2009.62.233Description
Chemical Composition: Silicates
Crystal System: Monoclinic System
Description: Common Name: Titanite
Chemistry: CaTiSiO5
Class: Silicates
Subclass: Nesosilicates
Location: Fazenda Rubin Pimenta Mine, Minas Gerais, Brazil
Description: There are two specimens. Both are green with yellowish coloring throughout.
Physical Characteristics:
•Color is green, yellow, white, brown or black.
•Luster is adamantine.
•Transparency: Crystals are transparent to translucent.
•Crystal System: Monoclinic; 2/m
•Crystal Habits include elongated wedges that form tabular or platy crystals. Some crystals are not so elongated and can have a trigonal appearance similar to a flattened rhombohedron. Twinning is common and produces a twin that is shaped like a deflatted, caved-in football, only with flatter surfaces.
•Cleavage is indistinct in two directions
•Fracture is conchoidal
•Hardness is 5 - 5.5
•Specific Gravity is 3.3 - 3.6
•Streak is white.
•Associated Minerals are chlorite, anatase, calcite, quartz, zircon and feldspars.
•Other Characteristics: Pleochroic if strongly colored.
•Notable Occurances include Gilget, Pakistan; Mt Vesuvius, Italy; Kola Penn., Russia; Ontario, Canada and New York and California, USA.
•Best Field Indicators are crystal habit, luster, hardness, twinning if present and color.
