Come work in our lab group! Looking for a TEM or Microprobe specialist, with opportunities to participate in a range of planetary science projects.

Felt that one! When a giant meteoroid struck Mars, the seismometer aboard our NASA InSight lander sensed it – and our Mars Reconnaissance Orbiter has the visual evidence. See more about how the robotic explorers teamed up to capture the moment: go.nasa.gov/3WbKiD6

There’s a defect in my hexagonal packing. Happy 6th night of Hanukkah! Thankful for the father in laws latke recipe

Please join us in congratulating Amanda Stadermann, who today successfully defended her Ph.D. Dissertation, Investigation into Igneous Lithologies and Impact Processes in the Earth-Moon System. Congrats, Amanda! 📸: Amanda is pictured with her advisor, Dr. Jessica Barnes.

Shock, feldspar, Pb-isotopes, and of course the Yarrabubba impact structure. How else would you want to start your Friday?

Why isnt there a sedimentology podcast called Off the Shelf? This is troubling me on a random Sunday

Nice The Conversation - Australia + New Zealand piece on our recent #EPSL paper looking at crustal modification via large impacts and tracked through #feldspar Pb isotopes theconversation.com/how-the-worlds…

📢 Want to do some geology in India, Africa or Norway. We have four PhD projects in metamorphic geology and geochronology available at Curtin University in Perth, Western Australia. See the ad below for further details! ⁦Curtin University⁩ earthworks-jobs.com/geoscience/cur…

Do you know The Beatles' Magical Mystery Tour? Well, we have a Magical Mystery Meteorite 💫 Tour for you today. Not far from today's course at Rochechouart 🕍🌠 🏰 a huge meteorite hit the earth. How do we now because obviously we were not there to witness this 👀 Well

Who doesn’t love racing through an impact structure. Especially one with some amazing shocked zircons doi.org/10.1111/maps.1…

some nice coordinated NanoSIMS/TEM analysis of presolar grains in Ryugu samples from our group and the Hayabusa2 team!science.org/doi/10.1126/sc…

After the #OSIRISREx asteroid sample lands on Sept. 24, it will head to Houston where it will be curated and preserved by our team here at Johnson! The sample could provide insights into how planets formed and life began. Learn more: go.nasa.gov/43PoK2y

American Mineralogist: Microstructural changes and Pb mobility during the zircon to reidite transformation: implications for planetary impact chronology doi.org/10.2138/am-202… Szumila et al. explore laboratory shock-induced physical and chemical changes to zircon and feldspar.

Tabb °C Prissel, PhD et al. dive into lunar mantle overturn and how it impacts the rapid transition from primary to secondary crust building on the Moon hxxfrd nature.com/articles/s4146…

Evidence for Extrusive Mg-Suite Magmatism on the Moon? Fine-Grained Magnesian Clasts in an Apollo 16 Impact Melt Breccia doi.org/10.1029/2022JE… Some of the fine-grained lunar Mg-rich clasts may be volcanic in origin, while others are likely crystalline impact melt

So happy that my first PhD paper is out! We looked at #zircon microstructures and reported evidence of precursor cubic zirconia for the first time at the West Clearwater Lake impact structure in #Canada Gordon Oz Osinski DrTMNZ

A team of int'l scientists recently examined #Zircon microstructures at the West Clearwater Lake impact structure, Canada as a record of high temperature & pressure conditions during impact melt evolution. Learn more in Earth & Planetary Science Letters: tinyurl.com/vpxusnr3

New article in Nature Geoscience led by Hamed GAMALELDIEN with Chris Kirkland, Tim E Johnson and others on #Oisotopes in #zircon and #earlyEarth water

We are currently advertising for a new #fullyfunded #PhD position in collaboration with the Geological Survey of Western Australia on Early Earth Isotope Geochemistry. Open until filled but expected to be in position by March 2025 - scholarships.curtin.edu.au/Scholarship/?i…
