revealed: Micromount Minerals of 79 Mine."  Ron’s program will address history of 79 Mine and then go through the various mineral groups found in the mine illustrated with photos of microminerals showing the diversity of habit and form not usually seen by the collector.  This will be great opportunity to peer into rich mineral diversity of a legendary Arizona mine from a well-respected mineral research professional, author and lecturer.

Ron has been interested in rockhounding since high school and began focusing on minerals in college. He enjoys collecting all sizes of specimens including microminerals.  Ron has degrees from Humboldt State College and Mackay School of Mines (University of Nevada Reno).  He retired after 37 years working for Phelps Dodge, now Freeport McMoRan.

Mineral of the Month BOLEITE
Dr. Raymond Grant

Mineral of the Month for June is Boleite, potassium lead copper silver chloride hydroxide, KPb26Ag9Cu24(OH)48Cl62.  It is cubic, color is dark blue, and the hardness is 3 – 3.5.  The best way to identify it is from the crystal system as there are few blue cubic minerals, so look for blue cubes.  Unfortunately, all the specimens from Arizona are micromounts with crystals from a fraction of a millimeter to a couple of millimeters in size.

It is a relatively rare mineral, found in the oxidized zones of lead - copper deposits, and found at a few localities in Arizona. The best Arizona specimens are from the Mammoth-St. Anthony Mine in Pinal County.  Other Arizona localities include the Apache Mine, Gila County, Rowley Mine, Maricopa County, and Vekol Mine, Pinal County.  The best specimens are from the type locality at Boleo, Mexico where crystals up to almost an inch have been found.

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
“EYES ON, HANDS OFF”
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.
