The project will provide a better understanding of the mantle source regions of diamonds and, in particular, homogeneity/heterogeneity of the source regions as a function of space and time - potentially of economic significance for diamond exploration. The project will investigate the noble gas compositions of a systematic selection of diamonds of different ages and from different parts of the mantle. Together with carbon and nitrogen isotope systematics, this information will be used to better constrain models of Earth outgassing and the evolution of the Earth's atmosphere and mantle.

该项目将使人们更好地了解钻石的地幔源区，特别是源区的同质性/异质性随空间和时间的变化-这对钻石勘探可能具有经济意义。该项目将系统地调查地幔不同部分不同年龄钻石的惰性气体成分。与碳和氮同位素系统学一起，这些信息将用于更好地约束地球释气模型以及地球大气和地幔的演变。
