From my observations it is clear that pyrite (iron) is attracted to fluorapatite. I’ll leave it to a geo-chemist to reveal which ions form the attraction. This unique piece has a .5cm coated fluorapatite with a pyrite stuck to the front center. The other, smaller apatites also have pyrites. . Locality: Foote Lithium Company Mine, Kings Mountain, Cleveland County, North Carolina Composition: calcium fluorophosphate and iron sulfide with Mn2 3(PO4)2·4H2O
