That wouldn't be necessarily a component of a full Irish breakfast though!

I hear ya! It would help if I could import my work outlook calendar into my Google calendar, but as it stands, I can only go one direction, so have to look at the work calendar when I don't really want to!

When I open the museum here for the Galway Science & Tech festival exhibition, I do a 'Rocks & minerals of Minecraft' section (a few tables, & a treasure hunt around the displays). Every year I think it'll fall flat, but every year I get some kids REALLY liking it, giving feedback. It'll stay!

I have a copy of Emeleus & Preston's 1969 guidebook to the Tertiary Volcanic rocks of Ireland. I wonder how many of the sites are still accessible!

Here's the sample (loose on the beach) I have showing the ocellar texture (I'm using that term as I've used it for a granite) (2 photos) and one with a coarser 'pegmatite' (beach cobble).

thin slices are lovely - our local good pizzeria used to do an Irish breakfast one with sausage, potatoes, bacon, mushrooms (IIRC) and potatoes. I think I had them on a pizza in Italy too.

Haven't been in in a while, but the Roisin Dubh always expected people at gigs to behave, and it was great for that. Was unfortunate enough to be at an Imelda May gig at the Galway Arts Festival Big Top when she had to ask the crowd at the bar to quieten down. They ignored here. I was furious.

@rocksbydefault.bsky.social is the designer of the viewer. I can't take credit for it!

Have you seen the 'ocellar' type dolerite from Fair Head - olivine glomerocrysts with plag haloes? Spectacular. I've a slide of it here and tried to get a full thin section shot in XPL using my 'Viewing the Rock World' 3d printed viewer, a box and a bike light πŸ˜€

My 13yo is covering Consumer Affairs at school at the moment. Will I get her on your case?

It came up on my feed too and I was scratching my head about the headline. Still, I'll try to be positive and think that any geology news like this is good publicity and may be a 'gateway' to the topic.

Someone captured my colleagues an I servicing the cameras during KΔ«lauea’s episode 42. We stopped to discuss what we were seeing, but because I talk with my hands it looks like I’m fixing to push someone in…

I would LOVE to have a classroom that I could keep all my cool rocks instead of having them in my office and carrying them up and down three flights of stairs for practical sessions (no lifts-listed building, no access for wheelchair or people with limited mobility), but I do love the museum!

We're really lucky here (University of Galway) to have the original (1850s) geology and mineralogy museum still within our department. Teaching space is rubbish, but the museum is a gem (sorry!) There's a zoology museum too in a new building, original cabinets and displays though.

Oh, I would also use KROK-ido-LITE but I see from mindat.org that it's named from the Greek κροχυς which is pronounced 'kro-hees' approximately. Where does that leave us?

I actually found that it is mentioned in Terence Dolan's Dictionary of Hiberno-English. Thanks all, I'll have to start using it πŸ˜€

My mother was asking me this evening if I knew the origin of the term 'a pet day'. Her mother used it to describe a day of good weather in the middle of a lot of bad weather. Can anyone out there shed any light on this? It might be from Irish (my granny was of Tyrone stock) #speirgorm

And don't forget some body spray, deodorant, perfume - and a way to really irritate smell-sensitive people (I get watery eyes and a snuffly nose from a lot of perfumes, so it's miserable being stuck next to someone doused in scent.)

Oh I know all about that easterly air flow - it's making me pedal downhill on the way into work πŸ˜€ On the plus side, I get a good boost on the way home!

Meanwhile, on the west coast of Ireland, we've had LESS rain than normal in the past month. It's beginning to make me feel uneasy!

I (mis)read that initially as 'parasitic' amphibole. Seemed apt, for your 'poor garnet'

Got some photos today of samples I have. Two 6mm FOV for the foraminiferal sand, and a c45mm view of the lithothamnion maerl ('coral'). It's often coarser but the sample I have in work is a finer grained one.
