This specimen is very rich in crystals of
coquimbite and goldichite. The crystals of
coquimbite reach up to 0.65 cm in length! Both of these species are
closely related with the primary difference being the addition of potassium in
goldichite to the chemical formula. The Dexter# 7 mine is the type and only
known locality for goldichite.
Origin: Dexter #7 Mine, San Rafael Swell, Emery County, Utah, U.S.A.
