Figure F34. Anisotropy of low-field magnetic susceptibility (AMS) data from discrete samples from Hole 1256D (from top of Gabbro 1 downward). A. Data in the azimuthally unoriented IODP core reference frame, showing a random distribution. B. Data after restoration of ChRM declinations to a common north, resulting in a coherent fabric. C. Samples with prolate AMS fabrics, which have a pronounced north–south orientation of maximum principal axes (magnetic lineation).
