Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia White silky bundles of acicular crystals of Schaurteite with reddish-brown zinican Siderite. Field of view 7 mm—a section of a small cabinet sized example. The Schaurteite forms a seam, up to about 5 mm thick on one surface of a chunk of the Germanite/Renierite ore. The identity of Schuarteite and zincian Siderite was confirmed by microprobe ... |

Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia Bright white silky hair-like crystals of this rare Germanium Sulphate are intergrown to form a crystalline aggregate measuring 9 by 10mm. The Schaurteite is intergrown with white Calcite (probably) and is within a Germanium-rich ore probably containing Tennantite and Germanite. Size: 25mm x 30mm x 20mm |
