Triphylite

Searching for other iron (II) phosphate minerals I found triphylite. It is a lithium iron (II) phosphate mineral with the chemical formula LiFe2+PO4. It’s named in 1834 by Johann Nepomunk von Fuchs after Greek words “tria” and “phylon” which means the “family of threesome” referring to the three cations of this mineral - lithium, iron and... manganese. Triphylite occurs together with lithiophilite (lithium manganese phosphate LiMnPO4) and forms solid solutions with it. That explains the presence of manganese in triphylite. Magnesium is another element that is often found in this mineral in minor quantities. 

Weathering in the presence of water results in iron (II) oxidation to iron (III) and the formation of siderite (iron (III) carbonate) and phosphosiderite (iron (III) phosphate) among others. 

First found in Germany, Zwiesel. But also occurs in Mangualde, Portugal and Samjon village, Tajikistan.

Another mineral graftonite, an iron (II), manganese and calcium phosphate with the formula (Fe2+,Mn,Ca)3(PO4)2.

Mineral Of The Day #162: Triphylite

Mohs Hardness Scale: 4-5 Category: Phosphate mineral Formula: Li(Fe, Mn)PO4

Fun Facts:

Triphylite is used as a source of lithium and phosphorus.

It is a rather scarce phosphate mineral.

Its name in Greek means "family of three" which probably refers to the three ions: iron, lithium, and manganese.

Triphylite is the primary mineral for many beautiful and unusual secondary minerals.
