Titanite, or sphene (from Ancient Greek σφηνώ (sphēnṓ) 'wedge'),[5] is a calcium titanium nesosilicate mineral, CaTiSiO5. Trace impurities of iron and aluminium are typically present. Also commonly present are rare earth metals including cerium and yttrium; calcium may be partly replaced by thorium.[6]
