Occunnrnce: Found as a replacement of wood and as a cement in sandstone
at the Jo Dandy and other mines, Paradox Valley, Montrose Co., Colorado.
Associated with gypsum, pyrite, ty'uymunite, limonite and sometimes paspoite'
DtscussroN: Apparently new but its nature does not permit the accurate
determination of its composition or properties. Apparently differs from alaite in
the amount oI water, stage of oxidation of some of its vanadium and some of its
physical properties. The name is an unfortunate choice since the mineral is prob'
ably not an oxide of vanadium but a vanadyl vanadate.

I know, although the mine is an old one. This sample was found by parties who were

that only a small amount of this ore was found. The Colorado localities given in
Dana's Mineralogy for this mineral are: The Yankee Girl Mine, Ouray County,
and The Black Prince Mine. Summit Countv. These.localities are old and the
mines closed.
This sample is massive and apparently perfectly homogeneous, but it contains
a considerableamount of zinc and lead. No zinc blende or qalena could be detected'
