The ins and outs of a Proterozoic supercontinent - what is the significance of 990-900 Ma orogenesis for the assembly of Rodinia? The hypothesis that all of Earth's continents came together one billion years ago to form a supercontinent known as Rodinia has invigorated debate about ancient continental distributions. Current models depict a flawed configuration for Rodinia, since they assume that continental fragments preserving evidence for quite different episodes of tectonic activity between ....The ins and outs of a Proterozoic supercontinent - what is the significance of 990-900 Ma orogenesis for the assembly of Rodinia? The hypothesis that all of Earth's continents came together one billion years ago to form a supercontinent known as Rodinia has invigorated debate about ancient continental distributions. Current models depict a flawed configuration for Rodinia, since they assume that continental fragments preserving evidence for quite different episodes of tectonic activity between 1350 and 900 million years ago developed at the same time. This project will make new correlations based upon careful observation and precise isotopic dating of rocks in Antarctica and Mexico, and will use these data to develop a more realistic picture of the ancient Earth.Read moreRead less
The Early Stages of Granite Evolution: Extraction and Transport Through Ductile Crust . This research is aimed at understanding how the continents develop through several stages of rock melting. Rock melts deep in the continents to form granite magmas which rise, transporting to the upper crust important metals, such as gold, copper and tin, and heat producing elements such as uranium, thorium and potassium. This research proposal seeks to understand how granite melts form and rise transporting ....The Early Stages of Granite Evolution: Extraction and Transport Through Ductile Crust . This research is aimed at understanding how the continents develop through several stages of rock melting. Rock melts deep in the continents to form granite magmas which rise, transporting to the upper crust important metals, such as gold, copper and tin, and heat producing elements such as uranium, thorium and potassium. This research proposal seeks to understand how granite melts form and rise transporting these all important elements, which control not only our wealth but also the stability of the continents we live in.Read moreRead less
Finite Strain with large rotations: A new hybrid numerical/experimental approach. Deformation up to large strains and rotations is important in rocks, metals, polymers, and biomaterials. Computational mechanics is a standard tool for modelling such deformations. However, in earth sciences, mechanical theories use small-strain formulations or large-strain approaches with classical stress rates. Classical stress rates can lead to incorrect stored energies. This project proposes to test a new large ....Finite Strain with large rotations: A new hybrid numerical/experimental approach. Deformation up to large strains and rotations is important in rocks, metals, polymers, and biomaterials. Computational mechanics is a standard tool for modelling such deformations. However, in earth sciences, mechanical theories use small-strain formulations or large-strain approaches with classical stress rates. Classical stress rates can lead to incorrect stored energies. This project proposes to test a new large-strain theory tailored to rocks experimentally, and to apply it to a pivotal geological problem: shear zone formation. The project will advance our fundamental understanding of the mechanics and energetics of rock deformation and provide a novel tool for the modelling of large deformations.Read moreRead less
Magma dynamics and ore deposits. This project aims to advance knowledge on magma transport mechanisms through the Earth’s lithosphere, and boost predictive capacity to discover new ore deposits. Using field surveys, three-dimensional reflection seismic data, laboratory experiments and rock fracture mechanics, this project will investigate where, how and why, narrow finger-like conduits form in lithosphere-scale magma plumbing systems. The project expects to generate new knowledge on the formatio ....Magma dynamics and ore deposits. This project aims to advance knowledge on magma transport mechanisms through the Earth’s lithosphere, and boost predictive capacity to discover new ore deposits. Using field surveys, three-dimensional reflection seismic data, laboratory experiments and rock fracture mechanics, this project will investigate where, how and why, narrow finger-like conduits form in lithosphere-scale magma plumbing systems. The project expects to generate new knowledge on the formation and location of highly valuable ore deposits of nickel, copper, cobalt and platinum group elements, which are preferentially trapped in poorly understood, finger-like magma conduits. Anticipated outcomes of the project include fundamental insights into how magma transport dynamics control traps for magmatic sulfide ores as well as equipping mineral explorers in targeting their search for these important, but hard to find, ore deposits, benefitting society through future discoveries of economically strategic, new commodities.Read moreRead less
