Scholzite

Named to honor Dr. Adolph Scholz, a German chemist and mineral collector. Occasionally a primary mineral, but usually a secondary mineral in zinc phosphate-bearing granites and sediments. Found at just a few localities including Germany, the Czech Republic, Italy, Belgium, Zambia, Australia, China, and the United States including here in the Black Hills of South Dakota at the Tip Top mine.
