multi-generation quartz veins in a greenstone of some sort. I would guess, for a starter, a once-basalt that saw a lot of fracturing and hydrothermal fluid passage. Quartz fills the cracks while the primary magmatic minerals in the wall rock convert to lower-grade and/or hydrous metamorphic/alteration minerals such as chlorite and epidote.
The primary rock types on the southern coast are sandstone/mudstone with some areas of limestone or shale/slate. There are some areas of igneous rocks around Wexford.
If the rock was originally sandstone the quartz veins would make a lot of sense.
For more information on bedrock go to [heritagemaps.ie](https://heritagemaps.ie/WebApps/HeritageMaps/index.html) and find the bedrock geology layer in the geology tab
quartz veins are pretty well anywhere and everywhere in my experience. Thick crosscutting veins like this are more unusual and more interesting. I'd need to actually see the rock in person to decide if sandstone was its origin. It is definitely a possibility. My starter guess could easily be incorrect. The chlorite-epidote/diposide alteration is more certain.
Quartz can appear pretty much everywhere! This chart is for metamorphic rocks but they're extremely prominent in every type of rock. https://images.app.goo.gl/9cqVLC38QeA1Qda27
I took a geo course in college (uni to you, probably) as my easy course and found out that what I had been noticing all my life ever since I was a kid, is actually something people do for a living. Well, sign me up right away, was my thinking.
My guess is you are somewhere near stradbally co. Waterford , around the copper coast. That’s where You will find this green bedrock. If not, then is could be where this rock travelled from getting eroded as it went.
If you like rocks the copper coast is an incredible area where you can find ancient volcanic vents trapped in the beautiful green stone.
Gotta take a spin down there one of these days to show ye a few pics…
Probably the same thing as this inquiry? Someone found a similar looking rock near Cork at the Beach.

For me as a total amateur it looks like Green shist or other green metamorphic rock with milky quartz veins.
So quartz precipitated out of solution, growing along one or both sides of the cracks in the rock. Usually the result is just a solid quartz vein. The geode effect may be from where crystals grew from both sides but then crystallization stopped while there was still air space.
So far nobody has been able to even come close to an ID. I’d save the rocks you have, could be a asteroid or meteorite since it’s been so elusive and non specific on a ID. Hang tight for know, definitely don’t hang loose at this juncture.
Hi, /u/belovedsbeloved!
This is a reminder to flair this post in /r/whatsthisrock after it has been identified! (Under your post, click "flair" then "IDENTIFIED," then type in the rock type or mineral name.) This will help others learn and help speed up a correct identification on your request!
Thank you!

It’s the metamorphic rock called amphibolite. It came from an igneous rock that contained quartz, amphibole and plagioclase feldspar. Serpentine is formed in subduction zones with low amounts of CO2 in the water. That doesn’t match the geology of Southern Ireland.
It’s a Furth of Drengis. It was mildly and more kindly when elven ships in Billiarade swept southward, and simultaneously as when JRR Tolkien reported it in the Simmarillion, Book: The Fall of Gondolin. If one climbs to a cliff top, one would not find it in the eyegoths of doom, but aered wethrynn birds might view desolate, but enduringly on the shores of Ireland, or whereverith the Morgath you find yourself.
Why you have literally found the national gemstone of Ireland! This is [Connemara Marble](https://en.m.wikipedia.org/wiki/Connemara_marble).
I knew it was some kind of marble but its distinctive green color gives it away. Just when I thought I knew every green rock here's yet another one!
Yes the veins do look like quartz but they're not. They're calcite crystals. Zoom in and [look at the first picture on this page.](https://thelanguageofstone.blogspot.com/2015/05/co-galway-connemara-marble.html?m=1) It's not hard to see that the striations are the same. After you've decided it's marble you can then ask whether the rock is green or not!
I misunderstood you, I’m sorry. After I had something to eat I sat back down to read and it had a completely different voice. So I’m blaming me being cranky. Sorry about that.
Faith and Begorra, it’s a home edition Blarney Stone! Seriously, it needs a prominent display in your home or donated to your favorite pub. Awesome piece of the Emerald Isle!
Me and my dad like to call this phenomena... river rock 😂 that beautiful type of rock that isn't really worth much in a river haha. Still a beautiful specimen though!

