Home again after a fantastic time in the Barberton Greenstone Belt.

The 2nd week was spent studying the formation of sulfate minerals more than 3.2 billion years ago - with a great team, beautiful sunsets and spectacular outcrops. So long 🇿🇦!

#TeamSulfateConcretions @uibgeo

[Desiree Roerdink @DesireeRrdnk]

Teamwork makes the dream work ♥️

Fantastic to lead this team in the field with long-term collaborators Paul Mason @UUEarthSciences and Mark van Zuilen, soon-to-start PhD student Friedrich, and MSc student Enza @uibgeo @CDeepSea.

It has been a fantastic week with colleagues in the Barberton Greenstone Belt 🇿🇦 discussing Earth's earliest surface environments as recorded in the 3.22 billion year old Moodies Group.

One PhD student finished, one MSc student finished, and received funding for a field course on Milos 🇬🇷 - a pretty good week @uibgeo 😃 Thrilled to head to Milos later this year and see some amazing rocks - including a modern BIF 😍

Student and interested to join? Check 👇

PhD position available working with @DesireeRrdnk at Bergen on sulphur isotopes in 3.22 Ga sulphate concretions from the Moodies Group, SA. This is amazingly preserved material recently drilled as part of the BASE project. #geology

Great work by PhD student Apolline Samin @uibgeo @CDeepSea @mohnfoundation and collaborators!

[Desiree Roerdink @DesireeRrdnk]

Another paper published! 🎉

We show that Cu isotope ratios from hydrothermal vent fluids can be recorded in paired hydrothermal chimneys - but only in the very innermost conduit, as alteration of chalcopyrite by intruding seawater shifts Cu isotope ratios to higher values.

[Desiree Roerdink @DesireeRrdnk]

New paper out! 🎉🥳

Results of several MSc projects, one PhD project and my postdoc are now finally published in Frontiers in Marine Science #teamwork @uibgeo @CDeepSea

15 years ago, I was working in this same lab with the same columns to prepare samples for my MSc research...

...today I am working for a week at @VUamsterdam funded by @europlanetmedia to measure silicon isotopes in Archean cherts from South Africa 😁

#WomenInSTEM #TimeFlies

[Desiree Roerdink @DesireeRrdnk]

Not sure what to do this Sunday evening?

If you're in The Netherlands, tune in to NPO2 at 19.30 and learn about early Earth and early life with @govertschilling and me in #Govert naar de kern van de Aarde!

Making most of the sunny weather in Berlin @icdpDrilling - Barberton Archean Surface Environments (BASE) core sampling in full progress:

35 scientists, 8 drill cores, 2500+ meters of rock representing the oldest preserved transition from sea to land
