Maybe it is legit?

I saw those new Proclamation coins now in our local AusPost… almost but not quite!

Thortveitite for me, thank you very much #MinCup25

Same

You’d think that “one stop stamp shop” would know its value…

Fun fact, hydration of calcium oxide and calcium silicates to portlandites involves a very large volume expansion at great force, causing all sorts of mayhem in both nature and in my own experiments

How many do you have?

You mean courrectised

It’s antiskarnisation

I do my best 😅

Hope you enjoy it :)

May I interest you in two recent apatite related papers?
doi.org/10.1021/acs....
doi.org/10.1039/D5TB...
Published in chemistry journals so you might have missed them, but very relevant for geoscience.

Camera doesn’t do justice

I should take a video of one of them, aegirine reflects light in a very cool way

Some but not all

Not including another year in a different journal (to be fair, mostly my fault for being slow, NComms were just fine)

Thanks, and it took a while for us to convince the world that it happens. Look at the time gap between submission and acceptance 😅

In carbonatites, alkalis are fluxes that keep melting points low. We discovered that upon reaction with surroundings silicates ("antiskarns"), alkalis are extracted to silicate minerals, solidifying the residual carbonatite magma into crystalline rock.

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

What is qeltite? Good question! See link in reply for the story.

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...

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

Comic. [two people in labcoats look at body pierced with blade draped over bench] PERSON 1: We found him lying uncomformably on the lab bench. 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.

Found in my daughter’s workbook

Close to home, this one is literally five minutes away from my parents house…😬

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.

No, but it misbehaves in many different ways. Paper will be out soon if you’re interested

No, we tried to measure how much carbonate it had using a million different methods and none agreed so we wrote a paper about it
