Steven B. Shirey and Stephen H. Richardson examined diamond inclusions as samples of ancient mantle processes. They compared inclusion composition and age information to test changes in the delivery of crustal material to the lithospheric mantle.[ref]
Start of the Wilson cycle at 3 Ga shown by diamonds from subcontinental mantle by Steven B. Shirey and Stephen H. Richardson. Abstract: compiled inclusion chemistry and temporal change
The proposed link to the Wilson cycle connects microscopic samples with planetary recycling, while requiring a model for how the samples formed and survived.
