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…

Summer Vacation Internships with Chevron.

Applications are invited for summer internships with Chevron. The program offers students the opportunity to work collaboratively with a team to discover new energy reserves by focusing on a producing field or exploration project. The intake is from late November to February (12 Weeks) during the summer vacation period. The work will be paid, with … Read more…

Earth is estimated to be around 4.5 billion years old, with life first appearing around 3 billion years ago.

EarthByter Andrew Merdith, Alan Collins from the Univ. of Adelaide and colleagues produced an animated plate tectonic map that changes the history of our planet as we know it. Of course it’s not just an animation, it’s an elaborate computer model that took years to be built, assimilating tons of geological and geophysical observations, in a … 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…
