Mini Lecture of GRK 2423 FRASCAL Fractures, faults and roughening anti-cracks: pattern formation in Geology Friday, 12 March 2021, 9 am to 4:30pm If you are interested to participate, please write an e-mail to [email protected] to receive the Zoom link #geozentrum #fau

For some reasons I keep seeing faces in my rock samples. This quartz guy gets his nose smashed by a football or so. Ouch! 😵 (SEM CL image of sandstone) #thinsectionthursday

🚨pre-print alert🚨 have you ever seen such strange fracture fill? if yes, tell us!🙂our interpretation and more on deformation-fluid-diagenesis interaction in rift basins here: eartharxiv.org/repository/vie… comments welcome!

Folds are not just pretty, they are also very useful: This Namibian folded Neoproterozoic greywacke serves as a splendid penholder on my desk Geozentrum Nordbayern @unifau #fridayfold

First time on a golf course, driving the cart for a friend. It was fun, but I was more interested in the slumps in the sand bunkers. 🤓

Finally a field trip again, Elba. 1: Leaving for Elba 2: On the ferry 3: Camping spot 4: Mapping on the coast after a swim #geozentrumnordbayern #erlangen #fau #geowissenschaften #geology #elba #fieldtrip

What's better than giving a first field course on Elba since Covid? Giving a second one on Elba just one month later together with Daniel Koehn. 🤗⚒️ Geozentrum Nordbayern

Reviewing work I reviewed before for another journal (editor knows). Authors improved little of the concerns of all reviewers. Seems it's just submitted elsewhere hoping others to miss the issues. I find this extremely disrespectful towards the peers who spend their time with it.

Finally, after 2-year covid-postponement, I was able to go for field work in NW Namibia again. 🥳 Was great to be back. Geology and scenery as fantastic as ever. But temps >40°C just brutal. 😅 Now waiting for my sample shipment. 🤗

Despite all good advice, sometimes staying the night at the work place feels like the right thing to do. 🙂

In the #Karakoram, #Pakistan, there's a hiking trail trench through a glacial lateral moraine. Fairly crazy by itself. 🫣🪨 And then you see beautiful sets of deformation bands there. 🥰

Happy #ThinsectionThursday 🙋‍♂️ what looks in the optical microscrope like rather ordinary, slightly dissolved / altered vein calcite crystals, turns out to be sick crystal growth in cathodoluminescence imagery!? 🧐😯 What the heck happened here? 🤔(scale is in CL image)

A friend sent me these photos from #Petra #Jordan. Does anyone know anything about this? I.e. how the structure (and color variations) in the red layers formed? I'm curious, but not finding literature on it. 🧐 #GeoTwitter

Turbulent flow nicely visualized in a ditch. ⛲️🧐

#MaunaLoa on #Hawaii is erupting for the 1st time since 1984. 🌋 Hiking to the summit was the most surreal trek I ever did. And seeing no one else in two days, seemingly having this massive volcano to myself (+ a horrible headache over night at the crater due to the altitude 🤪)

Until last year, it never crossed my mind writing a paper out of my old BSc-thesis topic. Now, here's the paper 🙃: Comparing extension rates on 2 different timescales in the Eastern California shear zone. pubs.geoscienceworld.org/gsa/geosphere/… #BishopTuff #GPS #VolcanicTableland #FaultScarps
