Times Cited Count:0 Percentile:0.02(Mineralogy)The crystal chemistry of Sr-rich piemontite from a layered manganese ore deposit of the Tone mine, Nishisonogi Peninsula, Japan, was studied using methods of electron microprobe analysis, single crystal X-ray structural refinement, Fe Mssbauer spectroscopy, and X-ray and Time-of-Flight neutron Rietveld analyses to elucidate the intracrystalline distributions of Sr, Mn and Fe and the general and individual features on the structural changes with Sr contents in piemontite and epidotes.
