Abstract

The Bureau of Mineral Resources, Geology and Geophysics (BMR) (now Geoscience Australia), conducted the Gunnedah Basin Seismic Survey during January to April 1991. The major aim of the seismic survey was to record deep seismic reflection data across the Gunnedah Basin and bounding margins. The seismic survey would also address several problems relating to the geometry of structural units and major faults. The survey recorded 253 km of eight-fold Common-Middle-Point (CMP) seismic data. The seismic data have been processed, with the data showing good seismic reflection images of the main structural features targeted in the seismic survey.

Lineage

The acquisition of a deep reflection seismic profile across the Gunnedah Basin and bounding margins was proposed by E. Scheibner and other members of the NSW ACORP (Australian Continental Reflection Profiling) Committee. A seismic profile was seen as a major priority, to test proposed models for the structure of fault systems bounding the Gunnedah Basin and their relationship to the Gunnedah Basin (Scheibner, 1985). Several positions for seismic lines were proposed to address the objectives of testing the proposed geological models. The final seismic line position was chosen on the basis of ease of access (minimal logistic problems), avoidance of surface basalts where possible, and maintaining the targeted geological objectives of the survey. In May 1989, a short seismic test survey (Korsch & others, 1990; Wake-Dyster and Johnstone, 1993) was conducted by BMR to test whether deep seismic reflection events could be recorded over the prime objective areas of the major proposed seismic line. The results from the seismic reflection test sites indicated that shallow and deep reflection events could be recorded. Due to a higher priority of recording deep reflection seismic data in the Bowen Basin, the acquisition of a major deep seismic reflection profile across the Gunnedah Basin was delayed until 1991.
