  1. Analyzed by Rigaku RIX2000 at Fukushima University. The accelerating voltage and tube current were 50 kV and 50 mA, respectively. Data for major element and total sulfur (as SO3) content are semiquantitative by FP (fundamental parameter) method with a standard-less technique (Takase and Nagahashi 2007)
  2. *Total iron oxide as Fe2O3
  3. **Total sulfur as SO3
