Charles Rasp
Formula:
Pb(WO4)
System:
Monoclinic
Colour:
Pale yellow, yellowish ...

Member of:
Name:
Named after Mr. Charles Rasp (1846-1907), German-Australian prospector, and discoverer of the Broken Hill deposit.
Dimorph of:
The monoclinic dimorph of stolzite. Heating of raspite to 395(5)°C leads to a transformation into stolzite.

A rare secondary mineral occurring in the oxidized zones of tungsten-bearing hydrothermal base metal deposits.

An unusual Te-rich variety is described by Andrade et al. (2014).
