Age of the metamorphic sole of the Papuan ultramafic belt ophiolite, Papua New Guinea

Lus, W.; McDougall, Ian; Davies, Hugh

The Papuan Ultramafic Belt (PUB) ophiolite is former oceanic crust and upper mantle emplaced onto continental crust in Papua New Guinea (PNG) in a zone of general convergence between the Pacific and Australian plates. The metamorphic sole beneath the ophiolite is best exposed in the Musa-Kumusi divide and comprises a 40- to 300-m-thick body of granulite and amphibolite facies rocks.
