Initial Reports, Volume 209 Ms 209IR-106 Chapter 6, Table T2. XRD results, Holes 1271A and 1271B. Notes: Cpx = clinopyroxene. * = light gray material on the margin of dark gray serpentinized harzburgite. 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.
