Considering this graphic from the Wang et al. (2019) paper on exhumation of eclogites. [ source agupubs.onlinelibrary.wiley.com/doi/10.1029/... ] I have some critique. ⚒️
A "cartoon" cross-sectional view of a subduction zone, showing sites of subduction erosion, exhumation, and exhumation stagnation.

What happened to Mike Morrison's "Better Poster"? I used to see this design occasionally several years ago, but in recent conferences it's back to 99% "wall of text" style. Did we forget about this amazing thing?

The amount of antisemitism I’m seeing here, even from fellow earth scientists I have interacted with quite a lot in the old Twitter days, is disappointing.

How do you get copper in post-subduction porphyry deposits? You flush ancient sulfide cumulates with deeper oxidised magmas! New paper out now with Shiwei Wang from Hefei UoT as lead author: www.nature.com/articles/s43...

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. Mathematicians were aghast. (5/n)

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. What an ass.

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.

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.

#ThinSectionThursday 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.

A nice schist with muscovite, kyanite/sillimanite, chlorite, and twinned plagioclase. #thinsectionthursday #geology #science #minerals #rocks
An image of a rock in thin section, displaying crystals of various minerals (kyanite, sillimanite, muscovite, chlorite, plagioclase). A schistose texture is observed, with the muscovite being aligned and appearing to 'flow' from top right to bottom left of the image.
