Notes: Cpx = clinopyroxene. Due to peak overlap, samples with identified lizardite may also contain chrysotile. 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 T4. This table is also available in ASCII.
