Time machine: History and current advances in reconstructing the Earth through deep geological time – an article on Quartz by Steve LeVine. The article is a review of the development of ideas and technologies in reconstructing the Earth through deep time, aimed at understanding supercontinent assembly, breakup and dispersal, starting with Alfred Wegener. The article focusses on research activities in the context of the IGCP 648 project ‘Supercontinent Cycles and Global Geodynamics‘ led by Zheng-Xiang Li. The piece provides some historical context, and highlights the work of a number of leading scientists, postdoctoral researchers and PhD students currently involved in this work. … Read more…
Constraining Absolute Plate Motions Since the Triassic
Abstract: The absolute motion of tectonic plates since Pangea can be derived from observations of hotspot trails, paleomagnetism, or seismic tomography. However, fitting observations is typically carried out in isolation without consideration for the fit to unused data or whether the resulting plate motions are geodynamically plausible. Through the joint evaluation of global hotspot track … Read more…
