Stumpflite is a rare silver mineral. It crystallizes in the orthorhombic crystal system.
History
Its occurrence was first confirmed in the Driekop mine, Transvaal, South Africa.
Etymology
The mineral is named in honor of Eugen Friedrich Stumpfl (27 November 1931, Munich, Germany - 12 July 2004, Innsbruck, Austria), professor of mineralogy, Mining Institute, Leoben (Austria), for his studies of noble metal compounds.
It was discovered in 1972 by Zdeněk Johan and Paul Picot.
Physical properties
It has a silver white color. And it is metallic and isometric.
Occurrence
It is mostly found in cuprite and in low-grade copper sulfide ores in shale and carbonate rocks.
