Project Title:
Computational Schemes in Nonlinear Solid Geodynamics

The solid geophysical flow of constituent planetary processes occurring at multiple spatial and temporal scales exhibit nonlinear viscoplastic-elastic effects. For this reason, the incorporation of these non-Newtonian effects into a single constitutive relationship allows, in principle, the modeling of phenomena such as faulting, shearing, magmatic flow, subduction, convection and even plate tectonics in a unified manner (Mühlhaus and Regenauer-Lieb, 2005). Through this unified model, the different components of mechanical flow incorporating Newtonian, power-law, plastic and elastic flow components are represented as coincident features of a single physical model. In this regard, we consider the steady (Boussinesq) Stokes equations as applied to solid state geophysics which are given in terms of velocity and pressure by:

in conjunction with the incompressibility constraint:

These equations are completed with an initial condition for the velocity:

and a "no flow" boundary condition:

The coincident features of this model are then determined by way of the composite deformation rate given as follows under the Maxwell constitutive model:

In the case of solid geophysical convection, the mechanical flow components are then controlled by the strong exponential temperature and pressure dependence of the composite viscosity.
A significant computational difficulty arises from the solution of these equations in this context. In particular, the difficulty is associated with:
" the incompressible treatment
" the strong nonlinearity and contrast of the viscosity
This project seeks to address these difficulties and develop an improved high-level solution framework and computational solution schemes that can be applied to transient nonlinear solid state geodynamics flows.

Project Title:
Flue Gas and CO₂ Geosequestration in Surat and Bowen Basin Coals

The most feasible way for Australia to significantly reduce emissions, given current technological and economical restraints, is to sequester emissions from large point sources (e.g. power stations) underground. Deep un-minable coal seams are an abundant geological medium, close to emission point sources, in both Queensland and New South Wales that could potentially store the bulk of these States’ carbon emissions. Sequestration in coal has additional environmental and economical benefits in that the sequestered carbon dioxide (CO₂) will displace natural gas. This natural gas could be sold to offset the cost of sequestration, and burning natural gas produces ~50% less carbon emissions than coal for a given amount of energy. Our project will investigate the geochemical reactions that occur at depth between coal and a range of fluids, from flue gas (nitrogen + water + CO₂ and others) to pure CO₂. If injection of flue gas is found to be a more efficient means of sequestration than injection of pure CO₂, this will eliminate the need to isolate CO₂ from bulk power station emissions (flue gas) and thus significantly lower the cost of sequestration.

Project Title:
4D picture of mantle heterogeneity in subduction zones: a geochemical and geochronological study of submarine volcanoes and spreading centres, Vanuatu.

Subduction zones are sites of recycling of oceanic lithosphere, chemical modification of the upper mantle, magma production and crustal growth. One approach to the study of these dynamic systems has been through geochemical examination of arc volcanoes. Although the compositions of arc magmas have provided important first-order insights into subduction zone processes, a more detailed understanding is hampered by a scarcity of undifferentiated magmas derived directly from subduction-modified mantle wedge. This project will investigate how subduction and backarc spreading influence the time-dependent composition and flow patterns of the upper mantle so as to provide new insights into the structure and composition of the mantle wedge and the processes that modify the composition of mantle through time.

Project Title:
Geological controls on gas flow pathways in coal seams.

The aim of the study is gain a better understanding of natural and induced changes in reservoir pressure, water and gas migration in coal seam reservoirs over time during production at the field scale. Production across the chosen gas field of study has varied considerably, both within and between reservoir seams due to drilling performance and geology. Understanding this variability in past reservoir behaviour, in particular the role of geology and coal seam character leads to better modelling and prediction of future reservoir behaviour.
If reservoir behaviour during commercial gas extraction can be understood, then better scale-up models for injection, enhanced residual gas recovery and potential sequestration of CO₂ can be developed.

Project Title:
Human impact on estuarine environments - an example from Moreton Bay, southeast Queensland

The project will provide new knowledge towards understanding of the geological history of Moreton Bay. Moreton Bay is one of Australia's largest estuarine systems and could be a good model to understand links between terrestrial and marine ecosystems since European colonization. The currently available evidence suggests Moreton Bay has been drastically changed since European arrival, with accelerated rates of sedimentation and delivery of carbon and nutrients from the terrestrial to the marine environment.

By taking cores and using stratigraphic techniques and stable isotope analysis I will be able to investigate the history and the extent of spatial variation in deposition of terrestrial material across different sites in the bay as mangroves, salt marsh and supra-tidal salt flats. Sedimentological analysis (Total Carbon (TC), Total Organic Carbon (TOC), grain size, mineralogical composition, trace metal concentration, and Pb isotopes) of sediment cores will define variations in type and in the rate of sediment supplied to the Bay as a function of time. This set of data will provide information on the paleo-environmental evolution of the Moreton Bay area, with emphasis on anthropogenic input during the last 200 years.

