Part 4. Plate boundary evolution in the Solomons region: Crustal variations in the Solomon?Papua?New Guinea region based on seismic investigations

Abstract

Explosion seismic investigations provide the definition required to enable the variations in gross crustal structure over quite small areas to be outlined. Typifying the crustal structure in any particular area may however be misleading. A number of seismic surveys have now been conducted which outline the variations in crustal structure between the Barkley Tablelands of northern Australia and the Ontong Java Plateau of the western Pacific. These surveys involved a number of different shooting/recording configurations; land shooting and recording, marine shooting/land recording and marine shooting and recording.
