Tectonic speed limits from plate kinematic reconstructions

Abstract The motion of plates and continents on the planet’s surface are a manifestation of long-term mantle convection and plate tectonics. Present-day plate velocities provide a snapshot of this ongoing process, and have been used to infer controlling factors on the speeds of plates and continents. However, present-day velocities do not capture plate behaviour over … Read more…

The deep Earth origin of the Iceland plume and its effects on regional surface uplift and subsidence

Abstract The present-day seismic structure of the mantle under the North Atlantic Ocean indicates that the Iceland hotspot represents the surface expression of a deep mantle plume, which is thought to have erupted in the North Atlantic domain during the Palaeocene. The spatial and temporal evolution of the plume since its eruption is still highly … Read more…

Australian NW Shelf sediments reveal climate shifts through the eons

Global climate underwent a major reorganization when the Antarctic ice sheet expanded ~14 million years ago (Ma). This event affected global atmospheric circulation, including the strength and position of the westerlies and the Intertropical Convergence Zone (ITCZ), and, therefore, precipitation patterns. Stephen Gallagher, a member of the ARC Basin Genesis Hub node at the Univ. … Read more…

Model of Australia’s Tectonic Stress May Future-Proof Carbon Storage

In response to ever-rising carbon dioxide levels in the atmosphere, some countries are exploring carbon sequestration as a way to mitigate the effects of this greenhouse gas. The general strategy is to inject carbon dioxide more than a mile underground, beneath an impermeable rock layer, where it can dissolve into fluids and crystallize. Injection locations … Read more…

Basin Genesis Hub computer model explains Early Cretaceous eastward flow of ancient Murray River

Murray_RiverAustralia is an outstanding natural laboratory to study the influence of dynamic topography on landscape evolution, having been largely unaffected by tectonic deformation since the Jurassic. Recent studies of the past eastern Australian landscape from present-day longitudinal river profiles and from mantle flow models suggest that the interaction of plate motion with mantle convection accounts for the two phases of large-scale uplift of the region since 120 Ma. … Read more…

EarthByters find that death of ancient ocean between China and Russia triggered mantle upwelling

Flament_Figure5A collaboration between the University of Wollongong, the EarthByte Group at the University of Sydney, the California Institute of Technology and ETH Zürich have solved the mystery of the formation of a recently discovered structure 2,500 km below the city of Perm in Russia.

Earth’s lowermost rocky mantle, just above its iron-rich core, is characterised by two giant hot upwellings under the Pacific Ocean and Africa. Many islands in the Pacific and around Africa owe their volcanic activity to “hotspots” within these large, hot regions deep underneath the surface.  … Read more…

Augury Geodynamics team visits Earthbyte Group in December 2016 in the quest towards Plate Tectonics 2.0

Augury-EarthByte cutout.jpgOur geodynamics collaborators from the Augury Geodynamics Group, Univ. Lyon, are spending the month of December 2016 with the EarthByte Group  to collaborate on a range of issues revolving around seeking improved connections between kinematic (plate tectonic) and dynamic Earth models to advance our understanding and knowledge of the evolution of the solid Earth and the “rules of plate tectonics”. Even though some basic rules of plate tectonics have been accepted since the 70s, these rules are not extensive enough to understand the dynamic, time-dependent interaction between the convecting mantle and the tectonic plates.  The visit is inspired by the move towards Plate Tectonics 2.0 – the development of a unified conceptual and methodological framework to understand how the shallow crust, landscapes, continental margins, and ocean basins interact with the coupled non-linear evolution of the plates and deep Earth through time.
