What a week @egu.eu. Lots of interesting presentations and fantastic sunny hot weather in Vienna! Sadly, not enough schnitzels! Oh well, maybe next year. @sheared-sash.bsky.social

The return of the pre-EGU fieldtrip through the Austrian Bohemian Massif was a fantastic way to kickoff the conference week. Fantastic weather and fantastic organization made it very enjoyable! Thanks Bernhard, Anna, @sheared-sash.bsky.social and Chris. #egu25 @egu.eu @ts.egu.eu 🪨 🧪⚒️ #geology

It’s been a hot minute since my last #thinsectionthursday but here’s some things I’m working on these days… anyone else having issues with how2plot in MTEX 6.0? I’ve seen some solutions online.. think they’re working but it’s just so random how orientations get flipped without explicit scripting ⚒️🧪

💥 hot off the press and 4 years in the making! My PhD thesis in all its glory! 2 published papers, 1 nearly ready for submission, and an exciting project in the making, all find a home in the pages within. Super proud of my work at Njord w/ Luca Menegon, Kristina Dunkel, & @sheared-sash.bsky.social

Hey everyone, Does anyone have a link to a website where you can search for conflict of interests among research collaborators? A few months ago (~Nov 2024), someone shared a link but I haven’t been able to find it or something similar with a google search. 🧪 ⚒️

🚨 Hot off the press 🪨 ⚒️ Where do you come from, where do you go 🎶 fluids that is… after an earthquake in the dry lower crust? We look into this and more using SEM-CL, EBSD, EMPA, STEM, and FTIR! Hit the link below 👇 agupubs.onlinelibrary.wiley.com/doi/full/10....

🪨⚒️ #thinsectionthursday of a recrystallized quenched frictional melt (pseudotachylyte) from Lofoten, Norway. Plagioclase survivor clast retains deformation twins, reaction between garnet-amphibole. Garnet cores are full of inclusions from rapid quenching growth, then slow growth to form facet GB🧪 🔬

This is a map showing the orientation of diopside in a deformed symplectite. This used to be an omphacite, which tells us that the rock used to be at very high pressure (great depth). ⚒️🧪 If you want to read more about how such symplectites nucleate and deform: link.springer.com/article/10.1...

One of the many perks living and working at the University of Oslo. Winter mornings are just perfect up here. Sunrise at 8:40am this morning. Could use a little bit of snow in the city❄️ 🔬⚒️🪨🧪

⚒️🪨 #thinsectionthursday on a quartz mylonite from… my iPhone camera roll 😂. Could be from the teaching collection or from Australia 🤷🏻‍♂️ I particularly like the “Hawaiian flower” partially recrystallized grain in the lower ribbon. Aloha! 🧪🔬

Brittle? Ductile? Brittle-ductile? If you are interested in why rocks deform the way they do, consider submitting an abstract to our session at #EGU25! The deadline to apply for travel support is on December 2nd! meetingorganizer.copernicus.org/EGU25/sessio...

🪨⚒️ Just received my advanced copy of Haakon’s and Christian’s latest textbook, Plate Tectonics. Will be a nice complementary next to these other beauties #earth-sciences 🔬🧪 #geology

NSF makes you say who you got conflicts (coauthored) with. We (really just Jordan Matelsky) just built you a tool for that. Literally one click: bib.experiments.kordinglab.com/nsf-coa

⚒️🪨 #thinsectionthursday of a corona of garnet enveloping (a weird) biotite within an anorthosite from Lofoten, Norway. This sample was drilled in what we thought was relatively undeformed rock, but plagioclase loves to form tapering deformation twins… so how deformed is undeformed? 🧐 #earth-sciences

I woke up to a bunch of new followers, so I should share some things that we do here at the Njord Centre, University of Oslo. Here is my JGR: Solid Earth paper on porosity in lower crustal faults and ductile shear zones using microCT, EBSD, SEM-CL. agupubs.onlinelibrary.wiley.com/doi/abs/10.1...
