ES Search found 5 matches:"+perovskite", most recently in a link from a post re solar energy use:
"A materials science breakthrough involving solar cells made from a material called perovskite will be introduced next year and will drive down solar cell costs and exponentially increase efficiency".
Per that Wiki thingee:
Occurrence
Found in the Earth’s mantle, perovskite’s occurrence at Khibina Massif is restricted to the under-saturated ultramafic rocks and foidolites, due to the instability in a paragenesis with feldspar. Perovskite occurs as small anhedral to subhedral crystals filling interstices between the rock-forming silicates.
Perovskite is found in contact carbonate skarns at Magnet Cove, Arkansas, in altered blocks of limestone ejected from Mount Vesuvius, in chlorite and talc schist in the Urals and Switzerland, and as an accessory mineral in alkaline and mafic igneous rocks, nepheline syenite, melilitite, kimberlites and rare carbonatites. Perovskite is a common mineral in the Ca-Al-rich inclusions found in some chondritic meteorites.
A rare earth-bearing variety, knopite, (Ca,Ce,Na)(Ti,Fe)O3) is found in alkali intrusive rocks in the Kola Peninsula and near Alnö, Sweden. A niobium-bearing variety, dysanalyte, occurs in carbonatite near Schelingen, Kaiserstuhl, Germany.
Perovskite. The new "gold".
