Fleshing out the fossil record: using organically preserved soft tissues and bone to explore the evolution of unique vertebrate characters. This study integrates developmental, molecular and morphological data in both fossil and living species to provide insights into the evolutionary mechanisms which formed the musculo/skeletal system. Uncovering these evolutionary pathways has the potential to describe mechanisms common to all vertebrate and informs us about our own evolution.
Lifting the veil on the Geological Dark Ages: The search for Hadean Crust on Earth. The project involves detailed field and isotopic study of some of the oldest known rocks and minerals to develop the first comprehensive picture of the earliest growth of the Australian continent. The data will reveal the timing and processes of continent formation and shed new light on the enigmatic early period of the Earth's evolution.
Roles of deep-Earth fluid cycling in the generation of intra-continental magmatism. This project aims to test a provocative and potentially ground-breaking hypothesis that fluid released from subducted oceanic slabs and stored in the mantle transition zone, may trigger or control some major intra-plate geotectonic phenomena. It aims to provide a self-consistent model that links geological processes occurring at plate boundaries with those far-field effects well away from plate boundaries via dee ....Roles of deep-Earth fluid cycling in the generation of intra-continental magmatism. This project aims to test a provocative and potentially ground-breaking hypothesis that fluid released from subducted oceanic slabs and stored in the mantle transition zone, may trigger or control some major intra-plate geotectonic phenomena. It aims to provide a self-consistent model that links geological processes occurring at plate boundaries with those far-field effects well away from plate boundaries via deep-Earth fluid cycling. The outcomes of this project aim to help to better understand links between plume and plate tectonic processes in the first-order dynamic system of Earth, and identify ways to improve success in future mineral exploration.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
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.
A detrital apatite archive to track crustal growth. This project will establish apatite as a new tool to study the evolution of the continental crust. The crust shaped the composition of the atmosphere and the oceans with consequences for the evolution of life through the availability of oxygen and nutrients. However, when and how the continental crust was generated remains a core question. Current models for continental crust development rely on the mineral zircon. However, zircons only record ....A detrital apatite archive to track crustal growth. This project will establish apatite as a new tool to study the evolution of the continental crust. The crust shaped the composition of the atmosphere and the oceans with consequences for the evolution of life through the availability of oxygen and nutrients. However, when and how the continental crust was generated remains a core question. Current models for continental crust development rely on the mineral zircon. However, zircons only record the history of evolved rocks. To address this bias we will use the mineral apatite which forms in less evolved rocks. We will develop a detrital apatite database of Pb-Nd (model) ages and integrate this with the zircon record to provide a more holistic description for how our planet developed.Read moreRead less

This project aims to provide new insights into the origin of life on Earth, life’s diversification through the Precambrian, and the co-evolution of life and early Earth environments. It will be discipline-leading in that it will take the study of early life to the sub-micrometre and hence sub-cellular level. This will facilitate new opportunities for identifying the types of life present during early Earth history, their metabolisms, cellular chemistry and interactions with their environment. This project aims to also provide new search engines and more robust assessment criteria for life on other planets, and help to resolve specific scientific controversies, for example, the validity of claims for cellular life from 3.5 billion-year-old rocks.Read moreRead less
Deep-sea coral ocean-climate records of the last glacial and recent eras. The project aims to predict the ocean carbon dioxide sink’s long-term capacity and future trajectories of global warming and increasing carbon dioxide. This project will use geochemical proxies encoded in the skeletons of deep-sea corals in the Perth Canyon, Tasman seas, and Antarctica, in the heart of the ocean-climate system, to reveal continuous long-term records of environmental change at annual-decadal resolution for ....Deep-sea coral ocean-climate records of the last glacial and recent eras. The project aims to predict the ocean carbon dioxide sink’s long-term capacity and future trajectories of global warming and increasing carbon dioxide. This project will use geochemical proxies encoded in the skeletons of deep-sea corals in the Perth Canyon, Tasman seas, and Antarctica, in the heart of the ocean-climate system, to reveal continuous long-term records of environmental change at annual-decadal resolution for our recent past (hundreds to thousands of years) and the Last Glacial Maximum. These records are expected to provide a more accurate understanding of Earth’s long-term responses to anthropogenic carbon dioxide emissions and global warming.Read moreRead less

Water is essential for human existence, indeed for life's beginning. The circulation of water between the surface and the deep interior lubricates the internal dynamics that keep Earth geologically alive; it is crucial to most Earth systems, including the evolution of the hydrospher/atmosphere/biosphere, and the development of giant ore deposits. However, the origin, abundance, speciation and movements of fluids inside Earth are largely unknown, and represent key issues in modern geoscience. This CoE will integrate previously disparate fields - geology, tectonics, geochemistry, petrophysics, geophysics and dynamic modelling - to understand the workings of Earth's deep plumbing system.Read moreRead less
