Deep seismic reflection data suggest major compressional deformation of the crust in the central Eromanga Basin area during the mid-Carboniferous

Abstract

Scismic reflection data recorded to 20 s in the central Eromanga Basin area show good quality reflections from the deep crust as well as the shallow sedimentary layers. The data along a 270 km long east-west traverse indicate warping and low-angle faulting in the lower crust which is compatible with asymmetric folding in the Devonian sediments. This interpretation is consistent with a major compressional deformation of the crust in this area during the mid-Carboniferous Kanimblan Orogeny.
