Hydroxylapatite Ca5(PO4)3OH (HAP) and johnbaumite Ca5(AsO4)3OH (AsHAP) are isostructural apatite minerals naturally occurring in the oxidation zones. The main objective of this research is identification of systematic relation between structural and spectral properties and As content in the series.
