Abstract
Five suture zones are described from the zone of collision between the Eurasian, Indian–Australian and Pacific–Philippine Sea plates within the eastern Indonesia region. These are the Molucca, Sorong, Sulawesi, Banda and Borneo sutures. Each of these sutures has a relatively short history compared to most pre-Neogene orogenic belts, but each preserves a record of major changes in tectonics including subduction polarity reversals, elimination of volcanic arcs, changing plate boundaries, and important extension within an overall contractional setting. Rapid tectonic changes have occurred within periods of less than 5 Ma. Many of these events, although important, would be overlooked in older orogenic belts because the age resolution required to identify them, even when the evidence is preserved, is simply not possible.
