The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Deciphering the early Solar System chronology and planetary chemistry using isotope systematics of meteoritic zircon. This project addresses the early evolution of our Solar System that is one of the most important questions in Earth and Planetary sciences. It will use Australia's meteorites and innovative analytical techniques developed in Australia.

This project addresses the early evolution of our Solar System that is one of the most important questions in Earth and Planetary sciences. It will use Australia's meteorites and innovative analytical techniques developed in Australia. High impact scientific results produced in this project will be to the national benefit in terms of international recognition of our unique capability in this high profile and competitive research field. Furthermore, by providing new constraints on the initial state of geochemical evolution of the terrestrial planets, this work will further our knowledge of the subsequent evolution of the Earth's mantle and crust, leading to better models for Australian continent development and its deep-Earth resources.Read moreRead less
Early Evolution of the Solar System: A Planetary Perspective. A geochemical study of early solar system materials will be conducted to investigate physical conditions leading to assembly of the terrestrial planets, and the chronology of early geological events that shaped the Earth and Moon. Objects from the solar nebula and samples from the Earth, Moon, Mars, and differentiated asteroids will be studied. This research will contribute toward understanding the astrophysical environment of the inn ....Early Evolution of the Solar System: A Planetary Perspective. A geochemical study of early solar system materials will be conducted to investigate physical conditions leading to assembly of the terrestrial planets, and the chronology of early geological events that shaped the Earth and Moon. Objects from the solar nebula and samples from the Earth, Moon, Mars, and differentiated asteroids will be studied. This research will contribute toward understanding the astrophysical environment of the inner solar system, establish a high-resolution absolute timescale for early geological events, and Identify the population of solid bodies present during the initial stages of planetary development.Read moreRead less
Lithic Astronomy: The age and origin of the elements and their incorporation in the solar nebula. All heavy elements are produced in stars. The signature of nucleosynthesis is the isotopic composition of the elements and thus measurement of isotopic compositions allows nuclear astrophysics to be elucidated in the laboratory. This project will examine the linkages between stellar sites and the material in our solar system through measurement of interstellar grains and other primitive material ob ....Lithic Astronomy: The age and origin of the elements and their incorporation in the solar nebula. All heavy elements are produced in stars. The signature of nucleosynthesis is the isotopic composition of the elements and thus measurement of isotopic compositions allows nuclear astrophysics to be elucidated in the laboratory. This project will examine the linkages between stellar sites and the material in our solar system through measurement of interstellar grains and other primitive material obtained from meteorites. A chronology of processes affecting the solar nebula will be determined through measurement of radionuclides. Th/U measurements in presolar grains could allow a view of galactic chemical evolution billions of years prior to the solar nebula.Read moreRead less
Sources and processes in the early solar system - an isotopic study. Our solar system formed over 4.5 billion years ago. We aim to develop techniques that will allow us to determine the sequence of events that led to our planetary system with unprecedented detail. The same techniques can be applied to dating geological events, for example, correlating ore-forming events and dating opal formation. This project utilizes new Australian technologies that will have potential economic benefits both ....Sources and processes in the early solar system - an isotopic study.
