L106 Galilee Basin seismic survey, QLD, 1975 Stacked seismic data and images for lines BMR75-A, BMR75-B, BMR75-C, BMR75-D, BMR75-E, BMR75-F, BMR75-G, BMR75-H, and BMR75-I

The Bureau of Mineral Resources made a seismic survey in the western part of the Galilee Basin in the central Queensland in 1975. The aim of the survey was to obtain basic information on the extent and thickness of the western part of the basin, which is entirely concealed beneath the Eromanga Basin. The seismic survey recorded 320 km of continuous single-coverage reflection recording and 18 km of six-fold CDP recording during 87 operating days. Two major faults were mapped. The Holberton Structure, previously known from geological mapping, corresponds to a major fault in the subsurface with up to 300 m of downthrownto the west. Another major fault appears to be a southerly continuation of the Cork Fault. For the other two Galilee Basin surveys, please see L102 and L108.
