内容記述 | Grain-size analysis of muddy sand or sandy mud is a matter of trouble, because the sed1- ments abundantly include both sand and clay grain size which behave differently in principle. The analysis by a single method needs a very long time and/or a large labor for one specimen. The new procedure proposed here is a combination of a settling tube method for sandy fractions and a hydrometer method for muddy fractions. The hydrometer analysis is performed according to an ordinary procedure. Then wash the sample on a 4.5-phi standard sieve. Dry the fractions rested on the sieve, and weigh it. After then, analyze the coarse fractions by a settling tube method. The settling tube method is a newly-formed system which uses an electric balance and a computer. Make the two cumulative frequency curves, and combine them by ca1- culation. Theoretically, both curves should fit at 4.0 phi of settling-size grade, on the basis of the detailed research of effects by 4.5-phi sieving, Both curves, however, often differ slightly at 4.0 phi. Therefore, they are shifted to each other at 4.0-phi grade by changing the total weight of the used sample, namely "weight correction". This procedure takes 4 days to analyze 15 samples from coarse-grained sand to clay. | |||||||||
