Scorzalite

Scorzalite

Dr. Evaristo Pena Scorza, former Chief Mineralogist of the Mineral Survey of Brazil in Rio de Janeiro is the namesake of Scorzalite. This uncommon mineral can be found as “a secondary mineral in complex zoned granite pegmatites” and can also be found in kyanite-bearing quartzites. Scozalite has localities in Brazil, the USA including some localities in the Black Hills of South Dakota, Rwanda, Morocco, Sweden, and Germany.

Scorzalite from Champion mine, Mono Co., California, United States

Scorzalite
            from Champion mine, Mono Co., California, United States

Deep blue crystal grains throughout vuggy and brecciated matrix. Scorzalite is an important primary phosphate generally confined to pegmatites, but not always as at the Champion mine, where this specimen originates. The Champion mine is a concentrated aluminum, metamorphic environment hosting rich andalusite deposits and several other aluminum bearing minerals namely Al-phosphates and Al-silicates.
