* Notes: All analyses done on a Cameca SX-50 wavelength dispersive microprobe operating at 15 keV accelerating voltage, 10-15 mm beam diameter, and 6 nA beam current. Standardization achieved by use of mineral and glass standards. Analyses recast to 100% on a water-free basis. (#), standard deviation; n, number of analyses; FeOt, total iron oxide as FeO; H2Od, water by difference. Sulphur Creek is the average of samples UT540, UT1056, and UT1614. *
