Abstract
<p>Geoscience Australia conducted a seismic reflection, seismic crustal refraction and gravity survey in southeastern Queenland 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 progress included recording additional seismic reflection data east of Traverse 16 (1984). Overall the survey objectives would allow the completion of a continuous deep crustal 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 six-sixteen fold Common-Middle-Point (CMP) seismic reflection data in the Beenleigh, Darling Downs and Mitchell areas, using the Sercel SN368 seismic acquisition system.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74962</b>

Lineage
The data processing of seismic reflection data from the 1984 S.E. Queensland seismic survey delineated several areas showing prominent mid-crustal reflection events. Also from the 1984 work, a data gap existed in the seismic coverage in the region of the Darling Downs between Traverses 14 and 16. Using these two factors a seismic survey was proposed to enable the data gap to be filled, and additional seismic survey work in the Beenleigh and Mitchell areas to follow-up mid-crustal reflection events recorded in those regions. The survey work also provided the opportunity to further utilise the Sercel SN368 seismic acquisition system prior to the equipment warranty expiring.