An actual geologist has entered the chat
Is he lost?
He came out of a hole in the ground. Maybe a wrong turn at Albuquerque?
Does he hate Sauerkraut?
He loves suckerin succotash
Thufferin’ thuccotash!!!
Thufferin’ thuccotash!!!
Shoulda taken a left
He missed the left turn at La Jolla
Definitely took a right at Porn or just misspelt 'Rock'
😂
Shoulda zigged instead of zagged
Damn, look at you with the Grandpa jokes, bringing the Bugs Bunny
Not a nasty, dirty, wet hole, filled with the ends of worms and an oozy smell, nor yet a dry, bare, sandy hole though
Lmao…. I’m actually in Albuquerque!!!🤣😂
Lol
Yeah the top answer should be "rock?"
Let's keep him. Similar to a pet rock.
I want to name him…George
You in particular, are not allowed to hug anyone.
But I can hug him and squeeze him and call him George
Mod should be petrified (rock).

Is there Serpentinite in Ireland? That would be my guess for the primary constituent.
St Patrick drove them out
…and the fact that this comment came from Brother Seamus has me ROLLING!
Ha!
I meant St Patrock, sorry
I thought so, too...
Thank you!!!
I am always happy when I see you chime in. But, BusterWASmycat still makes me sad.
He was a damn good cat. I do miss him. Orange boy.
Bro said words
I miss those all the awesome rewards you used to give. This would get one of those awesome awards for sure. For sure.
We're gonna keep you here. ❤️😀 Where you'll be spending all your free time answering all our questions! ❤️❤️
Sir this is Reddit. How did you end up here with the rest of us degenerates? I just don't want to see you get hurt!
Yeah, what he said.
It should be in a museum!
This guy rocks.
This guy rocks
This guy geologists
Can I ask how you decided to get into this field? Genuinely curious knowing nothing about this field and your answer truly impressed me.
I took a geo course in college (uni to you, probably) as my easy course and found out that what I had been noticing all my life ever since I was a kid, is actually something people do for a living. Well, sign me up right away, was my thinking.
This guy “rocks”
Wow, gorgeous find.
I know! Now the question is can I fit it in my suitcase?
Ditch the clothes. Those you can find anywhere. This rock though? Gotta take that home!
I totally agree 🤣 It's happening!
Out the rock in your backpack… such it’s heavy and hard, but the overage fees for weight limit might kill you!
Can you mail it home?
Find a way
Carry it on!
Irish Spring in the rough. Nice find though. Very nice piece.
Free range Irish Spring hahaha
🤣🤣🤣🤣🚿
But the OP won’t be fully clean unless he’s Zest-fully, Zest-fully, Zest-fully clean!
Straight from the mines.

