The volcanic Solomon Islands in the southwest Pacific Ocean are part of an intra-oceanic island arc system extending south to Vanuatu, southwest of the present-day North Fiji basin and northeast of the New Hebrides basin.
The arc lies along the northeastern side of the collision boundary of the Pacific tectonic plate and the Indo-Australian plate. The former has been subducting beneath the latter since the Cretaceous and is still active.
The islands have a mix of origins. The islands of Malaita, Ulawa, and northern Santa Isabel are volcanoes above hotspots in the mantle. The islands of Choiseul and Guadalcanal are the surface expression of a mid- oceanic ridge.
The oblique collision between the Pacific and Australian plates has resulted in the formation of complex intra- and back-arc basins. Two stages of arc growth have occurred. The first ran from the Eocene to Early Miocene, the second from the Late Miocene to the present day.
Since the Solomon Islands and their surrounding waters are comprised of young volcanic rocks and fringing reefs onshore, and oceanic crust offshore, Globalshift considers the country to have no oil and gas potential.
The volcanic Solomon Islands have no history of drilling and production. No exploration wells have ever been drilled in any of the islands or in their surrounding waters.
Globalshift does not forecast any future production of oil or gas from the country.
