Abstract

Between February and April 1961 the Bureau of Mineral Resources, Geology and Geophysics made a seismic survey in the Rosedale area of the Latrobe Valley, partly at the request of the State Electricity Commission of Victoria to provide more information about the brown coal measures in this area, and partly in order to test the Bureau's latest seismic recording equipment. One traverse, combining both reflection and refraction profiling techniques, was run south from the A.P.M. No.1 bore at Rosedale as far as Merrimans Creek, and a second traverse was run west from the bore as far as Toongabbie. Results show that the maximum thickness of the Tertiary sequence is about 3000 ft and that it thins gradually to 1000 ft at Toongabbie and rapidly to about 750 ft on the Baragwanath Anticline. It is shown that early Tertiary deposits were laid over the whole area but have been uplifted and partly eroded in late Tertiary or post-Tertiary times in the Toongabbie and Baragwanath areas, but the main syncline sank and accumulated thick Tertiary sediments. Results show alao that on the northern flank of the Baragwanath Anticline where crossed by the seismic lines the Tertiary and Jurassic sediments are steeply folded but not necessarily faulted. No positive information was obtained below 4500 ft but long refraction shots suggest that a high-velocity basement does not exist at a depth less than 12,000 ft.

Lineage

Between 22nd February and 13th April 1961 9 the Bureau of Mineral Resourcest Geology and Geophysics made a seismic survey in the Rosedale area of the Latrobe Valley, Victoria. The survey consisted of two traverses as shown on Plate 3, involving both reflection and refraction techniques. Both traverses were linked to the A.P.M. No.1 bore at Rosedale. The survey had been planned to serve two purposes; firstly, the State Electricity Commission of Victoria had requested that some seismic work be done in this area to improve knowledge of the brown coal deposits, and secondly, the Bureau had acquired a new set of seismic recording equipment and it was necessary to test it thoroughly under field conditions close to headquarters before committing it for major survey work in the Northern Territory.
