“…This seismic model can then be interpreted in conjunction with other geophysical data, such as magnetic sounding (Parkin et al, 1973;Duba and Ringwood, 1973;Olhoeft et al, 1974;Dyal et al, 1974Dyal et al, , 1975Dyal et al, , 1976Piwinskii and Duba, 1975;Vanyan and Egorov, 1977;Schwerer et al, 1974;Wiskerchen and Sonett, 1927), gravity and topographic figure analyses (Kaula, 1971(Kaula, , 1975bKaula et al, 1974;Runcorn, 1975;Bills and Ferrari, 1977;Ananda, 1977;Ferrari, 1977;Thurber and Solomon, 1978;Vermillion, 1976) and average density and moment of inertia values (Blackshear and Gapcynski, 1977;Solomon, 1974;Solomon and Toksbz, 1973;Michael and Blackshear, 1972;Gast and Guili, 1972) so that the final structural model is compatible with all information.…”
