Figure F13. Close-up images of items of lithologic interest, Hole U1404A. A. Diagenetic sulfide halo after bioturbation or organic matter in middle Eocene claystone. B. Fish tooth with borings from middle Eocene claystone. C. Clast of poorly consolidated, poorly sorted, very fine quartz silty sandstone (possible ice-rafted debris). D. Lithic grain debris of very poorly consolidated, poorly sorted, very fine quartz silty sandstone from the late Eocene. Smaller clasts are typical of the style and size of most sand-sized lithic grains that are visible in split cores.
