Pottsite - Occurrence, Properties, and Distribution

Pottsite is a tetragonal-trapezohedral bright yellow mineral containing vanadium, oxygen, lead, hydrogen and bismuth. It was first discovered in 1988 from the Potts, Lander Coundy, Nevada. USA. It is named after its place of discovery.

How to Identify Pottsite

Pottsite is a bright yellow mineral having translucent appearance, light yellow streak and adamantine luster. Its fractures are brittle as shown by most of the non-metallic minerals and glasses. It can be formed as prismatic or pyramidal crystals. The density of pottsite is 7 g/cm3, and its hardness is 3.5.

Global Distribution

Pottsite is distributed in the following places:

  • Linka mine, Spencer Hot Springs district, Lander Co., about 30 km northwest of Potts, and northeast of Chalk Mountain, Clan Alpine Mountains
  • Churchill Co., Nevada, USA.

Occurrence of Pottsite and Useful Mineral Association

Pottsite occurs in the oxidation zone of a tungsten-bearing tactite. It is closely associated with vanadinite, cerussite, duhamelite, clinobisvanite, bismutite, junoite and scheelite.
