Abstract Inclusion-bearing diamonds from the Koidu kimberlite complex, Sierra Leone (West African Craton) were analyzed in situ for carbon and nitrogen isotope compositions, nitrogen concentrations and nitrogen aggregation states. In a suite of 105 diamonds, 78% contain eclogitic mineral...

Geochemistry of diamonds and their mineral inclusions constraining the composition of the lithospheric mantle and recycling of crustal materials
DownloadFall 2022
Bimineralic eclogite xenoliths from Koidu have been extensively studied previously, but less attention has been directed towards diamondiferous eclogite xenoliths as well as eclogitic and peridotitic diamonds from this locality. To gain insight into the geologic history of the lithospheric mantle...

Lai, Mei Yan, Stachel, Thomas, Stern, Richard A., Li, Kan, Pearson, D. Graham, Harris, Jeff W.
Abstract Eclogitic diamond formation can be associated with interactions between subducted slabs and ambient mantle. To gain a better understanding of the extent of chemical exchange between slabs and ambient mantle and the mechanisms of coeval diamond formation, we examined 16 diamonds with...

This research was motivated by the common recovery of yellow diamonds from kimberlites at Chidliak, Ekati and Qilalugaq in recent years, giving Canada the potential to become the new major source of fancy yellow diamonds. This thesis focuses on the analysis of yellow diamonds recovered from the...
