Abstract

<p>This investigation was a joint project between the Department of Geology, University of Melbourne, the Department of Earth Sciences, Monash University, and Geoscience Australia to investigate the suitability of the seismic reflection technique for determining the crustal structure within central Victoria. The project was initiated as a pilot study for a proposed 400 km deep crustal transect across Victoria in 1991-92. Funding for the project was provided jointly by the Victorian Department of Industry, Technology and Resources (ITR) and the BMR. Data acquisition was carried out during the university vacation period from the 17th to 24th June 1989 to enable participation of university staff and students. Two traverses were completed, the first 6 km long (line 89-09), and the second 8 km long (line 89-10), each being up to twelve fold common mid-point (CMP). The traverses were located on the downdip side of the Mt. Ida - McIvor fault approximately 40 km north of Heathcote. Traverse orientation was east-west and perpendicular to regional strike, and was constrained by the requirement to use existing roads and tracks in the area.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74955</b>

Lineage

A number of researchers at the three principal Melbourne universities have proposed that a geophysical transect should be carried out across Victoria to provide clear three dimensional constraints on the nature of the crust across the state (Wilson and others). The outcome of such a project should provide information on the crustal structure and genesis of the western edge of the Lachlan Fold Belt. In addition it would aid in solving two geological problems. The first is the position and nature of the suture between the westerly vergent Delamerian Fold Belt of South Australia and the east vergent Lachlan Fold Belt of Victoria. Secondly such a transect would test the mid-crustal detachment model of Central Victoria. As a precursor to an application for an Australian Research Council (ARC) grant to fund such a study, a small test survey was planned in the Stawell area of Victoria. Due to the geological complexity of the initial site the survey was moved to the Bendigo zone along the Heathcote axis.
