Onset of Plate Tectonics

  title={Onset of Plate Tectonics},
  author={Martin J. Van Kranendonk},

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… 
Archaean Plate Tectonics in the North Atlantic Craton of West Greenland Revealed by Well-Exposed Horizontal Crustal Tectonics, Island Arcs and Tonalite-Trondhjemite-Granodiorite Complexes
The 700 km-long North Atlantic Craton (NAC) in West Greenland is arguably the best exposed and most continuous section of Eo-to Neoarchaean crust on Earth. This allows a close and essential
A Ca. 2.8‐Ga Plume‐Induced Intraoceanic Arc System in the Eastern North China Craton
The conversion of Archean tectonic regimes from mantle plume to plate tectonic and the mechanism of subduction initiation are two crucial issues in the current Earth sciences. A typical
Neoproterozoic active margin in the northwestern Yangtze Block, South China: new clues from detrital zircon U–Pb geochronology and geochemistry of sedimentary rocks from the Hengdan Group
Abstract The Yangtze Block in South China constitutes an important Precambrian landmass in the present East Asian continent. The Neoproterozoic sedimentary successions of the Hengdan Group in the NW
