We have been working in East Timor since 2003, looking closely at the structural relationships and re-mapping and re-dating the formations, with a view to constraining and formulating models for the tectonic evolution of this part of Timor Island. This work involves structural mapping, igneous petrology, stratigraphy, biostratigraphy, palaeontology and anything else we can think of! To date some of our exciting discoveries include that the type section of the Miocene is in fact largely Triassic to Jurassic, the type section of the Jurassic is Triassic, we've discovered a large section of ocean floor material, complete with MORBS and cumulates, the remnants of a collided oceanic plateau, complete with OIBs, preserved as thrust stacks along strike across the island, and we've also dated the timing of collision and uplift of the island. Phew! This work is being done in close collaboration with my colleague, Assoc. Prof. David Haig, and you should check out his web pages for more information. Copies of all of our new papers should be available somewhere on this page.
2. The neo- and seismo-tectonics of the northwestern Australia
Our extensive work on the Neogene deformation history of the North West Shelf of Australia led us to contemplate the onshore effects of the tectonism we were mapping offshore. Currently, in conjunction with the ANU, we have a network of 8 seismometers buried in various locations around northern WA, recording seismicity and micro-seismicity in the region. So far we've calculated a couple of dozen fault plane solutions from events we have recorded, and are in the process of correlating these with known faults to try and identify reactivation and recent deformation. We may also try some analogue models of potential reactivated faults.
3. The Neogene tectonic history of the North West Shelf of Australia
We've been doing this for most of the last 10 years, and the project has involved mainly seismic structural interpretation of offshore seismic data. We've interpreted an awful lot of regional 2D lines, and some 3D data sets along the way. In the end we've decided that there is very little strain across the margin, even during collision, and that the response of the Australian Plate in this area is largely elastic. Strain in the Carnarvon Basin is entirely different to that in the Timor Sea. You should be able to find pdfs of our papers somewhere on this page.
4. Analogue modelling
Over the years I've done quite a bit of modelling on lithospheric-scale processes of collision, using tanks of honey and layers of putty and sand. We're planning more models on the neotectonics stuff soon.
