Why do some slabs stagnate?

Why do some slabs stagnate?

Mechanisms for stab stagnation are essential for understanding the mantle circulation patterns. This week, Diandian Peng, a graduate student from University of Illinois explores how dynamic pressure gradients can pull the slabs sideways stagnating them at the Mantle Transition Zone. Seismic imaging provides critical constraints on the structure and evolution of subducted slabs. Numerous tomographic …[Read More]

Paleogeography and the Northern Hemisphere Oceanic Gateways

Paleogeography and the Northern Hemisphere Oceanic Gateways

Eivind Straume a Postdoctoral fellow at the Department of Geological Sciences within the Jackson School of Geosciences explores how the opening and closing ocean gateways have influenced the Earth’s climate in the past.   Changes in Earth’s geography due to tectonic plate motions and mantle convection influence climate evolution on geological timescales. Over millions of …[Read More]

ST-ECS networking campfire event

ST-ECS networking campfire event

The EGU Solar–Terrestrial physics (ST) division’s early-career scientist (ECS) team is organising a so-called Campfire event to gather the community together before EGU22 and promote networking among ST-ECSs. The event will be held on Zoom and will take place on Friday 18 March 2022 at 15:00 CET, for a duration of one hour. We will …[Read More]

TS Must Read paper – Foreland Basin Systems, DeCelles & Giles (1996)

TS Must Read paper – Foreland Basin Systems, DeCelles & Giles (1996)

Foreland Basin Systems, by DeCelles and Giles (1996), expands the concept of foreland basin into the more comprehensive and integrative concept of foreland basin systems. Foreland basin systems can be defined, as per this TS must-read paper, as compressional regions where various tectonic forces lead to flexural responses of a variable wavelength, which may in …[Read More]

SENSORChat: Go with the UPFLOW – detecting powerful motions deep within Earth’s interior

SENSORChat: Go with the UPFLOW – detecting powerful motions deep within Earth’s interior

“SENSOR” – stands for Seismological Experiments, Network Systems, Observations and Recovery In this blog series, curated by Chiara Civiero, we share news about recent or upcoming seismic experiments around the globe! Could you explain what your project is about? While downward mantle flow (subduction) is well constrained, a grand challenge in Earth sciences is to …[Read More]
