Figure F207. Lower hemisphere stereonet (equal area net) projections in a paleomagnetic reference frame. A. Orientations for Type 2 alteration veins observed from deeper than 50 mbsf in Hole U1309B. B. Orientations of Type 2 alteration veins observed between 50 and 80 mbsf in Hole U1309D. This subset of Figure F206 shows a clear preferred orientation, indicating more homogeneous stress in these intervals.
