    www.mindat.org/min-7260.html A pyrophospate originated from bat guano combustion in Arnhem Cave, Namibia, about 2000 years ago. Cause of combustion unknown. Originally described (together with another pyrophosphate, pyrophosphite) from Arnhem Cave, Windhoek District, Khomas Region, Namibia. See also arnhemite. Compare UM1991-10-PO:BaCaHMgSr.

  • Phosphate minerals - Wikipedia

    en.wikipedia.org/wiki/Phosphate_class_of_mineral Phosphate minerals contain the tetrahedrally coordinated phosphate (PO 4 3−) anion along sometimes with arsenate (AsO 4 3−) and vanadate (VO 4 3−) substitutions. Chlorine (Cl −), fluorine (F −), and hydroxide (OH −) anions that also fit into the crystal structure.. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common.
