Recycling of oceanic plate back into the Earth's interior at subduction zones is one of the key processes in Earth evolution. Volcanic arcs, which form above subduction zones, are the most visible manifestations of plate tectonics, the convection mechanism by which the Earth loses excess heat. They are probably also the main location where new continental crust is formed, the so-called 'subduction factory' About 400f modern subduction zones on Earth are intra-oceanic. These subduction systems are generally simpler than those at continental margins as they commonly have a shorter history of subduction and their magmas are not contaminated by ancient sialic crust. They are therefore the optimum locations for studies of mantle processes and magmatic addition to the crust in subduction zones.

Brings together a series of papers which explore various aspects of the deformation of continental lithosphere, covering different tectonic settings from the Palaeozoic to the present day. These include terrane accretion and juxtaposition, the exhumation of high-pressure terrains, and mechanisms of crustal extension and rifting.

I enjoyed reading this volume. It is rare to see such a comprehensive report on hard data published these days, especially one so insightfully contextualised by the editors' introductory and concluding chapters. These scholars and the others involved in the work really know their stuff, and it shows. The editors connect the preoccupations of Pacific archaeologists with those of their colleagues working in other island regions and on "big questions" of colonisation, migration, interaction and patterns and processes of cultural change in hitherto-uninhabited environments. These sorts of outward-looking, big-picture contextual studies are invaluable, but all too often are missing from locally- and regionally-oriented writing, very much to its detriment. In sum, the work strongly advances our understanding of the early prehistory of Fiji through its well-integrated combination of original research and the reinterpretation of existing knowledge in the context of wider theoretical and historical concerns. In doing so The Early Prehistory of Fiji makes a truly substantial contribution to Pacific and archaeological scholarship. Professor Ian Lilley, The University of Queensland
