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.

该项目旨在研究地球的早期演化和大气层的起源。 该项目将使用最先进的仪器测量记录地球地幔成分的独特火山玻璃中的惰性气体和钨同位素。 这些测量有望澄清地球大气层、地幔和地核形成之间的关系，并产生关于现代地幔对流的新知识。该项目旨在培训下一代地球科学家，并提供新知识，以协助克服减缓气候变化和维持资源型经济方面的挑战。
