Objective
Diamonds provide us with pristine samples of the deepest derived solid and fluid material that we can sample from the interior of the Earth. Inclusions in diamonds have been in isolation since their entrapment and allow a glimpse to the depths of the mantl e and far back in time. Diamond ages, inferred from dating mineral inclusions trapped within, are subject to some uncertainty due the precise nature of the relationship between the solid inclusion and the diamond. Most diamonds grow from fluids. Direct dat ing of these parental fluids removes any genetic ambiguity that affects the dating of solid inclusions. In addition, knowing the age of the fluid allows us to track temporal changes in deep Earth fluids. The growth structure of fibrous diamonds is conduciv e to trapping diamond-forming fluid micro-inclusions in great abundance. These diamonds enable, for the first time, direct dating of the diamond itself. I propose to date fluid-rich diamonds to compare their age, isotopic and trace element composition. The data will be compared with that of other diamonds and with the ages and isotopic composition of the host kimberlites. Their isotopic compositions will be used to constrain the origin of diamond-forming fluids. The results will bear on the role of the dia mond-forming fluids found in fibrous diamonds to the formation of most other diamonds, including gem diamonds. The results will enable evaluation of the idea that kimberlites and diamond forming fluids evolve from a similar parental melt and will be import ant for understanding the origin, roll and composition of volatile rich fluids in the mantle, in the context of bulk Earth volatile budgets. The applicant will bring skills in micro- and nano-analysis techniques and will be trained in the latest ultra-low level radiogenic isotope chemistry and mass spectrometry methods using the newest instrumentation. She will work closely with a leading European mass spectrometry company, developing specialist techniques.
