Subject field(s)
  • Mineralogy
  • Metals Mining
  • Economic Geology
DEF

Natural calcium molybdate ..., in which a portion of the molybdenum is replaced by tungsten.

CONT

Powellite. ... The crystals are much like those of scheelite, but the latter is far commoner. The earthy material usually shows some residues of the molybdenite, which immediately suggests its identity.

OBS

Bluish-green crystals..., specific gravity 4. 35 to 4. 52. Pearly-gray scales are more common and contain only traces of tungsten. Specific gravity 4. 25.... A minor ore of molybdenum.
