Amphibole reaction rims record shear during magma ascent - Nature Communications In this study, authors investigate what happens to magma before a volcanic eruption. They find that crystals react to magma flow before it reaches the surface, preserving a mechanical fingerprint of t...

When crystals start to move: uncovering the hidden role of shear during magma ascent What if volcanic crystals don’t just record chemistry, but motion? Using crystallographic analysis, we show amphibole reaction rims capture magma flow prior to an eruption: crystals grow aligned, then rotate with shear, revealing a hidden mechanical fingerprint and record of magma ascent dynamics.

12 years ago today, I began my BSc #geology mapping project on the Isle of Kerrera, Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿. Now, I’m walking the West Highland Way, reminiscing on how it all began
