Initial Reports, Volume 209 Ms 209IR-107 Chapter 7, Table T10. Piece orientations from archive half data, Site 1272. Notes: Lithology: 1 = dunite, 2 = harzburgite, 9 = basalt, 12 = gabbronorite, 16 = microgabbro, 18 = breccia. Principal component analysis (PCA) interval = level at which PCA analysis was performed. N = number of samples. Decay type: A = anchored to origin, F = free of origin, + = includes origin as point. MAD = maximum angular deviation. PCA (%) = percentage of natural remanent magnetization intensity. * = pieces labeled upside down when measured; later fixed.
