Notes: Major element oxides are reported as weight percent and trace elements as parts per million. Note that SiO2 has been subtracted from the grinding error, since pure SiO2 was used to determine grinding contamination. The background blank was determined from drift-corrected intensities and has been subtracted from standard and sample analyses. BDL = below detection limit. n = number of analyses.
