A convergent subduction model for the Solomon Islands

Abstract

Some of the data from seismic studies, gravity, and the distribution of Quaternary surfaces and deposits in the Solomon Islands are consistent with convergent subduction at the margin of the Pacific and Australian ? Solomon Sea Plates, that is, the convergent Benioff Zones meet at considerable depth and are overlain by a small wedge-shaped plate composed of lithosphere. Such convergent subduction probably occurred in the Solomons during much of Late Oligocene through Quaternary time.
