The principle of ”uniformitarianism”, introduced by the 18th century Scottish geologist James Hutton, has adequately underpinned most geological thinking for over two centuries. The earliest crust on Earth however, cannot readily be explained by observable present-day processes despite simple exponential cooling since the moon-forming giant impact at c. 4.5 Ga.
Recent advances applying micro-analytical tools to rare samples from the earliest Earth are now contributing to a coherent model of Earth’s crustal evolution that can be divided into early single plate, transitional and modern-style multiple plate tectonics.
Martin Whitehouse is Director of Nordsim (the Nordic ion microprobe facility) at the Swedish Museum of Natural History and Adjunct Professor at Stockholm University. He has a DPhil. in geology from the University of Oxford, UK, and pursues research into the development of Earth’s crust, hydro- and atmosphere and early life using isotope geochemistry and geochronology.
