Diamonds – Time Capsules of Ancient Mantle Volatiles and the Key to Dynamic Earth Evolution

该项目旨在调和基于地球化学(主要是惰性气体)和地球物理数据的关于地幔结构的截然不同的观点。这一目标将通过对特征良好的钻石样品进行创新的惰性气体分析来实现，包括用于先前测年研究的宝石。结合碳同位素结果，这一信息将被用来限制地幔的结构和时空演变。一个相关的成果将是更好地了解钻石和钻石形成的地幔来源区域。

This project aims to reconcile the radically different views on the structure of the Earth’s mantle, based on geochemical (mostly noble gas) and geophysical data. This objective will be addressed through innovative noble gas analyses of well-characterised diamond samples, including gem-stones used for previous dating studies. In combination with carbon isotopic results, this information will be used to constrain the structure and temporal/spatial evolution of the Earth’s mantle. A related outcome will be an improved understanding of the mantle source regions of diamonds and diamond formation.
