Congratulations Lucy, this is lovely news and well deserved - it is a very carefully considered and succinctly written paper

Escaped Dublin for fieldwork - Dani and Jack sampling Carboniferous volcanics on the Beara peninsula for Dani's PhD project.

Teach Earth - Free materials for teachers Teaching materials and resources for delivering Earth Science content across different UK school and college curricula.

Hello teacher friends! Annual call for anyone who might be interested in outreach activities relating to volcanology, hazards, risk etc to send me a DM or email. Also a quick plug for the ever growing stash of materials at earth-science.org.uk/teach-earth/

absolutely, may be a final year project lurking there.

The ‘gallery of interesting rocks’ is delightful, there really should be more of these

We're in Yellowknife (Northwest Territories, Canada) for the kimberlite conference. They like their geology here.

Reflected light view of vesicular tephra shards and the 25 micron laser spot size

Raw LA-ICP-MS data trace showing highs where tephra is ablated and dips where we hit vesicles

Its been a while since we last analysed tephra in the TCD laser ablation lab - look at these lovelies from an IODP core off Nova Scotia. The vesicles show as dips in counts in the raw data as we ablate through.

Its snowing! and I am a gleeful child for it. The TCD campus looks beautiful. To my PhD students - take the day off and enjoy while it lasts.

Thanks to @gernon.bsky.social for joining TCD Geology and the Irish Mantle Group for his talk on “Rift induced disruption of cratonic keels drives kimberlite volcanism”. Very interested in the drivers for, and magnitude of, evolution in the thickness and lateral extent of the cratonic lithosphere.

Congratulations to Dr Lucy Blennerhassett who passed her PhD viva today at TCD, it has been a pleasure working with you. Thanks also to examiners Gill Plunkett and Robbie Goodhue.

Some garnet peridotite appreciation for #ThinSectionThursday

We are trying to build a mantle research group in Ireland, many thanks to Nicolas Celli and Emma Chambers at DIAS for hosting our third meeting, on seismic tomography and state of the lithosphere. Next event - seminar by @gernon.bsky.social at TCD on 24th November

Our next 'ECR Skills for Geochemists' session will be on Mon 6th Nov @ 1pm. This session will discuss “...things I wish I knew when I started my PhD". This will be suitable for all PhD students, but particularly those just starting! Free sign up here: geochemistry.group/events/

VMSG 2024 workshops and post conference fieldtrip registrations now open - all the info is here vmsg.org.uk/events/vmsg2...
