APPENDIX B 



GRANULOMETRIC DATA AND CUMULATIVE CURVE PLOTS 



The samples in this appendix are identified by core number and sample inter- 

 val below the top of the core. Locations of the samples in each core are shown 

 in Appendix A. 



1. Rapid Sand Analyzer (RSA) . 



Data include the frequency and cumulative percent at 0.5-phi intervals. 

 Also included are median, mean, standard deviation, skewness, and kurtosis for 

 each sample. Experience has shown that grain-size values from RSA analyses are 

 consistent and slightly coarser than results of sieve analyses of identical 

 samples; therefore, empirical relations for converting RSA means and standard 

 deviation to sieve analyses equivalents have been determined. The relation- 

 ships, developed from RSA and sieve analyses at a 0.25-phi interval are (from 

 Williams, et al., 1979): 



Mean: X^sieve = 1.0735 X^^^. + 0.1876 



0RSA 



Standard deviation: O^sieve = 1.4535 0-,RSA - 0.146 

 



2. Sieve data . 



Data include frequency and cumulative percent at 0.5-phi intervals from 

 samples estimated to have gravel percentages over 10 percent. 



3. Cumulative Curves . 



Sieve data plotted at 0.5-phi Intervals. 



4. Pipet analysis . 



Percentages of sand, silt, and clay are included for each sample. 



5. Visual Accumulation Tube (VAT) . 



Percentages of sand and silt-clay as well as mean grain size are included 

 for each sample.
