An experimental seismic survey using both refraction and reflection techniques was carried out in April, 1958, near Morwell in the Latrobe Valley at the request of the State Electricity Commission of Victoria. The object of the survey was to find if the method was of value in mapping the structure of the coal measures of the Latrobe Valley and in providing information on the depth to and type of basement underlying the coal measures. Work was concentrated in an area south-west of Morwell on the southern limb of the Latrobe Syncline. The results obtained indicate that the seismic method may be applied successfully to geological problems of the Latrobe Valley and may provide useful control data for the interpretation of surface geological and gravity mapping. Various interpretations of the results are discussed and although some ambiguity exists, it might be overcome when more work is done, particularly if an accurate knowledge of the velocities of the coal easures is obtained. It has been possible by means of refraction work to map the extension of the basalt which crops out on the southern margin of the Latrobe Syncline beneath the coal measures with reasonable certainty.

<p>The Paterson Range 4-mile Sheet covers part of the south-western margin of the Canning Basin. The Sheet lies between latitudes 21 degrees and 22 degrees south, and longitudes 121 degrees 31 minutes and 123 degrees east. Its north-western corner is 195 miles on a true bearing of 102 degrees from Port Hedland on the coast. <p>The Canning Basin is defined for geological purposes as the sedimentary basin between the Kimberley and the Pilbara areas of Precambrian rocks ~ it extends north-westward on to the present continental shelf and contains Palaeozoic and younger sediments. The geographical name "Great Sandy Desert" was first used for the desert area of the Canning Basin by Colonel P. E. Warburton in 1872. <p>The Paterson Range Sheet area is uninhabited by white people and is not crossed by any road or vehicular track. Access to the area by 4-wheel drive vehicle was by way of Warrawagine Station on the adjoining Yarrie Sheet, but easier access is by way of Ragged Hills Lead Mine, which is west of the Paterson Range Sheet. The general conditions encountered and a description of the methods of investigation are given in Traves and Casey (1954, 1955 and 1956). <p>Most of the area is semi-desert and receives generally less than ten inches of rain annually; surface water is scarce and supplies can only be obtained from small springs or native soaks and rockholes which in most cases are not permanent. The area is inhabited by scattered groups of nomadic aborigines who depend for their existence on the scant fauna of lizards, snakes, kangaroos, rabbits and birds.
