Abstract

In March and April 1959, a seismic party from the Bureau of Mineral Resources extended a seismic survey carried out in 1958 in the Latrobe Valley. A seismic reflection traverse was run across the Latrobe Syncline between Tyers and Traralgon South to determine the structure of the coal measures, the depth of basement and, if possible, the type of basement. Results indicated that the Latrobe Syncline (the structural feature which coincides with the Latrobe River Valley) is a broad syncline in which the strata are more or less horizontally bedded. The maximum thickness of coal measures is about 2200 ft. The survey provided information on the structures of the limbs of the Latrobe syncline and on several minor structures superimposed on the main syncline. It did not, however, show for certain what type of basement rock underlies the coal measures. The survey provided information on the structure of the formations beneath the coal measures; and although some of the seismic data is of poor quality, there is probably an unconformity in the stratigraphic section between 5000 and 9000 ft. Reflections recorded at times as great as 2700 millisec, show that the sediments in the Latrobe Valley are probably between 10,500 and 15,000 ft. deep.

Lineage

In April 1958 an experimental seismic survey was done over brown coal deposits of the Latrobe Valley by a seismic party from the Bureau of Mineral Resources. Lodwick and Moss(1959) have described the field operations and presented an interpretation of the results of that survey. Further seismic work, which is the subject of this present report, was done in March and April 1959. The survey was requested by the State Electricity Commission of Victoria to help them interpret the complex geological structure of the Latrobe Syncline. The seismic work in 1959 was an extension of the survey along Traverse B begun in 1958. In 1958 the portion of Traverse B between shot-points 22 and 28 was shot at quarter-mile intervals using the continuous profiling technique of reflection shooting. It was found, however, that much more information at the shallow depths could be obtained if shot-point intervals were reduced to one-eighth mile. In 1959 the sections of Traverse B between shot-points 28 and 51 and between 22 and 64 were shot using the continuous profiling method with shot-points one-eighth mile apart. The convention for numbering shot-points is that whole numbers refer to shot-points at quarter-mile intervals and the intermediate shot-points are denoted by half-numbers; e.g. shotpoint 34 - lies between shot-points 34 and 35. Thomas (1953) has described the geology of the Latrobe Valley, and a short outline of his work has been included in a report by Lodwick and Moss (1959). Comprehensive gravity surveys have been done in the Latrobe Valley; Neumann (1951) has presented the Bouguer anomaly maps and an interpretation of them. Two seismic surveys at Avon (Vale, 1952) and Darriman (Garrett,.1955) were done by the Bureau; the reports have been consulted as a general background to this present report.
