Perovskite Morph

In 1839, a new mineral was discovered in the Ural Mountains and named after a Russian mineralogist with the impressive name of Count Lev Aleksevitch von Perovski. For the next 140 years, perovskite had an obscure role as a minor rock-forming mineral. It was calcium titanate, CaTiO3. Then, in the 198...

Summary:In 1839, a new mineral was discovered in the Ural Mountains and named after a Russian mineralogist with the impressive name of Count Lev Aleksevitch von Perovski. For the next 140 years, perovskite had an obscure role as a minor rock-forming mineral. It was calcium titanate, CaTiO3. Then, in the 1980s, perovskite emerged as a rock star. Perovskite had two new, and newsworthy, roles: At high pressure, magnesium silicate (MgSiO3) abandons its low-pressure pyroxene structure (#10) and dresses up in perovskite’s structure. Earth’s mantle deeper than 600 kilometers is inferred to be mostly magnesium silicate perovskite, making it the most
