Initial Reports, Volume 209
Ms 209IR-103
Chapter 3, Table T2. XRD results, Hole 1268A.

Notes: Due to peak overlap, samples with identified lizardite may also contain chrysotile. Sample 209-1268A-21R-2, 21-24 cm: poor quality, high noise, low count rates. 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.
