Figure F15. Core photographs and corresponding CT images of heterogeneously fractured or brecciated intervals in the upper part of the fractured/brecciated zone. A. Intervals 316-C0006E-39X-1 and 39X-2. B. Close-up of breccia (interval 316-C0006E-39X-1, 24–43 cm). On the CT image (right side), intervals appearing as nonfractured correspond to drilling mud and fragments injected between more coherent pieces during drilling (biscuiting).
