Seismic velocity problems associated with Cretaceous-Tertiary carbonate sediments that overlie oil and gas fields of the North West Shelf. The major aim of this collaborative study between Partner Oil Companies and The University of Melbourne is to understand seismic velocity problems associated with tropical carbonate sediments on Australias?

The major aim of this collaborative study between Partner Oil Companies and The University of Melbourne is to understand seismic velocity problems associated with tropical carbonate sediments on Australias? North West Shelf. These problems can hinder the hydrocarbon exploration efforts below these carbonates. The project is a multi faceted study and will involve integration of seismic stratigraphy with sedimentological, micropaleontological, and geophysical data. The methods outlined below would underpin any seismic depth migration applications, thereby assisting with the delineation of new gas and oil fields, and help with the estimation of reserves in existing fields.

New tools for old rocks: first cycle provenance information. The aims of this research are to enhance stratigraphic understanding of sedimentary sequences in Western Australia through application of novel provenance fingerprinting tools in K-feldspar (Pb isotopes) & apatite (U-Pb, Sr isotopes and grain chemistry). While much stratigraphic characterization has been based on detrital zircon ages & their correlation to basement sources, two major limitations are apparent: a) zircon may be multicycl ....New tools for old rocks: first cycle provenance information. The aims of this research are to enhance stratigraphic understanding of sedimentary sequences in Western Australia through application of novel provenance fingerprinting tools in K-feldspar (Pb isotopes) & apatite (U-Pb, Sr isotopes and grain chemistry). While much stratigraphic characterization has been based on detrital zircon ages & their correlation to basement sources, two major limitations are apparent: a) zircon may be multicycle, blurring source-sink relationships, b) zircon may be absent in mafic lithologies thus biasing investigations. In this work K-feldspar & apatite provenance investigation will be undertaken on a state wide basis and include case studies in the Yilgarn Craton and Canning & Northern Carnarvon Basins.

Uncovering ancient landscapes with emerging technologies: integrating complex geospatial and fossil data to explore late Cenozoic environmental change. This project aims to use emerging technologies to unravel relationships between prehistoric climate changes and environmental impacts in northern Australia. Given current uncertainty about impacts of contemporary climate change on our biota, it is important to document the outcomes of past climatic changes and, in particular, the globally critica ....Uncovering ancient landscapes with emerging technologies: integrating complex geospatial and fossil data to explore late Cenozoic environmental change. This project aims to use emerging technologies to unravel relationships between prehistoric climate changes and environmental impacts in northern Australia. Given current uncertainty about impacts of contemporary climate change on our biota, it is important to document the outcomes of past climatic changes and, in particular, the globally critical period between 15 and five million years ago that shaped modern Australian environments. Fossil-rich deposits in the Riversleigh World Heritage Area of northern Queensland span this period. Interpretation of their fine-grained record of impact and change will improve our ability to predict and hence better manage impacts of future climate change on our unique national natural heritage.Read moreRead less
