Chapter 9, Table T11. Piece orientations from archive-half data, Hole 1274A.

Notes: Lithology: 1 = dunite, 2 = harzburgite, 10 = gabbro, 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.
