About Yttrium-bearing TitaniteHide

Formula:
(Ca,Y)TiSiO5
An yttrium-bearing variety of titanite. See also keilhauite and grothite.

First named as yttrotitanite and described by Scheerer (1844) from a feldspar quarry at Buøy Island, Arendal, Aust-Agder, Norway. It was independently and simultanously described as keilhauite by Erdmann (1844).
