Early in 1949, an extensive gravity survey was carried out between Sale and Orbost by R.H. Ray Co., U.S.A. for Lakes Oil Ltd. (Ray, 1949). The results of this survey were assessed by Professors Hills (1950) and Rudd (1950), Geological Consultants to Lakes Oil Ltd. As a result of their recommendations, supported by the Victorian Geological Survey, the Bureau of Mineral Resources was requested to carry out further geophysical work in the area. The work carried out by the Bureau includes gravity, seismic, and aeromagnetic surveys. In this record it is proposed to discuss the interpretation of the gravity results. As the Bureau's gravity work is complementary to the Ray Co. survey, the results of both surveys have been combined. The gravity work carried out by the Bureau was intended to provide more detail in some areas not fully covered by the Ray Co. survey, and to extend the margins of the survey on to the basement at the north, and along the coast on the south-east side. Most of the Bureau's work was in areas of difficult access, in swampy or sandy country. The following areas were covered. (1)The coastal area, between Lake Reeve and the sea. (2) Along the shore of Lake Wellington and adjacent areas. (3) To the south-west of Lake Wellington, to define the end of the Baragwanath anticline more closely. (4) In several areas west of Bairnsdale and north of Holland's Landing, to provide more detail on anomalies revealed by the Ray Co. survey. (5) To provide more detail on an anomaly near Giffard in the south-western part of the area. (6) Along several traverses northwards into the highlands.
