Eastern Indonesia belongs to a convergent zone between the Asiatic, Australian and Pacific plates. A lot of synthetic papers have been devoted to this very technically active area. Our new geodynamic reconstruction takes into account a six year period of scientific cooperation between France and Indonesia. This cooperation provided various geological data. The hypothesis presented here is based on the geological evolution of lour small commentai blocks (two of which appear for the first time: the Banda und l.ucipara blocks) trapped by the convergence of the threemain plates. The main steps are successively: the Upper Eocene to Oligocene. during which the Banda block collided with the south east asiatic margin in Sulawesi: the Lower Miocene, during which the l.iicipara block (including (he Tukang IJesi platform) collided with the Banda block itself, mainly in the Buton area: the Upper Miocene, which is a period of large extensional regime. Most of the basins inside the Banda area opened at that time (North Banda Basin, South Banda Basin, Savu Basin, etc.). The next interesting period is the Upper Pliocene, which occurred after the main collisions between the Australian continental block and the Banda and Irian Java blocks. The Bangai Sula block collided with the eastern part of Sulawesi at the end of the Lower Pliocene. |
