Abstract

A seismic survey, consisting of a main north-south reflection traverse and several short supplementary reflection and refraction traverses, was made in the Gosses Bluff area, of the Amadeus Basin,Northern Territory by a seismic party of the Bureau of Mineral Resources, Geology and Geophysics between March and July 1962. The purpose of the survey was to obtain information on the lli.ssionary Plain Syncline, the Gosses Bluff uplift; the fault at the northenl flank of the Gardiner Range, and the tectonic features relative to the Archaean/sedimentary contact at the northern edge of the Missionary Plain. The seismic reflection method proved to be an excellent exploratory tool in the undisturbed parts of the sedimentary basin. The Missionary Plain Syncline was shovm. to have a maximum thickness of sediments of 33,000 ft, nine miles north of Gosses Bluff. The results indicate that Gosses Bluff is a diapiric structure of the salt dome type, where the Proterozoic Bitter Springs Limestone has provided the necessary mobile material. The Gardiner Range Fault was shown to be overthrust from the south vdth a hade of 15 to 20 degrees. The problem regarding the Archaean/sedimentary contact was not solved.

Lineage

A seismic survey was made in the Gosses Bluff area of the Amadeus Basin by the No.2 seismic party of the Bureau of Mineral Resources, Geology and Geophysics from 26th March to 3rd July 1962. The survey was part of the Bureau's programme of seismic operations in the Amadeus Basin, which began in 1961 VIi th a series of north-south traverses across the eastern part of the Basin between Alice Springs and Finke and was followed in the same year by a short survey over the Palm Valley Anticline, 80 miles west of Alice Springs. These surveys showed that relatively simple seismic reflection techniques could be used to give reliable information in the undisturbed parts of the sedimentary basin, but that only limited results could be obtained by the seismic refraction method owing to the presence of shallow high-velocity refractors in the areas tested. Many tectonic problems of the Basin were left unsolved, and it was the purpose of the 1962 surveys to try to solve some of these problems.
