Resources, Geology & Geophysics (now Australian Geological Survey Organisation (AGSO))conducted a seismic reflection, seismic crustal refraction and gravity survey in southeastern Queensland from August to November 1986. The primary objective of the survey was to complete seismic reflection coverage in the Dalby-Toowoomba area between Traverse 14 and Traverse 16 recorded during the BMR S.E. Queensland seismic survey in 1984. Secondary objectives, subject to survey progressincluded recording additional seismic reflection data east of Traverse 16 (1984) over the Beenleigh Block south of Brisbane, and a 100 km of seismic reflection data south of Mitchellover a deep crustal seismic reflection feature delinated on Traverse 14 (1984) centred at SP4030. Overall the survey objectives would allow the completion of a continuous deepcrustal seismic reflection profile of 1110 km length across southern Queensland, the basis of a lithospheric transect study in the southern region of Queensland. The survey obtained a total of 181 km of 6-16 fold CMP seismic reflection data in theBeenleigh, Darling Downs and Mitchell areas, using the Sercel SN368 seismic acquisition system. Both the primary and secondary objectives were achieved, although equipmentfailures were a major problem in causing decreased production rates. Gravity observations were made at 360m intervals along all traverses. The record presents operational information on the seismic reflection survey and preliminary sections of seismic traverses.
