Olivine and orthopyroxene crystal-fabric data for peridotites from the 139°E Ridge plotted on equal-area, lower-hemisphere projections. Contours are in multiples of uniform distribution. Half widths are 10°. One measurement per grain. In orthopyroxene CPOs comprising fewer than 100 grains, individual grains are shown as a white circle, whereas those less than 50 grains are excluded as they are too small numbers to present CPOs. N is the number of grains measured. J is the J-index. M is the M-index. pfJ is pfJ-index. a Coarse-grained texture. b Fine-grained texture. c Heterogeneous textured rocks
