Titanite
(Ca,REE)(Ti,Al,Fe)SiO4(O,OH,F)

     Titanite is fairly common at Mont Saint-Hilaire. It was formerly known as sphene. MSH has provided some exceptional crystals.

PHYSICAL CHARACTERISTICS:

Color ranges from lemon-yellow to pale green, greenish yellow,
   bright orange, pink and pale violet.
Luster is adamantine.
Diaphaneity is transparent to translucent.
Crystal System is monoclinic; A2/a.
Crystal Habits include superb elongated prisms to 1cm, wedge-
   shaped crystals and as embedded granular masses.
Cleavage {110} is distinct.
Fracture is uneven to subconchoidal.
Hardness is 5 - 5.5
Specific Gravity is approximately 3.5 g/cm3.
Streak is white.
Associated Minerals include aegirine, albite, amphibole group,
   analcime, ancylite, biotite, calcite, eudialyte, fluorapatite,
   gonnardite, labuntsovite, microcline, molybdenite, nepheline,
   polylithionite, pyrite, pyrrhotite and quartz.
Distinguishing Features: Crystal habit.
Origin: Named in 1795 to reflect its titanium content.
