  • Pyrocoproite: Mineral information, data and localities.

    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.

Pyrocoproite – It is one of the more common minerals within the samples collected in the burnt zone (Hi6b, Hi7 ed Hi8). The pyrocoproite was firstly reported by Martini (1997) in Arnhem Cave but it has never been submitted to the CNMMN: among eight samples studied by Martini (1997), only one was not completely altered in arnhemite.

  • Phosphate minerals - Wikipedia

    en.wikipedia.org/wiki/Phosphate_minerals 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.
