Abstract
This report covers gravity survey work conducted by Mines Administration Pty. Limited for Associated Freney Oil Fields N. L. during the period 20th June to 31st July 1959. The survey was conducted in conjunction with the seismic survey carried out by the Bureau of Mineral Resources. The purpose of the work was to define at depth the limits of the Cooroorah Anticline, Central Queensland. Gravity values were observed and plotted over the whole of the Cooroorah area, and, in particular, over the Cooroorah Anticline. These values indicate a broad gravity '''low'' south of the Mackenzie River and west of Bluff. This is confirmed by the previous regional gravity survey of 1958. Over the Big Churchyard Culmination of the Cooroorah Anticline the gravity gradient reverses. The axis of this reversal is displaced approximately 1 1/4 miles north-west from the axis of the Cooroorah Anticline. The seismic survey shows that the structure at depth is closely conformable with the surface structure so it appears from this displacement of gravity and geological axes that the gravity "high" is due to some deep-seated density variation.
