What is Lipscombite?
Lipscombite (Fe,Mn)(Fe)2(PO4)2(OH)2 is a green gray, olive green, or black. phosphate-based mineral containing iron, magnesium, and iron phosphate. Lipscombite is often formed at meteorite impact sites where its crystals are microscopically small, because crystal-forming conditions of pressure and temperature are brief. In the Classification of non-silicate minerals lipscombite is in the lipscombite group, which also includes zinclipscombite. This group is within the non-silicate, category 8, anhydrous phosphates, lazulite supergroup.

Chemical Properties
- Chemical Formula
- Fe2+Fe3+2(PO4)2(OH)2 Lipscombite from the type locality appears to be Mn2+>Fe2+ (but based on a pre-microprobe analysis that even its authors remark might be a bit "iffy" with regards to an accurate Fe3+/∑Fe ratio). Also, the literature describing lipscombite from other localities have not been evaluated here (yet) for any analytical data that might indicate their Mn2+/Fe2+ ratios; hence, the possibility exists that the Fe2+-dominant composition for which the mineral is officially defined may only be known from synthetic material.
