It is lithium [[manganese]](II) [[phosphate]] with formula: [[lithium|Li]][[manganese|Mn]][[phosphorus|P]][[oxygen|O]]<sub>4</sub>. It occurs in [[pegmatites]] often associated with '''triphylite''' to which it is closely related. Triphylite being virtually the same mineral except that [[iron]](II) substitutes for manganese giving it the formula Li[[iron|Fe]]PO<sub>4</sub>. Lithiophylite and triphylite form a solid solution series, a mineral with intermediate composition is known as '''sicklerite''' (Li(Mn,Fe)PO<sub>4</sub>). Lithiophylite is a resinous reddish to yellowish brown mineral crystallizing in the [[orthorhombic]] system often as slender prisms. The [[Mohs hardness]] is 4.5 and the [[specific gravity]] is 3.35. It is usually associated with [[lepidolite]], [[beryl]], [[quartz]], [[albite]], [[amblygonite]], and [[spodumene]] of pegmatitic origin. It rather readily weathers to a variety of secondary manganese phosphates and oxides. The type locality is [[ Fairfield County, Connecticut]] where it was first reported in 1878. ==External links== *[http://webmineral.com/data/Lithiophilite.shtml Webmineral] *[http://www.mindat.org/min-2418.html Mindat w/location data] *[http://mineral.galleries.com/minerals/phosphat/lithioph/lithioph.htm Mineral galleries] [[Category:Lithium minerals]] [[Category:Manganese minerals]] [[Category:Phosphate minerals]] {{mineral-stub}} {{Manganese minerals}} [[de:Triphylin]] [[it:Litiofilite]] [[nl:Lithiofiliet]] [[pt:Litiofilite]]
