Notes: Opx = orthopyroxene. Due to peak overlap, samples with identified lizardite may also contain chrysotile. Peaks for magnetite and chromite are indistinguishable. Qualifiers "major, minor, and trace" indicate relative abundances based on peak heights and do not necessarily reflect true relative proportions. ICP-AES = inductively coupled plasma–atomic emission spectrometry. ICP-AES data are available in Table T5. This table is also available in ASCII.
