|Mineral class||Silicates : Phyllosilicates : Mica group.|
|Habitus||Crystals as hexagonal mica books. Also as irregular mica books.|
|Cleavage||Basally perfect, producing thin flakes.|
|Color||Pale greenish, yellowish brown to brown, transparent to translucent. (Darker with increasing iron contents.)|
|Luster||Vitreous to pearly.|
|Description||A little rarer member than the other micas but not uncommon. It's been mined for it's good heat and electrical insulating properties.|
|Occurance||Common in dolomites and metamorphic limestones. Also in some pegmatites.|
|Associates||Dolomitic marbles, Hornblende, Garnets, Schorl.|
