Pyroxmangite by Ron Wolf

Pyroxmangite. The mineral is manganese silicate. Sunnyside Mine. Bonita Peak. Eureka Mining District. Near Silverton, San Juan Co., Colo.

Analcime. The mineral is a hydrous sodium aluminosilicate. Normally Analcime crystals from this location are white. The unusual color of this specimen is a result of iron impurities. South Quarry. North Table Mountain. Golden, Jefferson Co., Colo.

Microcline var. Amazonite by Ron Wolf

Microcline var. Amazonite ("White Cap"). Amazonite is the blue-green variety of the feldspar Microcline. The green color of the normally white microcline is caused by the presense of lead oxide. This specimen exhibits microcline "white caps" which occur when the source of lead oxide is exhausted or disrupted during growth of the crystals. As a result, lead-free white microcline will continue to be deposited on crystal faces. 2nd Mesabi Claim. Crystal Peak District. Park Co., Colo.
