Figure 2. X-ray picture from the core KS16 (3357 m water depth in the abyssal plain – 200 km from the shelf break) and detail of the hyperpycnite sequence (mean grain size, scanned thin slab, and interpretative log). The inversely graded Fd basal layer (Ha) consists of silt laminae, and begins with a gradual transition. The normally graded silty layer (Hb) begins with an erosional contact, and consists of silt layers with ripple cross laminations, multiple internal erosional surfaces, and then sub-planar laminae. The whole sequence is overlain by hemipelagic deposits (bioturbated, foraminifer-rich clay, which is lighter on X-ray picture).
