Update on geophysical survey progress from Geoscience Australia and the Geological Surveys of Western Australia, South Australia, Northern Territory, Queensland, New South Wales, Victoria and Tasmania (information current on 11 May 2018)

摘要

Further information on these surveys is available from Murray Richardson at GA via email at Murray.Richardson@ga.gov.au or telephone on (02) 6249 9229. The South East Lachlan Crustal Transect Seismic line was completed on 29 April 2018 (Figure 3). The survey is a collaboration between the Geological Survey of Victoria, Geological Survey of New South Wales, AuScope Ltd and Geoscience Australia. The $4.5 million seismic survey (631 km) was acquired by Terrex Seismic and the data will be used with other geophysical data to interpret the geological architecture of eastern Victoria and south eastern New South Wales. The objectives of the survey were to investigate resource potential and natural hazards (State infrastructure) by mapping the full crustal thickness (up to 50 km depth), aid geological interpretation across the Delamerian and the Lachlan fold belts. The line was widely acknowledged as the most difficult logistically and operationally undertaken by Geoscience Australia and the State geological surveys.
