This project aims to understand the role of water in the building of our solar system, Mars and Earth. Surprisingly little is known about key issues surrounding the origin of water and its subsequent recycling on Earth. This project will use new techniques for measuring low abundances of water along with oxygen isotopes, to measure water abundances and oxygen isotopes in meteorites and terrestrial rocks to establish how water was delivered to Earth and to understand how water is geologically recycled. This is expected to have direct bearing on where and how Earth's water originated, how water is retained in mantle and crustal minerals and it will have broad implications for understanding volcanic hazards and formation of ore deposits. This will lead to a new capability for combined water and oxygen isotope analysis in Australian geoscience leading to technological development and commercialisation of instrumentation.

该项目旨在了解水在太阳系、火星和地球构建中的作用。令人惊讶的是，人们对水的起源及其随后在地球上的循环利用的关键问题知之甚少。该项目将使用新技术测量低丰度水和氧同位素，测量陨石和陆地岩石中的水丰度和氧同位素，以确定水是如何输送到地球的，并了解水是如何在地质上循环利用的。预计这将直接关系到地球水的起源和方式、水如何保留在地幔和地壳矿物中，并将对了解火山灾害和矿床的形成产生广泛的影响。 这将为澳大利亚地球科学带来水和氧同位素联合分析的新能力，从而促进仪器的技术发展和商业化。
