GSC electron microprobe (17 oxides) (#2)
GSC Scanning electron microprobe analysis of candidate indicator mineral grains. Analysis is for 17 major and minor element oxides.
Mineral analyses were acquired on a Cameca SX-50 microprobe fitted with 4 wavelength-dispersive spectrometers, with a take-off angle of 40 degrees. The operating conditions were 20kV accelerating voltage and 10nA current, using a focused beam. Count times were 10 seconds on peak and 5 seconds off-peak. A ZAF matrix correction program of Armstrong (1988) was used to process the raw data. Reference standards used were a mixture of natural and synthetic pure metals, simple oxides and simple compounds.
A variable number of oxides were measured:
SiO2, TiO2, Al2O3, Cr2O3, V2O3, FeO, MnO, NiO, MgO, CaO, Nb2O5, ZnO, SO3, As2O3, CO2, K2O, Na2O
