Pascoite
A variety of Minerals
What is Pascoite?
Crystals of pascoite, which occur in granular crusts, are minute and lath-like with oblique terminations. The mineral is dark red-orange to yellow-orange in color and dirty yellow when partially dehydrated. It occurs as efflorescences in mine tunnels or as a product leached out of surficial vanadium oxides by ground water. Pascoite has been found in association with carnotite. Pascoite melts readily to form a deep red liquid. Pascoite is a member of the eponymous pascoite group. The magnesium analogue of pascoite is magnesiopascoite.

Key Characteristics
Composition of Pascoite
A 2005 study determined that pascoite has a C 2/m disordered crystal structure. It consists of decavanadate anions (V10O28) linked together by the interstitial complex {Ca3(H2O)17}.