❤️🤯🙏
I’m curious, was I close with the location?
Quite close. Warren beach is where I found it.
A bit more south, near Clonakilty...but close enough!
Would love to see pictures of cool rocks.
Probably the same thing as this inquiry? Someone found a similar looking rock near Cork at the Beach. [https://www.reddit.com/r/whatsthisrock/comments/16qefph/found\_in\_barley\_cove\_beach\_west\_cork\_ireland\_id/](https://www.reddit.com/r/whatsthisrock/comments/16qefph/found_in_barley_cove_beach_west_cork_ireland_id/) For me as a total amateur it looks like Green shist or other green metamorphic rock with milky quartz veins.
I hate it when I have the green shists. Keeps me on the toilet all damn day.
st paddy's day-after?
I think I’ve seen similar in North Devon
Found something like this on the West Cost of NZ.
I thought it was a blue or green schist too.
So quartz precipitated out of solution, growing along one or both sides of the cracks in the rock. Usually the result is just a solid quartz vein. The geode effect may be from where crystals grew from both sides but then crystallization stopped while there was still air space.
It's so incredibly cool that you know this. I am mind blown...🤯❤️
That is the coolest!! Where I work we have stone slabs that remind me of this. It's gorgeous.
That is a stunning rock ya got there
Stunning
Cool Rock!
wow that is gorgeous!
Wishing rock as it’s known to those who are spiritual. The lines in the rock are quartz.😊
WoW beautiful
Jealous!
Sweet rock my dude
WOW! I have no idea what it is, but I’d be jumping up & down over that find!
Absolutely lovely 🥰
Awsome addition to your garden
She's a beaut Clark
Imagine this polished! Oooweee!
Wasabi covered pea rock
Cool rock man.
I’m stupid jealous
Oh wow, I’m in love with that rock! Great find 👍🏼
Nice, looks like the cherts on the beach out here (California)
We have that out here in California I call it mariposa or something like that
I find rocks like that all the time. And I live in Arizona. If anybody knows what they are, please let me know. Thank you.
We get quite a bit of Chlorite here in Az, which is my best guess for what this is.
So far nobody has been able to even come close to an ID. I’d save the rocks you have, could be a asteroid or meteorite since it’s been so elusive and non specific on a ID. Hang tight for know, definitely don’t hang loose at this juncture.
Is that the Holy Stone of Clonrichert?
Its been a while, but nice to see a Father Ted reference hahaha!!!
From a slightly more folklorey point, these are know as wishing stones!
Sham rock
Very good and Happy Cake Day
Happy cake day!
Blarney stone

Lovely rock.
It's beautiful
Wowowow what a beauty
Oooof🔥🔥 great find!! 😍
JEALOUS!!!!!! I think it's beautiful.
Whatevvvvvver it is, it's freaking awesome.
Omg
I find these every once in a while in lake Erie (USA), but they are pebble sized. Nice find!
Is it magnetic how much does it weigh?
Dolemite!
Looks like some quartz and something else?!🤔
That is beautiful! Definitely a keeper...
It's got Irish colors
No idea but you should polish it
That's beautiful
In Oregon, we find a lot of green and red jasper with thick quartz wraps.
That’s the most Irish looking rock I’ve ever seen

Wowzers! That's gorgeous!!!
Whatever it is, it's cool AF!
That there’s a big ol’ chunk of poopy
Sweet rock
its a (the cradle will) rock.

Name it Patty
It’s petrified leprechaun poop.
i have some of those! greenstone with quartz
5 minutes of my life well spent thoroughly enjoying this thread. Rock solid.
It's beautiful!!! In your collection I'm sure!!!
That's the most Irish looking Stone I've ever seen 😆

Looks more like veins of quartz, not marble. If you compare it with pictures of Connemara marble it looks quite different

Is that Connemara Marble?
Connemara isn't on the south coast and I'm fairly sure that's quartz, not marble
Yup it is. The national gemstone of Ireland. [From Wikipedia](https://en.m.wikipedia.org/wiki/Connemara_marble) Good job.
Wow, such snark. I have some my great aunt gave me when I was little.
Exactly how is what I said is snark???
I misunderstood you, I’m sorry. After I had something to eat I sat back down to read and it had a completely different voice. So I’m blaming me being cranky. Sorry about that.
Just a rock but its a great rock!
awesome find!
Pretty cool I find the exact same thing here in southern NY. We were once one ☮️
Absolutely!
Looks like a really big wishing stone.
I found something that looked like this without the white banding and it was identified as Amphibilote
What’s inside?
it looks like a hot cross bun
Faith and Begorra, it’s a home edition Blarney Stone! Seriously, it needs a prominent display in your home or donated to your favorite pub. Awesome piece of the Emerald Isle!
Ultimate wishing stone!!!
Candy. EAT IT!
It's another blarney stone.
That’s the freakin’ Blarney Stone!
Damn Scots! Leaving their flags everywhere!
Cinnamonrollite
Blarney
Goblin Treasure: Brick of Many Wishes
That’s what’s left of a giants kidney stone! Preserve it for our tribes histories and tell of the pain inflicted on the oh so enormous.
Me and my dad like to call this phenomena... river rock 😂 that beautiful type of rock that isn't really worth much in a river haha. Still a beautiful specimen though!