Project Title:
Palynology of Upper Jurassic-Lower Cretaceous strata, coastal basins, Tanzania

In recent years the application of biostratigraphy to hydrocarbon exploration has become increasingly important both scientifically and economically. This has triggered interest in biostratigraphic research in Tanzania, particularly in the coastal basins which are being actively explored for hydrocarbons. In this context, the objectives of my project are to provide detailed palyno-chronostratigraphy, biozones, and palaeoenvironmental synthesis of Upper Jurassic-Lower Cretaceous succession of the hydrocarbon-prospective Tanzanian coastal basins. Results of this study should greatly enhance future exploration in the basins and significantly reduce the financial risks in hydrocarbon exploration. In a broader context, my research aims to enhance biostratigraphic (particularly palynostratigraphy) calibration of Late Jurassic through Early Cretaceous time interval in the Western Gondwana region.

Project Title:
Historical (Holocene) and modern foraminiferal assemblages of Moreton Bay: Temporal, spatial distributions, natural vs. anthropogenic influences and implications for coral communities

I'm interested in foraminiferal studies of Moreton Bay. Since European colonisation over the past 200 years, coastal areas have undergone deterioration and the coral communities in the Bay have undergone significant faunal changes overtime. The nature and timing of these faunal changes is uncertain and essential in furthering our understanding of why these faunal transitions occurred and what the significance of natural (long-term) versus anthropogenic (short-term) influences are on regional coral communities. Living, sub-modern (since European colonization) and fossil (Holocene) foramininferal assemblages can will be studied to provide clues to the questions of when, how and why historical faunal changes occurred and a clearer picture of what the pre-impact environmental conditions were like in the Bay.

Project Title:
Thermochronology, landscape evolution and denudational history of the Borborema Province, northeastern Brazil

I propose to study the geomorphological evolution of the Borborema Province in northeastern Brazil to unravel the uplift, weathering, and erosional histories of the shield that provided the sediments now stored in the marginal sedimentary basins. To achieve these objectives, I will combine ⁴⁰Ar/³⁹Ar, apatite fission track, (U-Th)/He, and ⁴He/³He thermochronology to derive a thermal history for the Borborema Province spanning from the Late Proterozoic to the Present; in addition, the application of cosmogenic isotope analysis will provide information about present erosional rates in the area. The dynamic information derived from the thermal history and modern erosion rates will be integrated and modeled to infer uplift and erosion rates in the past. This approach will permit quantifying the amount of sediment derived from each area of the Borborema Province; it will provide information on the most significant sediment sources, and it will permit carrying out mass balance calculations to compare, in discrete time steps, the volume of eroded crust with the mass of sediments currently stored in the marginal basins.

Project Title:
Climatic and environmental reconstruction based on reef corals from the Vietnamese coast of the South China Sea

Globally climatic and environmental changes have been a controversial issue in recent years, especially following the recognition that eustatic sea level rise due to global warming can damage human beings. The interpretations of future climatic variability and environmental change require long-term records of climatic and environmental data. It is challenging to obtain such data because instrumental records only offer relatively recent data, typically less than 100 years from present. Fortunately, the landmark discovery of climatic and environmental-dependent proxy archives such as lake and ocean sediments, wind-blown deposits, ice cores, tree rings, speleothems (caves) and corals, and the recent breakthrough of very precise analytical techniques have helped scientists to rebuild the climatic variation and environmental change in a long timescale (back to hundreds of thousand years). This PhD project was proposed to reconstruct the variability of climate and environment back to the Holocene (10,000 years BP) based on dead corals on different sea level stands, and live corals collected along the Vietnamese coast of the South China Sea. The objectives of the project are to:

   1. reconstruct the fluctuations of sea levels at millennial to multi-decadal scales and the history of coral reef development since Early Holocene (post-glaciation) by using the TIMS U-series and radiocarbon dating techniques
   2. unlock the windows to sea surface temperature and sea surface salinity archives since the Early Holocene by using δ¹⁸O, Sr/Ca, Mn/Ca, U/Ca.
   3. define the timing of recent coral bleaching and high-death events. Water quality during death events is reflected by characteristic trace element concentrations, and Sr/Ca, Ma/Ca, U/Ca, Ba/Ca values, and rare earth elements patterns

This project is right on the cutting-edge of global climate change research and will be significant nationally and internationally to understand the natural environmental changes of our planet on long timescales, which can offer the context for understanding today's climate dynamics; anticipating how the planet might respond to future environmental perturbations; and for elucidating the impacts of natural versus anthropogenic influences.

Project Title:
Radiometric Dating and Geochemical Tracing of Paleo-Seismic Events in the Eastern Mediterranean (Turkey & Israel)

The North Anatolian and the Dead Sea Fault Systems in Turkey and Israel are some of the most seismically active regions in the world. This active continental plate boundary is responsible for major earthquakes documented by historical and archaeological records. However, direct information on the timing of prehistoric earthquakes and fault initiation is limited and highly controversial. In this project we are using novel radiometric techniques to determine the precise timing of near-surface fault movements. This will allow us to obtain robust constraints on the timing of prehistoric earthquakes and the timing of fault movement initiation. Our radiometric dating approach incorporates ³⁹Ar-⁴⁰Ar, K-Ar and Rb-Sr analyses of syn-tectonic authigenic clays, as well as U-series analyses of carbonate deposits in co-seismic fissures.
