Hole 1131A: FMS image showing a firmground (bright coloured) at the boundary between Subunits 2A and 2B. High levels of (uranium) gamma-ray are associated with the firmground and the overlying 3 metre interval. The concentration of uranium in the interval immediately overlying the firmground may represent a condensed section recording slow sedimentation.
