Analysis of diamonds from the subcontinental mantle reveals that plate tectonics started 3 billion years ago. The further back we look into the geological past, the more obscured the view, masked by an increasingly fragmentary geological record. This has resulted in a controversy on the rates and mechanisms of early continental crust formation and whether plate tectonics—the dominant crust-forming process over at least the past 2.5 billion years—operated the same way, or even at all, during…
