Gems: Their Sources, Descriptions and Identification
Powellite is CaMoO4 and is isostructural with scheelite with which it forms a
series. Powellite occurs as transparent to translucent straw yellow, greenish
yellow, greenish blue or blue dipyramidal crystals of the tetragonal system; the
lustre is ...

Tungsten Mineralization in the United States
Scheelite which contains molybdenum and powellite which contains tungsten are
fairly common. The original powellite described by Melville (1891) from the
Seven Devils district in Idaho yielded 10 per cent tungsten trioxide on analysis.

The Enrichment of Ore Deposits
Powellite, CaMo04, is formed by the oxidation of deposits containing molybdenite
. At the O K mine, in the San Francisco region, Utah,8 it appears as yellow
incrustations on quartz and some of it is pseudomorphic after molybdenite.
Powellite is ...
