Mineralpedia Details for Perovskite
Perovskite
Named for Count Lev Alekseevich Perovskii, a Russian mineralogist who helped contribute to the mining industry of Russia. Perovskite is a widespread mineral with many localities including in Russia, Sweden, Switzerland, Germany, Italy, Brazil, Greenland, Canada, and the United States. It forms as “an accessory miner in alkaline mafic rocks, as nepheline syenites, kimberlites, carbonatites, [and] commonly deuteric.” It can additionally form in calcium-rich skarn and is a common accessory mineral in calcium and aluminum rich inclusions within carbonaceous chondrite.
