First recognized as "nouveau substance minérale" in 1787 by Marc August Pictet, but only described and named in 1795 by Martin Klaproth for its titanium content. A common synonym, sphene (from the Greek sphenos (σφηνώ), meaning wedge, for its common wedge-shaped crystals), was introduced in 1801 by Rene Just Haüy.
Type Locality:
ⓘTitanite occurrence, Hauzenberg, Passau District, Lower Bavaria, Bavaria, Germany
Dimorph of:
Triclinic Titanite
Isostructural with:
Durangite,Tilasite,UM1999-35-SiO:Ca
Titanite Group. The titanium analogue ofMalayaite andVanadomalayaite. It also seems to be the Ti analogue ofUM1999-35-SiO:Ca.

Forms a series withMalayaite.
Titanite close to end-member composition has space-group symmetryP21/a, whereas titanite with significant additional constituents hasA2/a symmetry.
A triclinic, Ta- and Al-bearing polymorph (above-given) has been described by Lussier et al. (2009). A synthetic titanite analogue with the formula CaAl(SiO4)F was reported by Krüger et al. (2015).

Also known assphene, this calcium titanium silicate forms flattened wedge-shaped crystals, commonly twinned with prominent re-entry angles; massive, compact and lamellar forms are also found. It occurs as an accessory mineral in igneous rocks; in schists, gneisses and other metamorphic rocks, and is also found as a detrital mineral in some sedimentary deposits.

An As- and Na-rich mineral related to titanite was just approved under the namearsenatrotitanite.
