How do you get copper in post-subduction porphyry deposits? You flush ancient sulfide cumulates with deeper oxidised magmas!

No matter how far you zoom in it's all sharp corners. Any finite stretch along the x-axis becomes a terrible mouth lined with infinite teeth. Every pointed sliver opens up into a thousand hungry little razors.

And he then *asked himself a question* which he then answered for a further 3-4 minutes before finally getting off the stage. I can't even remember what the talk was about.

Thortveitite for me, thank you very much #MinCup25
Was it quietly grinding on your soul that the #MinCup25 bracket was off-center and oh-so-slightly asymmetrical? We fixed it!
No changes to the matchups, it’s just a lil bit more polished.

New paper: we discovered a new way for magmas to crystallise (!), and it also made one of the largest known carbonatite REE deposits.

We tried to measure an apatite composition using many different methods and failed miserably, so we wrote a paper about it.

Silica substituted carbonate apatite: synthesis and analytical challenges
We use a high temperature experiment to demonstrate a coupled substitution mechanism for carbonate and silica in apatite, namely 2PO3−4 → SiO4−4 + CO2−3, with carbonate substituting for phosphate (typ...

I wonder if the iron-rich intrusion in his back is related. PERSON 2 with ponytail: It could be clastic. Maybe a rift opened in his body, and the intrusive material later fell into the hole.

Pro writing tip: When proof-reading a paper before submission or revision, change the font and print it out on paper. Trust me, you will find so many mistakes you had no idea were there, even though you've read the thing a million times on your computer screen.

This isn't outer space—this is a reflected light image of silicate glass at ×100 magnification with immersion oil. Bright dots are nanonuggets of mostly silver, but also other elements such as platinum, palladium, and bismuth. Their colour correlates with crystal size.
