Report on gravity survey work and drill testing completed at Leigh Creek between 1947 and 1948. Observations and results are briefly discussed.

This report discusses the proposed detonation of surplus R.A.A.F. bombs at Tadji, New Guinea. A visit was made to the bomb area in March, 1948, to observe the problems involved in detonating the bombs en masse for the purpose of a seismological study of the crustal layering of the island. Various localities in New Guinea, Papua and the neighbouring islands were visited to estimate the practicability of installing temporary seismic stations to record the detonation.

The Leigh Creek Coalfield is approximately 350 miles north of Adelaide. Coal seams of economic importance are known to occur in two basins about 5 miles apart. Immediately to the north of the known coal basins is an area of some hundred or more square miles, much of which is covered by a thin layer of rocks younger than the coal measures. Other coal basins could exist beneath this cover, and it is considered necessary to the sound development of the coalfield as a whole, that the prospecting of this area should be completed at an early date. The present survey was undertaken at the request of the South Australian Government and was carried out during October, November and December, 1947. The report is a preliminary one since the analysis of the results is not complete. However, sufficient work has been done to make possible the selection of sites for test drill holes. The geology of the area, geophysical method and application, results, interpretation, and testing are discussed in this report. The results of the gravimetric survey are shown on an accompanying plan.
