High resolution timeframe for hominin evolution in the Turkana Basin, Kenya. This project aims to establish a high-resolution timeframe for hominin evolution in the famed Omo-Turkana Basin, Kenya. The Basin hosts a vast array of hominin fossils that cover more than four million years of human evolution, and interbedded volcanic deposits within the Basin sediments has provided much of our current constraints on the timing of hominin evolution. However critical knowledge gaps remain. Using new ins ....High resolution timeframe for hominin evolution in the Turkana Basin, Kenya. This project aims to establish a high-resolution timeframe for hominin evolution in the famed Omo-Turkana Basin, Kenya. The Basin hosts a vast array of hominin fossils that cover more than four million years of human evolution, and interbedded volcanic deposits within the Basin sediments has provided much of our current constraints on the timing of hominin evolution. However critical knowledge gaps remain. Using new instrumentation and dating methods, this project will provide an ultra-precise chronological framework for the basin. This is critical for transforming our understanding of hominin evolution and migration, under changing climatic and environmental conditions.Read moreRead less
Revealing the deep Earth in deep time. This project aims to determine the nature of the chemical and dynamical transformation of the Earth’s interior at the end of the first 25 per cent of its history. This will provide a new understanding of the related establishment of modern surface features such as extensive continents and an oxygenated atmosphere, as well as investigate causal relationships with west Australia’s mineral resources. The expected outcome will be a significant new understandin ....Revealing the deep Earth in deep time.

Mantle evolution and the origin of Earth's atmosphere. This project aims to investigate Earth’s early evolution and the origin of our atmosphere. Using state-of-the-art instrumentation the project will measure noble gas and tungsten isotopes in unique volcanic glasses that record the composition of the Earth’s mantle. These measurements are expected to clarify the relationship between the formation of Earth’s atmosphere, mantle and core, and to generate new knowledge about convective currents ....Mantle evolution and the origin of Earth's atmosphere. This project aims to investigate Earth’s early evolution and the origin of our atmosphere. Using state-of-the-art instrumentation the project will measure noble gas and tungsten isotopes in unique volcanic glasses that record the composition of the Earth’s mantle. These measurements are expected to clarify the relationship between the formation of Earth’s atmosphere, mantle and core, and to generate new knowledge about convective currents in the modern mantle. The project aims to train the next generation of Earth scientists and to provide new knowledge to assist in overcoming the challenges in mitigating climate change and sustaining a resource-based economy.Read moreRead less

Summary
Ultra-precise dating in Earth, planetary and archaeological science. An advanced facility incorporating next generation, multi-collector mass spectrometer and ultra-clean gas line systems, capable of ultra-precise dating of Earth, planetary and archaeological material. This joint Melbourne-Curtin facility seeks to generate ultra-precise age data from ever smaller and younger samples, such as minute particles from space return missions and tiny inclusions in diamonds. The facility is expected to ....Ultra-precise dating in Earth, planetary and archaeological science. An advanced facility incorporating next generation, multi-collector mass spectrometer and ultra-clean gas line systems, capable of ultra-precise dating of Earth, planetary and archaeological material. This joint Melbourne-Curtin facility seeks to generate ultra-precise age data from ever smaller and younger samples, such as minute particles from space return missions and tiny inclusions in diamonds. The facility is expected to revolutionise noble gas dating techniques, resulting in new knowledge on solar system genesis, hominid evolution, indigenous migrations, palaeo-climate change, natural hazards and ore deposit formation, while further enhancing Australia’s international leadership and competitive advantage in the discipline.

Analysis of asteroid samples returned by Hayabusa 2 and Osiris-REx . This year sees the highly anticipated return of the Hayabusa2 spacecraft to Woomera carrying samples of the asteroid Ryugu. This is only the fifth extraterrestrial sample return mission in history. The research team has been invited to participate in the preliminary examination which will take place in Japan in early 2021.

This year sees the highly anticipated return of the Hayabusa2 spacecraft to Woomera carrying samples of the asteroid Ryugu. This is only the fifth extraterrestrial sample return mission in history. The research team has been invited to participate in the preliminary examination which will take place in Japan in early 2021. The investigators have developed unique analytical skills that allow measurement of small amounts of rock for oxygen isotope compositions at unprecedented precision. This project aims to characterise a suite of carbonaceous chondrites, which appear to be the best match to Ryugu, and therefore will provide the exemplar data to understand the provenance of Ryugu, and place it in the context of solar system materials.

The history of accretion in our Solar System. This project aims to determine precise timing of formation and primary melting of asteroids of various compositions, and to trace the stellar sources and mixing processes that caused the compositional diversity of asteroids and planets in our Solar System. This can be attained by comprehensive study of achondrites, meteorites derived from asteroids that were once partially melted. Using the world’s foremost facilities for cosmochemical research in Au ....The history of accretion in our Solar System. This project aims to determine precise timing of formation and primary melting of asteroids of various compositions, and to trace the stellar sources and mixing processes that caused the compositional diversity of asteroids and planets in our Solar System. This can be attained by comprehensive study of achondrites, meteorites derived from asteroids that were once partially melted. Using the world’s foremost facilities for cosmochemical research in Australia and the United States of America, the processes leading to the formation of planets will be explored. This project is intended to advance fundamental knowledge of the environment in which planets emerge and evolve, and the place of our Solar System among planetary systems in the Galaxy.Read moreRead less
Beyond migration and diffusion: The prehistoric mobility of people & ideas. The project plans to build on the strength of current collaborations between archaeologists and geochemists to ask novel questions about the movement of people and ideas in prehistory. The project plans to examine spatial and temporal patterns in population mobility to clarify their relationship with the appearance of new and exotic materials, technologies and practices.

The project plans to build on the strength of current collaborations between archaeologists and geochemists to ask novel questions about the movement of people and ideas in prehistory. The project plans to examine spatial and temporal patterns in population mobility to clarify their relationship with the appearance of new and exotic materials, technologies and practices. The project focuses on the ways in which the movement of individuals and groups of people is both an instigator and a response to sociocultural change, using both key European and Pacific Island examples, to help build a comparative archaeology of phenomena of rapid social and economic change, with pertinence to general theories of innovation and adoption.Read moreRead less
