@rockhardIES @GBirkefeldt @EIlyinskaya @theAGU Can't wait!!

Read about our favourite eruption before your neighbour and as a bonus you can enjoy some chic geochemistry photos 🌋

We got visited by @rvkgrapevine for a feature article on why the #Geldingadalir chemistry is special. Incompatible trace elements mentioned.

Zoltán's impressive piece of work makes it easier to analyze sulfur isotope ratios in tiny spots of volcanic glass, like melt inclusions. In other words, geochemists now possess a new superpower! #sulfurlove #SIMS #oneofmanyauthors

Watching (from a safe distance, with camera zoom) the slow and steady advance of incandescent rock. A team from @rockhardIES were back at Fagradalsfjall collecting new samples last Saturday, but not from this part of the lava flow!

Might be the best day at the volcano to date. Sun and 50m fountaning 🌋 AND then we found tephra pieces the size of my fist - what's not to like? Tadaaa! Video by @Tetraheedra

@RobAskew2 @rockhardIES Some days I feel like day 1 Geldingadalur and some days I feel like day 24... 🌋🙄

New updates on our favourite lava from @rockhardIES! 🌋 the lava is becoming chemically enriched over time, which is best explained by melts derived from deeper in the mantle. I'm feeling very lucky to be part of this and getting to study this, the coolest of eruptions 👩‍🔬

[Geochemistry and Petrology Group @ Uni. Iceland @rockhardIES]

Our favourite lava is becomming more eniched over time (increase in K2O/TiO2)😮Seems like the #Geldingadalir eruption is now tapping low degree melts from even deeper in the mantle! 🌋check out regular updates on https://t.co/r2NvXrP6EC

Today another rift opened at #Geldingadalir! 🌋 Ed and @bar_maja were quick to volunteer for fieldwork so we now have fresh new lava samples! Ed practically looks like a real life Harry Dalton, don't you think? #dantespeakref #reallifescience #petrologistsatwork

[Geochemistry and Petrology Group @ Uni. Iceland @rockhardIES]

Bruh it was a cold and windy day in Iceland! But the #Geldingadalir volcano made the trip all worth it! Lots of golden tephra is now drying at @Haskoli_Islands @uni_iceland so we have something to do next week #rocklove #neverbored #safetyfirst

Trace elements & Pb isotope ratios of the #Geldingadalir lava suggest a new batch of magma arriving from the mantle beneath Reykjanes that is distinct from historical eruptions. Full report available here: https://t.co/XAvvYsZpJc

Professor Sally Gibson @GeoSalCam and an international team have shown that volcanic carbon emissions were not a major driver in Earth’s most recent extinction event...read more below👇@GC_CUNY @virginia_tech @UCBerkeley @DrexelUniv

Spot the anomaly on the Reykjanes skyline... 🌋 There's no better view than a volcanic plume in the light of an Icelandic sunset after a sunny day. I can't speak for the mountain below the plume though... Keilir will survive #rocklove #geldingadalsgos #niceview #icelandgeology

Two excited olivine and melt inclusion enthusiasts probing the new #geldingadalsgos lava and showing off beautiful melt inclusions in equally beautiful olivines #olivine #meltinclusions #rocklove @bar_maja

[Maja Bar Rasmussen @bar_maja]

Such beautiful olivines!

[Geochemistry and Petrology Group @ Uni. Iceland @rockhardIES]

Igneous geochemist's favourite materials fresh from #geldingadalir to the lab: Quenched basaltic matrix glass and olivine crystals with beautiful glassy melt inclusions. #highspeedmantleconnection #petrologydream

[Geochemistry and Petrology Group @ Uni. Iceland @rockhardIES]

Our report on petrological and chemical characteristics of the first lava emplaced during the new Geldingadalur eruption in Reykjanes. Turns out the magma is hot and comes straight from the mantle! Have a read for yourself through this link: https://t.co/8dPXUoGiT5

Fyrsta mynd af gosinu. Tekin úr þyrlu Landhelgisgæslunnar. Syðri endi tungunnar er um 2,6 km frá Suðurstrandarvegi. Miðað við fyrstu upplýsingar er sprungan um 200 m löng.

To celebrate the International Women's Day I'd like to share that I recently successfully defended my PhD thesis. It has been an incredible journey and I am grateful to everyone who has helped me along the way. Thank you! And happy women's day! 🌋 @GeoSalCam @HelenWCam

[Maja Bar Rasmussen @bar_maja]

@Penny_Wieser @GeoSalCam @EarthSciCam Thanks, @Penny_Wieser - a novelty and a miracle for sure!

[Sally Gibson @GeoSalCam]

Well done to #MajaRasmussen on the successful defense of her PhD thesis on icelandic olivine with opponents #KevinBurton & #AbigailBaker. Hugely well deseved & to #SaemiHalldorsson. We enjoyed working with you in our labs @EarthSciCam
