Abstract
A deep crustal seismic reflection survey, conducted at Gundary Plains near Canberra, to test a digital seismic recording system, produced additional data for interpretation of seismic refraction profiles in the Lachlan Fold Best. Good reflections were recorded down to the probable Moho, at an estimated depth of 41 km. The intracrustal reflections are characterised by bands of seismic energy, which probably represent velocity transition zones within the crust.

Lineage
During April 1978 and April 1979, BMR conducted a deep crustal seismic reflection survey at Gundary Plains, 70 km northwest of Canberra. The main purpose was to test a digital seismic recording system, but the location was chosen because it lines on a long range seismic refraction profile recorded to study the curstal structure of the Lachlan Fold Belt, and is over a sequence of relatively undisturbed sedimentary rocks expected to be favourable for transmission on seismic energy.
