Metamorphic sole of the Papuan Ultramafic Belt ophiolite : field mapping, petrochemistry, geochemistry, geochronology and associated reconnaissance experimental studies on boninite genesis

Lus, Wilfred Yeherembugia

Description

The Papuan Ultramafic Belt (PUB) ophiolite comprises former oceanic crust and upper mantle that was emplaced onto continental crust in Papua New Guinea (PNG) in a zone of 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 greenschists, amphibolites, granulites, and gabbroic rocks which are separated from the overlying ophiolite by a Transition Zone of banded...[Show more]
