Revised ~1 Ga age of Stac Fada impact site in Scotland from shocked zircon grains and links to oldest known non-marine microfossils in the UK. Check it out #openaccess in #Geology
Global collab with @JDLCentre, @NASA and St. Andrews

Shoutout to @priyanjan_datta for the 1st paper of his #PhD in #Lithos linking granite Pb-isotope signatures to intracrustal fractionation and crustal thickness, and the evolution of the Lachlan Fold Belt.
Collab with @JDLCentre & @GeoscienceAus

Hot off the press, published #openaccess in @theAGU's G3 and led by PhD student Lucy Mathieson, explore the potential treasure trove of #discordant data in U/Pb #zircon #geochronology.

In collaboration with @DEMIRS_WA we have 2 fully funded #PhD positions available looking at the "Tectonic Evolution and Geochronology of the Yilgarn Craton" a world famous mineral endowed classic of WA geology.

New #CurtinResearch has uncovered the world’s oldest meteorite crater in #WesternAustralia’s #Pilbara region – 3.5 billion years old! Led by Professors Tim Johnson and Chris Kirkland, this find could reshape Earth’s history. #EarthScience #MeteoriteImpact

[Timescales of Mineral Systems Group @TimescalesEPS]

"Extreme Crustal Fractionation in a Proterozoic Chemical Hotspot" by Liebmann et al. linking exceptionally high radiogenic heat production and some of the world’s largest ore deposits - a great #collab with @JDLCentre, @GeoscienceAus & @UniMelb.

#openaccess in @NatureComms shatter cone evidence for the worlds oldest known impact crater in ~3.5 Ga #Archaean rocks of the Pilbara. Led by @ChronKirkland, with @early_earth_tim, @DEMIRS_WA and @JDLCentre et al.

The crater dates back 3.5 billion years, making it the oldest known by more than a billion years. @TimescalesEPS @jonas_kampf @CurtinUni https://t.co/aWL1mr31Ya

#openaccess paper in #Geology led by @MaxDroellner in collaboration with @JDLCentre.
Check out the power of detrital rutile double dating (U-Pb + (U-Th)/He) to track thermal histories, improve sediment provenance and much much more!

@RibeiroBrunov @chrisfpclark @early_earth_tim @within_somethin Thanks mate! 🙏

[Jonas Kämpf @jonas_kampf]

Interested in UHT metamorphism and its implications for in situ Lu–Hf garnet dating? Then check out our latest paper! We integrate #garnet and #monazite petrochronology to unravel the polymetamorphic history of an Archean granulite from the Dharwar Craton:

@LeeBlake90917 They have been extensively fractured and sheared.

Haven't posted in a while, but enjoy this #pseudotachylyte in a high-grade metapelite from #IncredibleIndia for #ThinSectionThursday. Poor garnet got smeared out quite a bit producing some cool microstructures🔬 #geology #petrography #garnet

[Jonas Kämpf @jonas_kampf]

@Mitchell_Duan Technically yes, but in reality you would need garnets that have high Lu to achieve a reasonable precision. Not sure if others have tried, but I'm assuming that 'regular' metamorphic garnets of that age will likely yield very imprecise dates...

[Jonas Kämpf @jonas_kampf]

We dated Earth's oldest #garnets (to my knowledge). Check it out!

[Jonas Kämpf @jonas_kampf]

@Mtipha_ Not at the moment. There are some P–T studies from this area looking at mafic granulites and garnet-kyanite schists though

[Jonas Kämpf @jonas_kampf]

@RibeiroBrunov You should go there, any sample you pick up will be amazing 😆
