Scars from the world's first deep sea mining test 50 years on
Half a century after the world's first deep sea mining tests picked nodules from the seafloor off the US east coast, the damage has barely begun to heal.

Or geologists… all those lovely rocks on the path need a quick glance…

Was really struggling with working today - turns out it’s Beltane, so I should really be leaping over bonfires and celebrating fertility rituals, which explains everything 🤣

Lovely Easter in Yorkshire, although I think I look happiest on the least sunny day 😂

A nice schist with muscovite, kyanite/sillimanite, chlorite, and twinned plagioclase.

🔬Microscopy Thursday!

🌿Did you know that plants can grow crystals? Here is a piece of oak with Ca-oxalates growing in its cells. In some plants, oxalate crystals form ~80% of their dry mass. In humans, they make kidney stones.

As a museum professional, this is worrying (but not surprising)

A local #ThinSectionThursday today. Clinopyroxene- and olivine-phyric basalt from Holyrood Park, Edinburgh. Location given as St Anthony's Chapel, so probably lava two or three of the Arthur's Seat lava succession.

This crazy #mineral (abhurite) occurs exclusively on tin ingots in shipwrecks!! 😮
It’s formed by the chemical reaction between tin & seawater.
This SEM image from @amgueddfacymru.bsky.social shows tin ingots coated with abhurite from the SS Liverpool, which sank off the coast of Anglesey in 1863.

Still one of my favourite typos: Dean Lomax & team are so immersed in their subject they're even starting to look like fossils…

Some beautiful Penrhyn slate in the @nhm-london.bsky.social evolution garden - with creatures & the excellent Earth science researcher who helped bring this real-rock timeline to life.

Look the the square window in the natural history #museum #evolution garden and what do you see?
A pterosaur!
As designed in 1875 and sculpted from terracotta to Alfred Waterhouse’s design.

#Tourmaline is probably my favourite #mineral.
It has so many varieties- like the lovely allochromatic Elbaite.
If copper-bearing, crystals can be a beautiful blue / green, like in this pegmatite.
