Figure 208. Curves showing rates of accumulation of the various components of basin, continental slope, and deep- 

 sea floor sediments. The same grouping of basins is used here as in Figure 203. Note the similarities and diff"erences 

 between curves for absolute rate of deposition and for the percentage compositions given in Figure 203. Values for 

 organic matter are at surface of sediment.
