Banda Arc Project  Eastern Indonesia is one of the least well-understood geological domains of our planet, and yet the region provides a truly remarkable location for unraveling some of the major puzzles of plate tectonics. The recent collision of the Australian continent with the active volcanic arc in the Banda region effectively captures the initiation of continental mountain building and the cessation of island arc volcanism, offering a rare glimpse into a set of processes that have shaped Earth’s evolution over geologic time.  Since oceanic subduction and subsequent continental collision have occurred in different stages along the Banda arc, we plan to use the region to study and assess the spatio-temporal evolution of this transition using a variety of methods: seismology, geodyanmics, tectonics, low-temperature geochemistry, and geomorphology.  We have installed 30 broadband seismometers, including the first ever seismometer on Timor Leste, across the archipelago of eastern Indonesia (NTT) in 2014.   The award is co-funded by the NSF Geophysics and Tectonics Programs, and the Office of International Science and Engineering (OISE) – Global Venture Fund (GVF) and led by M.S. Miller, T.W. Becker, and A.J. West.

Congested Subduction:  ARC Discovery Project led by L. Moresi, P. Betts, J. Whittaker and M.S. Miller. The project addresses the geodynamics of congested subduction zones and their impacts on the convergent margins.  We are using a combination of 3D geodynamic modelling, plate kinematic reconstruction and geological and geophysical synthesis to determine how congested subduction zones influence plate kinematics, subduction dynamics, and tectonic evolution at orogen and global scales. We aim to deliver a transformation change in understanding the links between congested subduction, mantle flow, trench migration, crustal growth, transitions between stable convergent margin configurations, and deformation in the overriding plates of subduction zones. Determining these relationships is significant because it will provide dynamic context to interpret the geological record of ancient convergent margins, which host a large percentage of Earth's metal resources.
