Mesolite With Pyrite
Merelani Mines, Arusha, Tanzania
Small Cabinet, 6.0 x 5.5 x 1.8 cm
This unusual specimen was purchased at the Munich show from late 2011 finds, and was the only good example I saw with sharp white, acicular crystals of what was at the time, unidentified. On a hunch, I bought the piece to test it. It was analyzed at the University of Arizona and found to be mesolite. Minor diopside and graphite matrix underlays the mesolite clusters. Unusual find for the locality!
