From Synchrotron Characterisation of Single Fluid Inclusions to Archaean Geodynamics: An Integrated Study of Fluid-Rock Interaction in the Primitive Crust. In the primitive Earth, a wide range of phenomena including the initiation of biological activity and the formation of ore deposits were related to the mobilisation of mineralised fluids through the crust.

In the primitive Earth, a wide range of phenomena including the initiation of biological activity and the formation of ore deposits were related to the mobilisation of mineralised fluids through the crust. In the Archaean craton of the Pilbara (WA), we have identified, within its tectonic framework, a crustal-scale plumbing system that channelled large volumes of mineralised hydrothermal solutions. Our objective is to understand the development of this plumbing system in relation to Archaean crustal geodynamics using a combination of structural geology, metamorphic petrology, geochronology, geochemistry, and the analysis of single-fluid inclusion using synchrotron and other X-ray sources.Read moreRead less
How has the continental lithosphere evolved? Processes of assembly, growth, transformation and destruction. We will use new in-situ analytical techniques, developed In-house, to date the formation and modification of specific volumes of the subcontinental lithospheric mantle, and to define the temporal and genetic relationships between mantle events and crustal formation. Quantitative modelling will investigate the geodynamic consequences of spatial and temporal variations in lithosphere composi ....How has the continental lithosphere evolved? Processes of assembly, growth, transformation and destruction. We will use new in-situ analytical techniques, developed In-house, to date the formation and modification of specific volumes of the subcontinental lithospheric mantle, and to define the temporal and genetic relationships between mantle events and crustal formation. Quantitative modelling will investigate the geodynamic consequences of spatial and temporal variations in lithosphere composition and thermal state. Magmatic products will be used to assess the roles of mantle plumes and delamination in construction of the lithosphere and xenolith studies will investigate the evolution of oceanic plateaus. The results will provide a framework for interpreting the architecture of lithospheric terranes and their boundaries.Read moreRead less

The Ocean Drilling Program is supported by 21 countries. Australia contributes as a 1/3 member of a consortium with Canada, Chinese Taipei, Korea. The drillship JOIDES Resolution is the unique facility allowing researchers access to the environmental and geological data recorded in the seafloor.
In 2002 the JOIDES Resolution will be drilling sites of international importance in the study of the deep biosphere; deep sea gas hydrates; oceanic crust generation and evolution (utilising real time geochemical and geophysical experiments in the crust); and past ocean circulation, sea surface temperature and productivity. Fourteen Australian Universities, CSIRO and AGSO support ODP and provide scientists for pre- and post-drilling research and postgraduate training.

How has continental lithosphere evolved? Processes of assembly, growth, transformation and destruction. Novel in-situ analytical and dating techniques will be used on samples from the Earth's mantle and deep crust to define the processes by which the continents and their roots (to depths of 250 km) have been formed, modified or destroyed at different times throughout Earth's 4.6 billion year evolution. The role of oceanic plateaus and mantle plumes in building protocontinents or modifying lithos ....How has continental lithosphere evolved? Processes of assembly, growth, transformation and destruction. Novel in-situ analytical and dating techniques will be used on samples from the Earth's mantle and deep crust to define the processes by which the continents and their roots (to depths of 250 km) have been formed, modified or destroyed at different times throughout Earth's 4.6 billion year evolution. The role of oceanic plateaus and mantle plumes in building protocontinents or modifying lithospheric volumes will be evaluated. The results will provide a more robust framework for interpreting the architecture of Earth's lithosphere and will have relevance to the formation and location of resources such as Ni, PGEs, Au and diamonds.Read moreRead less

Instrumentation for combined seismic and electromagnetic Earth sounding. The set of geophysical recorders will provide the means to enhance understanding of the structure of the Australian continent in 3-D. The interpretation of multiple images of Earth structure will help to link features in the crust and mantle beneath, and provide controls on the evolution and assembly of the present continent, with a major contribution to possible geotransects as recommended in the 2003 National Strategic Pl ....Instrumentation for combined seismic and electromagnetic Earth sounding. The set of geophysical recorders will provide the means to enhance understanding of the structure of the Australian continent in 3-D. The interpretation of multiple images of Earth structure will help to link features in the crust and mantle beneath, and provide controls on the evolution and assembly of the present continent, with a major contribution to possible geotransects as recommended in the 2003 National Strategic Plan for the Geosciences. Combining seismic and electromagnetic methods will provide both geochemeical and geophysical constaints, e.g., on zones of alteration and shear with the potential for deep mineralisation.

Global Lithosphere Architecture Mapping. Compositional domains in the subcontinental lithospheric mantle reflect the processes of continental assembly and breakup through Earth's history. Their boundaries may focus the fluid movements that produce giant ore deposits.

Compositional domains in the subcontinental lithospheric mantle reflect the processes of continental assembly and breakup through Earth's history. Their boundaries may focus the fluid movements that produce giant ore deposits. Mapping these boundaries will provide fundamental insights into Earth processes and a basis for the targeting of mineral exploration. We will integrate mantle petrology, tectonic synthesis and geophysical analysis to produce the first maps of the architecture of the continental lithosphere, to depths of ca 250 km. These maps will provide a unique perspective on global dynamics and continental evolution, and on the relationships between lithosphere domains and large-scale mineralisation.Read moreRead less

2003 is the final year of the Program. The ship, during this historic year, will be drilling sites of international importance in the study of oceanic crust generation; past extreme climates linked to mass extinctions; past ocean chemistry and circulation; and the formation of continental margins. Fourteen Australian Universities, CSIRO and AGSO support ODP and provide scientists for pre- and post-drilling research and postgraduate training.
