3 Summary of Sediment Accumulation 1. Wide range of material raining down continental dust, biological material, river-born sediments 2. Sediment thickness is high near coast due to river runoff of sediment, and high productivity that leads to high rain rate of biological material 3. Red Clays found in open-ocean: Slow rain of continental dust creates red clays 4. Calcareous or Siliceous Sediments found In high biological productivity regions: downward rain of biological material cause red clays to be flooded/diluted by biologically-derived calcareous or siliceous material
