TITANIT (CaTiO(SiO4)) SPHENE - TITANITE

Klaproth analysierte 1795 Material aus Passau und fand darin das von ihm entdeckte Element Titan. G. Rose führte den kristallographischen Nachweis der Identität von Titanit mit Sphen in seiner Dissertation 1820.

Klaproth had discovered the element titanium in a sample of rutile and later found it again in Titanite from Passau (Germany). In 1820, in his dissertation, G. Rose carried on further the crystallographic study of Sphene and Titanite, and realized they were the same mineral.
