Longshore Sediment Supply to the Deep Ocean. The current model to supply sand to deep water off continental margins is that provided by rivers operating at low sea level. We propose an alternative model in which sand is provided by longshore transport to deep water at high sea level north of Fraser Island, SE Queensland. Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entir ....Longshore Sediment Supply to the Deep Ocean.

Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entirely new exploration model for deepwater hydrocarbons, 2) provided new expertise and seabed maps for generating a superior marine naval defence capability.Read moreRead less
Biosphere, hydrocarbon and ore fluid interactions in the Early Precambrian. Ore deposits and petroleum are important for economic and social areas of Australia's growth. New discoveries are needed to maintain Australia's wealth as mines reach the end of operations and petroleum supplies decrease. This project will demonstrate how ore fluids and hydrocarbons interact in the geological environment. It should, therefore greatly expand the conceptual framework in which to explore for both mineral an ....Biosphere, hydrocarbon and ore fluid interactions in the Early Precambrian. Ore deposits and petroleum are important for economic and social areas of Australia's growth. New discoveries are needed to maintain Australia's wealth as mines reach the end of operations and petroleum supplies decrease. This project will demonstrate how ore fluids and hydrocarbons interact in the geological environment. It should, therefore greatly expand the conceptual framework in which to explore for both mineral and hydrocarbon resources, particularly in old, deep and hot basins, which are considered to be the last frontiers of exploration. Outcomes concerning the nature of early life will be of global interest.Read moreRead less
Thermo-mechanical interactive atlas of basin evolution. We propose to create a thermo-mechanical interactive atlas of basin evolution as a desktop geodynamic modelling resource for exploration geologists. The atlas will allow the user to iteratively run our 2D/3D basin modelling software ELLIPSIS to alter model parameters until they match observed basin geometries or thermal history. Model iteration will be based on interactive user evaluation of model outputs and genetic algorithms, which pr ....Thermo-mechanical interactive atlas of basin evolution. We propose to create a thermo-mechanical interactive atlas of basin evolution as a desktop geodynamic modelling resource for exploration geologists. The atlas will allow the user to iteratively run our 2D/3D basin modelling software ELLIPSIS to alter model parameters until they match observed basin geometries or thermal history. Model iteration will be based on interactive user evaluation of model outputs and genetic algorithms, which progressively modify the solution set by mimicking the evolutionary behavior of biological systems (selection, cross-over and mutation), until an acceptable result is achieved. The interactive atlas will be applied to Australian and international case studies.Read moreRead less
