The proposed technique enables porosity measurement to be made on undisturbed samples taken from sand deposits. It is based on the impregnation and hardening of sand in the field and the preparation of small cube samples which are tested in the laboratory. The method proved successful in both dry and wet sand. Its application is demonstrated in the study of porosity variations in a dune. The internal structure of the dune was studied by means of replicas or peels which reveal in detail the layering of the dune sand. A definite relationship was established between porosity and relative density of the sand and its internal structure and mode of deposition. Very high densities were found in sand deposited by accretion on the dune's back. Relative densities in accretion deposits approach and even exceed 100 percent.
