Ancient sedimentary phosphorite is the major source of commercial phosphate in Australia and East Asia. This project will lead to economic and environmental benefits to Australia by providing the minerals industry with the tools to target purer phosphate, thus improving resource estimations and minimising the environmental impact of trace metal burdened fertiliser. The study will enhance our understanding of the nature and timing of key moments in Earth history and could serve as a launchpad for future studies on the use of phosphate for environmental remediation. We hope to provide exciting opportunities for Australian postgraduates through cutting edge research in partnership with both homespun and international academic collaborators.Read moreRead less

Summary
Linking continental emergence and climatic evolution on the Early Earth. This project will use a range of innovative geochemical techniques to constrain the timing and extent to which the continents were emergent (above sea-level) throughout Earth’s history and its impact on climatic evolution. Continental emergence was pivotal to the development of our habitable planet, as it controlled the influx of bioessential elements, like phosphorus, to the oceans. Expected outcomes include a detailed rec ....Linking continental emergence and climatic evolution on the Early Earth. This project will use a range of innovative geochemical techniques to constrain the timing and extent to which the continents were emergent (above sea-level) throughout Earth’s history and its impact on climatic evolution. Continental emergence was pivotal to the development of our habitable planet, as it controlled the influx of bioessential elements, like phosphorus, to the oceans. Expected outcomes include a detailed record of changes in ocean chemistry, and a time integrated model for the emergence of continents on the early Earth. Documenting the impact of changes in the solid Earth on evolution is not only of interest to society in general, but also contributes to understanding the formation of Australia’s vast iron ore deposits.Read moreRead less
Crustal-Scale Fluid Flow in Deep Intracontinental Settings: Conditions, Sources and Deformational Responses. Fluids are important agents of heat and mass transport in the Earth's crust. They play a key role in the mobilisation of metals and as such play a crucial role in the generation of ore deposits. The outcomes of this project will result in a greater understanding of the mechanisms and sources of fluid generation and mobilisation in deep-crustal settings. These outcomes can be related direc ....Crustal-Scale Fluid Flow in Deep Intracontinental Settings: Conditions, Sources and Deformational Responses. Fluids are important agents of heat and mass transport in the Earth's crust. They play a key role in the mobilisation of metals and as such play a crucial role in the generation of ore deposits. The outcomes of this project will result in a greater understanding of the mechanisms and sources of fluid generation and mobilisation in deep-crustal settings. These outcomes can be related directly to the understanding of the controls on the transport and deposition of metals and hence the formation of mineral resources which are vital to maintaining a strong Australian economy.Read moreRead less
Hidden geochemical treasure: apatite inclusions in zircon. This project aims to undertake high precision measurements of the isotopic composition of tiny apatite inclusions in the mineral zircon. This project will create a new isotopic data set to combine with age and isotope data for the host zircons in order to study the formation and evolution of the Earth's crust. Primary apatite inclusions represent a previously untapped treasury of pristine geochemical information made accessible by the la ....Hidden geochemical treasure: apatite inclusions in zircon. This project aims to undertake high precision measurements of the isotopic composition of tiny apatite inclusions in the mineral zircon. This project will create a new isotopic data set to combine with age and isotope data for the host zircons in order to study the formation and evolution of the Earth's crust. Primary apatite inclusions represent a previously untapped treasury of pristine geochemical information made accessible by the latest advances in micro-analytical and imaging technology. This information will be used to test models for the timing of formation of the first continents, to map continental growth over time, and to evaluate the origins of the Earth's oldest rocks and minerals and the environmental conditions on the early Earth.Read moreRead less
Biogeochemical characterisation of Archaean microfossils, biomarkers and organic matter: Probing the nature and diversity of early life on Earth. Recognizing biological signatures in ancient rocks poses the single greatest challenge to our understanding of the origin and evolution of life. This Project will use new advanced technology to reveal when and where life first appeared and assess its impact on the environment, atmosphere and climate. Results are essential for understanding the transfor ....Biogeochemical characterisation of Archaean microfossils, biomarkers and organic matter: Probing the nature and diversity of early life on Earth. Recognizing biological signatures in ancient rocks poses the single greatest challenge to our understanding of the origin and evolution of life. This Project will use new advanced technology to reveal when and where life first appeared and assess its impact on the environment, atmosphere and climate. Results are essential for understanding the transformation of our planet into a suitable habitat for humankind. The work will place Australia among world leaders in one of the most exciting topics of current scientific research, raising Australia's reputation in this high profile and competitive field. The Project tackles profound questions and seeks to attract, inspire and train future scientists in an ideal location and research environment.Read moreRead less

Enhancing the Monash-VIEPS Stable Isotope Facility. This proposal is to enhance the Monash-Victorian Institute of Earth and Planetary Sciences (VIEPS) Stable Isotope Facility to expand our capacity for state-of-the-art research in hydrogeology, hydrology, aqueous chemistry, modern and palaeoclimatology, sedimentology, geochemistry, economic geology, and biological sciences. This facility will then have an analytical capability that is at least the equal of those elsewhere in Australia and which ....Enhancing the Monash-VIEPS Stable Isotope Facility.

This facility will then have an analytical capability that is at least the equal of those elsewhere in Australia and which will maintain our position as a World Class stable isotope research facility. The enhanced facility will permit new research to be carried out that will lead to new collaborations both within the traditional Earth Sciences and across disciplines.Read moreRead less
Chronostratigraphic, molecular and isotopic approaches to age petroleum. The project aims to reduce the costs of drilling in deep-water offshore by better identifying potential drilling sites. The North-West shelf offshore Australia is the main supplier of liquefied natural gas. However, there is uncertainty about the age of petroleum (oil and gas) discovered in the region. It is not currently possible to constrain an age of fluids to a number of source rocks. The aims are to develop a high-leve ....Chronostratigraphic, molecular and isotopic approaches to age petroleum. The project aims to reduce the costs of drilling in deep-water offshore by better identifying potential drilling sites. The North-West shelf offshore Australia is the main supplier of liquefied natural gas. However, there is uncertainty about the age of petroleum (oil and gas) discovered in the region. It is not currently possible to constrain an age of fluids to a number of source rocks. The aims are to develop a high-level age discriminative tool for fluids. An interdisciplinary approach will be applied using state-of-the-art techniques including comprehensive two dimensional gas chromatography time-of-flight mass spectrometry, compound specific isotope analysis of hydrocarbons, clumped isotopes of methane and metagenomics.Read moreRead less
Investigation of the early history of the moon. The project will address outstanding questions related to the early evolution of planets in the solar system, including the earth, by investigating major events that took place on the moon, where the record of early history is preserved exceptionally well. It will test major models describing the chemical evolution of both the moon and earth.
