Figure F31. Composite physical property plots of smoothed natural gamma radiation (NGR), vertical (z-direction) compressional wave velocity, bulk density, and porosity plotted against depth for Site 1276. Age, lithology, and grain size are also indicated. Lithology and sedimentary facies keys are shown at bottom. v. = very, congl. = conglomerate, clayst. = claystone, mudst. = mudstone, marlst. = marlstone, ss = sandstone, sts = siltstone.
