#AskAGeoscientist! 🪨⚒️🌍🧪👩‍🔬 Ever wanted to ask what it's like to walk on lava? How we know what a volcano plumbing system is like? Do volcanologists actually wear those silver suits? Whatever your burning question, pop it below as Friday I'm recording a podcast with @smitchellscience.bsky.social!

Day Five (the final day!): On our final day we visited Egerszalók caves where we learnt and discussed about geo-cultural heritage. This gave us an insight into how ignimbrite material allowed people to move into caves as homes.

IAVCEI Commission on Volcanic Sediments @comvolcseds.bsky.social · 11/04/2025

Day Four: Today we explored the Demjén ignimbrite from east to west. First we saw it outcropped in a quarry with some fantastic elutriation pipes

Day 3: We started off the morning with a bonus stop to look at some lovely submarine deposited accretionary lapilli. Check out the beautiful cored acclaps with a pumice centre 🌋

Day 2: Today we travelled north into Slovakia 🇸🇰 where we observed a basaltic diatreme section and had lots of discussions surrounding maar formation and infill Then we explored a tuff ring with a castle on top! Look at those baked clasts 🌋😍

A group of geologists standing in front of a large (~20 x 12 m) outcrop. The outcrop is beige and grey. On closer inspection the lower ~4 m consists of interbedded layers of lapilli and tuff. These layers are interpreted as maar scoria layers. Above this are two distinct massive units that contain large sandstone clasts with evidence of imbrication.

Day One: Today on our field trip we visited Sámsonháza and saw this amazing outcrop! We looked at the contact between andesitic sills, volcaniclastics, and peperite 🌋 Lots of good rock chats and some great local food! Bring on day 2!

Good morning Budapest! Am excited for the @comvolcseds.bsky.social field workshop around Hungary looking at volcaniclastics and sedimentary successions.

Photograph of the Parliament building at sunrise. The building is spectacular, extravagant style. It is mirrored in the waters of the Danube River. An orange sky gives the photograph a warm glow. It was not warm.
