Structures in the Australian plate and the tectonics of the Banda arc

Eastern Indonesia is one of the least well-understood geological domains on Earth, yet the region is one of the few tectonic settings that is actively undergoing arc-continent collision. The NSF funded “Banda arc experiment” was designed to unravel some of the complex dynamics of convergent tectonics. This project integrated new data on neotectonic uplift rates, changes in surface topography, lithosphere-scale structural images, and the present-day thermo-chemical structure of the lithosphere and mantle beneath the Banda arc will all provide crucial insights into the history of convergence and how this varies spatially from oceanic subduction to continental collision.  The multidisciplinary experiment combined extensive field work with the deployment of 30 broadband instruments that extend across the Nusa Tenggara Timur region of Indonesia and across Timor-Leste from 2014-2018 (Miller et al., 2016).
