This project establishes the significance of deformation-related fast-diffusion pathways on the zircon geochemical system and develops intragrain compositional variations as new tools for tracking geological processes. The unique application of zircon to constrain geological processes in numerous Earth Science disciplines over 4.4 billion years of Earth history ensures that results will have far-reaching impact in the Australian and International Earth Science community. As such this project will maintain Australia's leading international reputation in accessory mineral research.

该项目确定了与变形有关的快速扩散路径对锆石地球化学系统的意义，并开发了粒内成分变化作为追踪地质过程的新工具。在超过44亿年的地球历史上，锆石在众多地球科学学科中的独特应用限制了地质过程，确保了这一结果将对澳大利亚和国际地球科学界产生深远影响。因此，该项目将保持澳大利亚在辅助矿物研究方面的国际领先声誉。
