Left stereographic plot (lower-hemisphere, equal area) of azimuth and plunge of the P-axes (empty circles) and T-axes (filled circles); middle symmetric polar histograms showing the azimuthal distribution of the nodal planes; right stereographic plot of the normals to all nodal planes. The polar histograms (rose diagrams) show the number of nodal planes in azimuth bins of 10°
