The purpose of this report is to present the results of a number of short, reconnaissance, seismic refraction lines shot in 1961 and 1963 between the Gambier and Murray Basins and northward into the latter. One series of lines was shot in 1961 between Naracoorte and Paruna, the other in 1963, between Kingston and Meningie. In these areas, a thin (less than 2000 feet) section of Tertiary and Quaternary sediments was expected to rest on granitic or metamorphic basement. The seismic work was carried out to check for any significant variations from this expected geological picture. In 1961, B.E. Milton was in charge of operations, and in 1963 G.W. Kendall. Computations were carried out by, or under the direction of these officers.
