Robertson, C.S., 1963. L052 Undilla Basin seismic survey, QLD, 1961. Record  . Geoscience Australia, Canberra.

Abstract

The Undilla Basin, in north-western Queensland, is a small sedimentary basin containing Cambrian limestones which adjoin the widespread but undated CamoowJal Dolomite to the West. In the latter part of 1961 the Bureau of Mineral Resources, Geology and Geophysics did a brief reconnaissance seismic survey lasting about seven weeks in the Undilla Basin. This Record describes briefly the work done and results obtained. The occurrence of limestone near the surface throughout the basin presented difficult problems in the application of the reflection and refraction seismic methods but some progress was made towards the solution of these problems.

Lineage

From 6th October to 22nd November 1961 the Bureau of Mineral Resources, Geology and Geophysics did a reconnaissance seismic survey in the Undilla Basin, north-east of Camooweal, Queensland. The objectives of the survey were: (a) to determine the thickness of relatively unmetamorphosed strata in the Undilla Basin, (b) to determine the relation between the Middle Cambrian sediments of the basin and the undated Camooweal Dolomite to the west, and (c) to determine the existence or otherwise of a sandstone sequence between the Middle Cambrian limestone strata and metamorphic basement. It was considered that although all the necessary conditions for oil occurrence might be present in the Undilla Basin, its limited size made it unlikely that it would itself represent a large and important oil province. However, the importance of the seismic survey was believed to lie chiefly in the possibility of demonstrating the contemporaneity of the fossiliferous Middle Cambrian limestones of the Undilla Basin and the apparently unfossiliforous Camooweal Dolomite. The latter is believed to extend over a large area of north-west Queensland and the Northern Territory, although much of it is soil-covered. It was believed that the Camooweal Dolomite might be of Proterozoic Age and that it was a poor prospect for oil occurrence. However, if it could be demonstrated that the Camooweal Dolomite was deposited simultaneously with highly fossiliferous limestone of the Undilla Basin then the oil prospects of a large region would be greatly enhanced. Prior to the Bureau's 1961 seismic: survey, no Seismic work or other geophysical work had been done in the Undilla Basin although the area had been geologically mapped by the Bureau (see 1:250,000 series Geological Sheet E/54-13 9 Camooweal, 1961). Because of the widespread occurrence of limestone and dolomite it was foreseen that the area would be a difficult one for seismic work and the Bureau's Seismic Party No. 1 went prepared to spend a considerable amount of the time available for the survey doing experiments to improve the quality of results. Such experimentation was later found to be necessary.
