In 1943, an investigation was carried out on portions of the Latrobe Valley Brown Coalfield, using the electrical resistivity method, to see whether or not this method could prove useful in determining the depth to coal. At this time, the possibility of a gravity survey was discussed, and in January, 1948, gravity tests were commenced using a Humble-Truman gravimeter. Later, a substantial number of the readings were repeated with a more modern type of gravity meter, and a few new stations established. The results were subjected to a preliminary investigation soon after the completion of field work, but it was evident that a much more detailed study would be required before an interpretation could be completed. Prior to these tests, discussions took place between technical officers with a view to selecting an area for testing on which the results could be related to some of the known geological structures, and, subsequently, an area was selected in the Parish of Hazelwood for this purpose. The geology of the area, survey method, and results are discussed in this report. Accompanying geological plans are included.
