Abbreviations for minerals: Qz quartz, Pl plagioclase, Crs cristobalite, Py pyrite, Gp gypsum, Anh anhydrite, Alu alunite, Prl pyrophyllite, Sme smectite, Ilt illite, Kln kaolin group minerals (7A), Chl chlorite
Analyzed by Rigaku Ultima IV at Niigata University. Measurement conditions were of CuKα radiation, 40 kV and 40 mA, and scanning speed of 2° per minute. Samples were measured as bulk, oriented, and heated at 400 °C and 550 °C conditions and were also treated with ethylene glycol to identify the minerals overlapping in certain cell parameters
