Magnesiopascoite

A variety of Minerals

What is Magnesiopascoite?

Magnesiopascoite is a member of the pascoite group and is the magnesium analogue of pascoite. It is transparent and bright orange in color, occurring as intergrown, parallel stackings of crystals up to several millimeters in the largest dimension. The crystals vary from tabular to equant to prismatic. The mineral dissolves slowly in water and quickly in cold, dilute hydrochloric acid. It decomposes rapidly when mildly heated, likely as a result of dehydration.

Market Value Factors

Pricing varies for every rock and mineral, so use these universal factors to gauge Magnesiopascoite before comparing listings or appraisals.

Key Characteristics

Formation of Magnesiopascoite

In the area of the type locality, the reducing environment caused by carbonaceous material in the Salt Wash and Brushy Basin members of the Morrison Formation precipitated uranium and vanadium minerals from solution. After mining, subsequent leaching and oxidation by groundwater created magnesiopascoite. The mineral has been found in association with gypsum, martyite, montroseite, pyrite and rossite.
