Geological evolution of the Indonesian Archipelago

Abstract

The Indonesian Archipelago cons ists of accretionary development of island arcs, continental blocks, rifted and drifted microcontinents, ophiolite fragments and sedimentary cover. These through a series of compli cated past to recent tectonic processes form the current configuration of the archipelago. In the geological evo lution of Southeast Asia, acti ve plate margins, resultin g in island arc development and accretionary terranes have played an important role since Late Triassic time.
