LATE PALAEOZOIC PALAEOGEOGRAPHY OF CENTRAL ASIA: A PALAEOBIOGEOGRAPHICAL APPROACH USING IMPROVED BIOSTRATIGRAPHY. Fossil data from Central Asia (Afghanistan, Uzbekistan, Pakistan, NW China, Mongolia, Altaids) indicate significant degree of palaeo-latitudinal variation in biogeographical patterns across the Palaeo-Tethys and its flanking shelves during Late Palaeozoic, but details of these patterns and implications for enhancing contemporaneous palaeogeographical models are virtually unknown. Thi ....LATE PALAEOZOIC PALAEOGEOGRAPHY OF CENTRAL ASIA: A PALAEOBIOGEOGRAPHICAL APPROACH USING IMPROVED BIOSTRATIGRAPHY. Fossil data from Central Asia (Afghanistan, Uzbekistan, Pakistan, NW China, Mongolia, Altaids) indicate significant degree of palaeo-latitudinal variation in biogeographical patterns across the Palaeo-Tethys and its flanking shelves during Late Palaeozoic, but details of these patterns and implications for enhancing contemporaneous palaeogeographical models are virtually unknown. This project will analyse the biogeographical patterns of Late Palaeozoic brachiopod, coral, fusulinid faunas using advanced statistical methods, and integrate biogeographical signals with palaeomagnetic data to constrain models for the Late Palaeozoic geological evolution of Central Asia-a vast region that is known to bear enormous potential for natural resources but remains geologically little explored.Read moreRead less
Time frame for the evolution of Australia's extraordinary mammals. This Project will refine a national biostratigraphic framework integrating growing understanding about the history of Australia's unique mammals, climate change and geological events. Increasing precision in correlating Australia's phylogenetic, palaeoecological and palaeoclimatological events will clarify how these act synergistically to change environments and biodiversity. Increased precision in the biostratigraphic framework ....Time frame for the evolution of Australia's extraordinary mammals. This Project will refine a national biostratigraphic framework integrating growing understanding about the history of Australia's unique mammals, climate change and geological events. Increasing precision in correlating Australia's phylogenetic, palaeoecological and palaeoclimatological events will clarify how these act synergistically to change environments and biodiversity. Increased precision in the biostratigraphic framework will also serve evolutionary genetics which needs age data to calculate molecular rates of divergence, economic geologists needing to know the age of Cainozoic sediments, biologists trying to understand the origins and nature of biodiversity and conservationists using divergence dates and relative branch lengths to help determine conservation priorities.

Trace element geochemistry of microbialites: towards an independent record of biogenicity, microbial communities, and seawater chemistry. A vast amount of Australia's mineral wealth is held in rocks of Precambrian age, yet those rocks are notoriously difficult to date and correlate owing to the rarity of fossils. Successful discrimination of different microbialites using biochemically sensitive trace elements will provide a firm basis and rationale for stromatolite biostratigraphy and greatly in ....Trace element geochemistry of microbialites: towards an independent record of biogenicity, microbial communities, and seawater chemistry. A vast amount of Australia's mineral wealth is held in rocks of Precambrian age, yet those rocks are notoriously difficult to date and correlate owing to the rarity of fossils. Successful discrimination of different microbialites using biochemically sensitive trace elements will provide a firm basis and rationale for stromatolite biostratigraphy and greatly increase our ability to understand the geological evolution and distribution of Precambrian rocks and resources. Additionally, a better understanding of the information content of stromatolites will yield considerable insight into the origin of life on Earth and its relationship to Earth's evolving chemistry and environment.

Unlocking archives of faunal dispersal and extinction: the key to reconstructing palaeoenvironmental change in Southeast Asia. The influence of environmental change on faunal populations is a pressing issue for Australian communities in environmentally sensitive areas. This will be addressed by documenting how fauna (and humans) in Southeast Asia, our nearest neighbours, responded to environmental challenges. Revealing when humans dispersed through the region and how they adapted will contribute ....Unlocking archives of faunal dispersal and extinction: the key to reconstructing palaeoenvironmental change in Southeast Asia. The influence of environmental change on faunal populations is a pressing issue for Australian communities in environmentally sensitive areas. This will be addressed by documenting how fauna (and humans) in Southeast Asia, our nearest neighbours, responded to environmental challenges. Revealing when humans dispersed through the region and how they adapted will contribute to our understanding of the cultural heritage of Australia's indigenous settlers. This project will develop established Indonesian collaborations, encourage new collaborations with Chinese, Thai, English and Dutch researchers to promote Australian research on a world stage, and pioneer new dating methodologies to enhance Australia's place at the forefront of geochronology.Read moreRead less
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.
