Gammer-ray method for measuring wet bulk density of sediments is very useful for determining a thin turbidite layer. Although the value itself is not a true value, it is very useful for determining the relative change of the density. Because the density is controlled by sedimentary processes such as grain-size, specific gravity of grains, grain fabric and sedimentation rate, it recorded the physical processes of the sediment formation. Using the measurements, it is very useful to get many data for sedimentological analysis of sediments.
