Gravity observations were made at quarter-mile intervals along the road that joins Bullara and Giralia homesteads. This road crosses the northern end of the Giralia anticline normal to its axis. A seismic reflection profile, which is described in B.M.R. Record 1951 No. 62, has also been run along this road and it is possible to compare the gravity results with the seismic. Gravity station elevations were determined with an accuracy of within 0.1 of a foot and the gravity observations have been reduced to Bouguer anomalies using an elevation correction factor of 0.062 milligals per foot. The results are shown in the form of a profile on the accompanying plate. The surface profile is also plotted and the positions of some of the seismic shot points are shown alongside the gravity station numbers. These results are discussed in this report.
