Global patterns in Earth’s dynamic topography since the Jurassic: the role of subducted slabs

Abstract: We evaluate the spatial and temporal evolution of Earth’s long-wavelength surface dynamic topography since the Jurassic using a series of high-resolution global mantle convection models. These models are Earth-like in terms of convective vigour, thermal structure, surface heat-flux and the geographic distribution of heterogeneity. The models generate a degree-2-dominated spectrum of dynamic topography with … Read more…

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…
