Notes: Lithology: 1 = dunite, 2 = harzburgite, 10 = gabbro, 14 = troctolite, 17 = serpentinite. N = number of samples. Decay type: A = anchored to origin, F = free of origin. MAD = maximum angular deviation. PCA (%) = percentage of natural remanent magnetization intensity. * = PCA (%) normalized to 15-mT demagnetization step. † = sample marked upside down. Corrected direction = 231/28.7. This table is also available in ASCII.
