The sample was analyzed by electron microprobe using a Cameca SX-100 operating in wavelength-dispersive mode. The powder-diffraction pattern was recorded from a small fragment on a 114.6 mm Debye-Scherrer powder camera with a Gandolfi attachment and Ni-filtered Cu-Ka X-radiation The Fe2+-Fe3+ ratio and the H2O content were derived from the results of crystal-structure refinement. The oxo component (O2 at the O(3) site) was estimated based on the Ti content.
