Highlight of my Lisbon trip, visiting the Carmo Archaeological Museum. This 14th century gothic Church is in incredible condition for the fact it survived the 1755 earthquake that flattened most of the city
#Lisbon

Had the pleasure of roaming the streets of Lisbon a couple weeks ago and everywhere I looked I saw this cool limestone. So many of the buildings and pavements are made of this gorgeous stuff!

This is a sign of welding. Found in ignimbrites, material has been deformed and stretched by the hot fast PDCs of the past. This one here is from Kintyre, Scotland.

What you're looking at is lava... Lava in Scotland. The way the rocks look like they are bending is called flow banding which shows the direction the lava was going before it cooled into rock 🪨🌋

Moment of appreciation for this intraformationally folded siltstone with galena and interlayered sphalerite from Mount Isa, Queensland, Australia 👏👏

Thanks to my brother for letting me run wild in our local rock shop for my birthday/graduation. Check him out on Instagram for some cool object conservation content! @jwq_conservation

Rocks can be dangerous without the help of volcanoes or landslides...

Check out my new reel on Instagram, I tried my luck at some digging for gold 🪨⛏️

What a gorgeous specimen of a pallasite meteorite. The olivine rich crystals pop against the iron matrix. So interesting that olivine is too soft for jewelery but pallasite is a wonderful way to incorporate such a fascinating gem into your bling ✨

This week marks the University of Glasgow's 574th birthday. As the fourth oldest university in the English speaking world and an objectively beautiful building, the gorgeous locally sourced Carboniferous sandstone bricks are a staple of the city skyline.

I've been doing fieldwork for my dissertation and thought I'd share a feature I kept coming across: accretionary clasts. Like accretionary lapilli, during an eruption high moisture content in the air can make ash clump together, here the ash has used clasts of broken lithology as nuclei

Garnet is so cool - well actually it can be evidence of hot, high pressure environments or fluid activity. With its red square ish crystals, it's an easy one to identify and impress your friends on your next hike
