Abstract: As-bearing phosphosiderite (3−9 wt % As2O5) from Atacama, Chile, was studied by X-ray powder diffraction, thermal and microprobe analysis, and by infrared, Raman, and Mössbauer spectroscopy. The averaged formula of the studied phosphosiderite, normalized to two cations, is ( Al0.04)[(P0.94As0.06)O4].2.02H2O. The parameters of the monoclinic unit cell of As-bearing phosphosiderite were determined by X-ray powder diffraction: a = 5.3258(6) Å, b = 9.8003(11) Å, c = 8.7116(9) Å, and β = 90.64(1)°. The As → P isomorphic substitution was established in the tetrahedral position of the mineral. [ABSTRACT FROM AUTHOR]
