I thought I should come take a look at one of your videos since you're an actual geologist, not just some guy stumbling around on a beach looking for pretty stuff to polish up. I enjoyed the video. Thanks!
Flint ( Chert ) is one of my favourite rocks, it just fascinates me that something so perfectly glassy could have been formed chemically and appear so similar to Obsidian which is another of my favourites but which is quickly cooled magma. I would like to know more about Chert as you quickly mentioned open-cells/grains and left me wondering. I like what you say about rocks being pages in a book.
Chert is fascinating and can tell us a lot about ancient environments. It looks like obsidian and pitchstone because they have homogenous ingredients which gives them similar properties like conchoidal fracture.
I once went to an Art Gallery with the most amazing fossil full marble floor and instead of the paintings I found myself studying the stairs and floor on my hands a knees feeling quite ridiculous but practically unable to drag myself away, for a while at least.
I think that I know where that rock formation is in your musical intro at 1.15. It's at Porth Lleuog in Pembrokeshire, just around the Trwynhwrddyn headland at the north end of Whitesands Bay. You can get right up to those rocks at low tide which I do everytime I go there. I've just discovered your channel and stopped watching the first video I came across (What is granite?) in order to subscribe and start from the beginning of your videos so as not to miss any info.
What's the soundtrack? Also really enjoyed this - don't know anything about rocks, so learnt LOTS! It's amazing what you can tell about a rock and where it came from just from looking at it!
Yo I found this little pebble and it has a perfect line engraved all around it but does not connect and it’s magnetic. I should have a video of it on my channel.
Fascinating! My first guess is it looks like it could be magnetite and ilmenite rich basalt. But it could be lots of things and without being able to examine in person, or knowing the exact location it's from, it's difficult to say.
Hmmm, I'm going to say no as a rock needs to be solid and made of mineral crystals or mineral grains. Once it gets near the surface though, magma (lava once it reaches the surface) will have crystals forming or already formed in it, in which case you could start referring to it by it's primary composition e.g. a basaltic magma/lava, andesitic magma/lava etc.
As Gorl says, plate tectonics. When India colided with Asia, slices of bedrock were pushed up onto the land, some of those rocks were originally mud on the bottom of the sea, but now they are the top of a mountain chain.
I need someone to identify a rock of which nobody else today has been able to tell me what it is, can you I can send a picture inside and out of the rock. If you can give me a page to send it to
Yeah, you can send it to my facebook page, or I should have a contact email in my about page here. As well as clear pictures with a scale (like your hand or a coin) I need to know where you found the rock with as much detail as possible about the area.

Thanks! I started off stumbling on a beach, then did some stumbling at uni so I got a certificate. There's not much difference otherwise! :D
Awesome information. Thank you so much!! ❤
Excellent video, thanks.
Glad you liked it. I should probably do an updated version soon though.
Great first video, very excited to see the coming ones bae 😘!!
Thanks bae!

Brilliant work, Brooke. Very informative. Mind blown! I'll never look at a shopping centre floor the same way again!
Thank you! Be careful tho, I've walked into so many people! XD

Well spotted, that is exactly where it is from! Some of my favourite geology in Pembrokshire!
Sir, is basalt rock has a melting fusion?
We love you Brooke!!
Love you too bae
What's the soundtrack? Also really enjoyed this - don't know anything about rocks, so learnt LOTS! It's amazing what you can tell about a rock and where it came from just from looking at it!
Thanks! Music is just stuff I made to go with these videos.
Sir good day me I question what kind of rock is melting of an acetilen
I'm not sure what an acetilen is. Can you describe it and maybe I can help?

Could you put your social media links in the video description, Brooke?
will do
Why are there so many amazing minerals in that town? Was that a wall made of larvikite?? 😮
It's cos off the Uni has a lot of money. Yup, the supermarket is made of larvikite!
@@geologyjohnson7700 that's AMAZING 👏
Does molten rock count as a 3rd kind of rock with no crystals or grains?
Hmmm, I'm going to say no as a rock needs to be solid and made of mineral crystals or mineral grains.

So cool, congrats! I'm a graduate geology Master student, greetings from Italy
Thanks! Glad you are enjoying them. What is your masters project about?!
@@geologyjohnson7700 I'm studying georesources and geomaterials, very interesting!
And you? Are you doing a PhD?
Exciting! Yes, I am doing a PhD in precambrian sediments
How did marine fossils get on top of Mt Everest?

I have some cool rocks. I would love to show you. But alas, I am unable to share it in this post. Thank you
Thats a shame! thanks for sharing though!

There are only two types of rocks. Skippers and kerplunkers. Geology 101
We call them skimmers and spladooshers where I'm from. I also once got a spladooser to skim!
@@geologyjohnson7700 perfect description.
