Experimental and natural constraints on trace element and volatile recycling in subduction zones

这个项目的结果将对地球的分化提供重要的限制，最终导致适合采矿的元素的集中。俯冲带微量元素和挥发性物质的回收利用是“地球中心之旅”研究主题的组成部分，该主题已被确定为国家地球科学战略计划的重点项目（4.4）。俯冲带的二氧化碳循环对我们了解地球上温室气体的长期变化至关重要。澳大利亚国立大学在实验岩石学和地球化学方面是世界领先的研究机构之一，该项目的成果将确保澳大利亚在这些学科中保持领先地位。

The results of this project will provide important constraints on the differentiation of Earth, which ultimately leads to the concentration of elements suitable for mining. Trace element and volatile recycling in subduction zones is an integral part of the research theme 'Journey to the centre of the Earth' which has been identified as a key project (4.4) in the national strategic plan for geosciences. CO2 recycling in subduction zones is crucial for our understanding of the long-term greenhouse gas variations on Earth. The ANU is one of the world-leading research institutions in experimental petrology and geochemistry, and the outcomes of this project will ensure that Australia remains at the forefront in these disciplines.
