* = only in Site U1352 samples, † = only in Site U1351 samples. Full pattern degree of fit: average = 0.097, standard deviation = 0.011, minimum = 0.071, maximum = 0.200. Statistics apply to all samples analyzed from four sites. Full pattern degree of fit parameter between the calculated and measured pattern for all samples are included, and values <0.1 are preferable (Eberl, 2003). Abbreviations of minerals used in the report are noted.
