Abstract

The Australian Geological Survey Organisation (AGSO) conducted a seismic reflection survey in various localities throughout Tasmania between January and April 1995. This seismic survey formed part of AGSO project `TASGO' (b103201), a National Geoscience MappingAccord (NGMA) project carried out in conjunction with the Tasmanian Geological Survey (within Tasmania Development and Resources). The seismic survey obtained 134 km of 10 to 20 fold common mid-point (CMP) deep reflection seismic data along six traverses over an 8 week acquisition period. In addition, gravityobservations were made by the Tasmanian Geological Survey at 120 m intervals along five of the lines. Statewide aeromagnetic data has been interpolated to provide profiles along eachseismic line, and shot hole cuttings and water samples were taken for later analysis. The reflection crew provided support for AGSO's refraction and tomography data acquisition which is reported separately.

Lineage

The Australian Geological Survey Organisation (AGSO) acquired 134 km of deepseismic reflection data in parts of Tasmania in the early part of 1995. The data form a sub-set of a diverse and comprehensive data set collected by the project. In addition, coincident gravity and bottom hole samples were also acquired to assist in geological interpretation. Othercomponents of the geophysical data acquisition for this project included 1,758 line km of offshore 48 fold deep seismic data (Hill et al., 1995), a refraction and tomography experimentutilising the offshore airgun shots, and 87,000 line km of offshore aeromagnetic data.The goals of TASGO are to improve the definition of Tasmania's minerals andpetroleum potential and improve the understanding of geological controls in the distribution of these resources. The deep seismic reflection data were recorded in the mineralised DundasTrough, a gold-bearing portion of the Northeast Tasmania Terrane and the Tasmania Basin.
