Diamonds Make a Craton Bigger

Baffin Island Kimberlites and the North Atlantic Craton

A correspondent has brought THIS ARTICLE to my attention. Researchers working on kimberlites in southern Baffin Island found that wall rocks brought to the surface by the kimberlites bore evidence that they were part of the North Atlantic Craton. 

This increases the craton's size by 10%. You can find more from HERE, and for the truly dedicated HERE. If you are dedicated and solvent and want to investigate further look HERE.
