The breakup of the supercontinent Gondwana set off a chain of tectonic events that eventually uplifted parts of East Antarctica, creating the perfect conditions for the formation of an ice sheet, a new study suggests. eos.org/articles/the...

The Breakup of Gondwana Over 100 Million Years Ago May Be Why Antarctica Has Ice Today - Eos

A rift event set off a domino effect of geologic processes that created conditions ripe for Antarctica’s glaciation, a new study suggests.

Fascinating piece in The Conversation by @gernon.bsky.social discussing recent work by him and his colleagues investigating how continental breakup and consequent mantle dynamics may have primed the topography of Antarctica for glaciation ~34 million years ago. theconversation.com/why-antarcti...

Why Antarctica froze millions of years before the Arctic – new research

New solutions to two interlinked mysteries reveal how and why the Antarctic’s enormous ice sheet formed.

Our new study on how uplifting terrain in Antarctica helped provoke glaciation is out @science.org. Delighted to see this work through after many years. www.science.org/doi/10.1126/... @sasbrune.bsky.social @gfz.bsky.social @derekkeir.bsky.social @polarguy.bsky.social @unisouthampton.bsky.social

Continental breakup–driven uplift instigated East Antarctic Ice Sheet formation

Why Antarctica became glaciated ∼34 million years ago (Ma) remains debated, as relatively warm climates and sea temperatures appear inconsistent with ice sheet formation. Although a critical decline i...

🚨 Interested in green energy research? 🚨 ⚒️ I contributed to a 3sat NANO documentary on natural H2 gas, a potential green energy to be found in mountain ranges such as the Alps and Pyrenees 😃 Check out the docu here (from ca. 8 min on, past the fake food story ➡️): www.3sat.de/wissen/nano/...

@alarosa.bsky.social new paper of dike intrusion at Erta Ale in July 2025 now out www.frontiersin.org/articles/10.... @sorcerinsar.bsky.social @sasbrune.bsky.social @wattsvolcanology.bsky.social

Frontiers | Segmented dike intrusion linked to multi-level magma storage during and before the 2025 eruption at Erta Ale (East Africa)

IntroductionDike intrusions can assist continental rifting and plate divergence. However, our understanding of the magma dynamics during diking and the archi...

Many oceanic islands far from active plate tectonic boundaries contain materials clearly originating from continents, even though they are located in the middle of an oceanic plate. Where do the continental remnants come from? @sasbrune.bsky.social, and lead author Thomas Gernon from 1/5

A mosaic-like picture with many colours showing a thin slice of rock under a microscope. This is a fragment of the lowermost continental mantle — the crystalline roots of the continents. This is the type of material that the authors propose is stripped away and laterally transported into the oceanic mantle. (Photo: Prof. Tom Gernon (University of Southampton).)

Our new study on @egu.eu SE combines automatic fault mapping, geodesy and rock dating to reconstruct the tectonic and magmatic evolution of the Afar rift during the last 4.5 Myrs. @sasbrune.bsky.social @sorcerinsar.bsky.social @derekkeir.bsky.social @gimmi-p.bsky.social @earth-science.bsky.social

Cross-scale strain analysis in the Afar rift (East Africa) from automatic fault mapping and geodesy

Abstract. The formation of continental rift systems is characterised by the interplay of magmatic and tectonic processes. Their evolution involves a wide range of timescales, from centennial scales of...

Applying for a PhD in Geoscience: To do or not to do

Fresh out of your bachelor’s degree, or more commonly these days, your master’s degree, it can be tempting to pursue your PhD as quickly as possible. While there are compelling reasons to dive straigh...

🌍 Earth’s mantle flow has changed over time. Mineral phase shifts can stall plumes and reshape convection. Read more in today’s EGU Geodynamics blog by Ranpeng Li (GEOMAR, Kiel): blogs.egu.eu/divisions/gd... #EGU #egugeodynamics #mantleplume

Phase transitions control plume layering during Earth’s secular cooling

Earth’s structure and dynamics have evolved quite a lot since its formation, and so has mantle dynamics and convection patterns changed along with it. It turns out that phase transition in certain man...
