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…

Decoding earth’s plate tectonic history using sparse geochemical data

Abstract: Accurately mapping plate boundary types and locations through time is essential for understanding the evolution of the plate-mantle system and the exchange of material between the solid Earth and surface environments. However, the complexity of the Earth system and the cryptic nature of the geological record make it difficult to discriminate tectonic environments through … Read more…

Mike Tetley in black and white

Congratulations to PhD candidate Mike Tetley who was awarded a 34th International Geological Congress Travel Grant Scheme for Early-Career Australian and New Zealand Geoscientists. The funds will go towards his current 12-month research visit to Caltech where he is working with Prof Mike Gurnis, a world leader in Earth Dynamics, to study the evolution of … Read more…

History and current advances in reconstructing the Earth through deep geological time

Rodinia 1000 Ma

Rodinia 1000 MaTime 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…
