Figure 7
The illustration shows a dense scatter of small points in two colors, blue and yellow, against a white background. The points form two elongated, gently curving bands that start on the left as a compact cluster and then sweep to the right while separating vertically. The blue band lies mostly above and is thicker, with many closely packed points; the yellow band lies mostly below and is slightly narrower. Near the left side the two colors are heavily mixed, while toward the right end they become more clearly separated, with each band tapering to a narrow tip.Rockbolt and surrounding region shows point clouds with similar density
