Figure 16. Cumulative size distribution curves for typical Type II (cores 6 and 2), 

 Type IE (cores 9 and 49), and Type IV (core 46) sediment from cores 

 shown in Figure 2. Data from Rapid Sand Analyzer analysis. 

 Mean sieve value for Core 6 = 0.65 phi (0.637 mm) 

 Mean sieve value for Core 2 = 1.35 phi (0.392 mm) 

 Mean sieve value for Core 9 = 2.51 phi (0.176 mm) 

 Mean sieve value for Core 49 = 2.04 phi (0.243 mm) 

 Mean sieve value for Core 46 = 3.20 phi (0.109 mm)
