Figure F30. Hole 1109D global fracture orientations. Equal area stereographic projection, lower hemisphere. Poles to frac 1 and frac 2 are shown as pink and red squares, respectively. Strike and dip histograms use 5° bins. Strike is normalized so that the dip direction is 90° clockwise from strike. Frac 1 and frac 2 histograms are stacked with same color code as stereonet poles. All these fractures are located within the bottom dolerite (Fig. F28, ) except that labeled #37 (orange), which is within the sediments at 220 mbsf (Fig. F28, ) and belongs to the frac 2 set.
