Mineral of the Month PHOSPHOPHYLLITE
Dr. Raymond Grant

Mineral of the Month for March is phosphophyllite, a zinc, iron, manganese phosphate hydrate. Color is blue-green, sea green, pale yellow, and colorless, and the hardness is 3 to 3.5. It is monoclinic and fishtail twins are common. It occurs most commonly as a secondary mineral in pegmatites as an alteration of primary phosphates. More rarely it found in hydrothermal vein deposits as an alteration of primary phosphates and sphalerite.

The best specimens of phosphophyllite come from silver mines in the Potosi region of Bolivia. The next best specimens come from pegmatites in the Hagendorf region of Germany. In the United States it has been found in pegmatites in Maine, New Hampshire, North Carolina, South Dakota, and Virginia. It has not been reported from Arizona. There are several phosphate minerals found as alteration minerals in Arizona pegmatites, but not phosphophyllite.

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.
