PHARMACOLITE



Pharmacolite, a calcium arsenate hydrate mineral, occurs at Sterling Hill as minute, colorless, radiating crystals on red-fluorescent calcite, associated with picropharmacolite and calcite. Pharmacolite was verified by Dr. Eugene Foord of the U. S. Geological Survey, using X-ray and chemical analytical methods.
It is fluorescent in shortwave ultraviolet with a weak violet response color. It is not known from Franklin and is rare locally. (Dunn, 1995)
