L095 Braidwood Tidbinbilla deep crustal seismic reflection survey (Murrumbidgee Batholith Basin), ACT, NSW, 1969 Stacked seismic data and images for line BMR69-BA

An experimental seismic reflection survey was made at Tidbinbilla, ACT and Braidwood, NSW in 1969 to investigate the use of long spreads and common-depth-point profiling techniques for recording deep crustal reflections. The survey was complementary to an experimental seismic survey at Mildura, Victoria and Broken Hill, NSW in 1968 to develop techniques for recording deep crustal reflections preparatory to a seismic reflection survey on the 'Geotraverse', a line across the Precambrian shield in the southern part of Western Australia, along which the Australian Upper Mantel Committee initiated a project to study the Earth's crust and upper mantle.
