Pebble Spotting with Clive Mitchell
Ғылым және технология
Worn smooth by the sea, fitting snugly in the palm of your hand, the humble pebble is familiar yet so mysterious. BGS pebble-ologist, Clive Mitchell, shines a light on the shingle to work out what pebbles are made of and gives a few tips on finding the more exotic varieties.

Thank you for this video! My six year old daughter spent a very happy afternoon collecting pebbles on the beach yesterday, and we have spent an equally satisfying morning watching your talk and trying to identify them!
I feel I owe you thanks. After watching this I can see I have been taking everything for granite. Gneissly done.
I would like to see more of these, I love rock hounding

Your picture as a young boy, reminds me of Bam Bam from the Flintstones, he was always chasing down Pebbles.
This video was absolutely brilliant thanks
shared! may many kids become in love with geology!
Crinoid are the ones with holes, it was my first collection.
I'm convinced that the small quartz and agate are predominantly teeth and I am pursuing more information. I believe that it's quite possible that the two quarts pebbles you held were possibly also teeth.
Love listening to your talks thank you 🦪
I love looking for pebbles in any gravel drive. I bought some ballast year ago for the yard ad collect anything interesting. This afternoon I picked up what I thought was another pebble with a hole in it. Turned it over and there's another smaller pebble stuck firmly inside the hole!! Have you ever seen anything like that?
amersyth purple quartz which is a gemstone
I can recommend an interesting site inland, in the county of Cheshire on the edge of Cheshire plane . A place called Alderly Edge , near the town of Macclesfield. As you get to The Edge it drops away around 300ft at the top is exposed sand stone trapped in the sandstone are. ancient pebbles. The area was used for copper mining and the famous book weird stone of Brazingaman .
Could you please tell me why some pebbles are a different colour inside to outside,IE they have a different colour coat sometimes you can see this on chipped ones, health wealth and happiness

Hi there. The external surface of a pebble is exposed to the effects of the weather which can change the colour for example iron-rich pebbles can take on a rusty brown colour. Also in the process of being turned into a pebble the surface is continually knocking into other pebbles which gradually knocks off the rough edges and making the pebble smooth. This can also have the effect of making the surface appear a different colour to the inside. The classic example is a flint pebble which can have a white dusty exterior and a black glassy interior. Hope this helps!
Ps can you get opalised flint?? 🤔
Loads of gypsum seams west of Branscombe in the Triassic cliffs on the Jurassic Coast, but too soft to make pebbles
I discovered a 10 inch bellamite fossil on the beach, however it turned out to be a severn trent discharge. Can the water companies help geological discovery?
What is a Herkelmier diamond ?
In America we have places where you can go and buy some time and theees a mine they dig up or dig out place you can go mine there for a few the mine is own so your buying them but your also buying time spent looking for and adding to your tine vacation and collect
As per the q and a, I tried to bring a few pebbles home from Turkey and the airport security staff confiscated them all . Some sort of issue having them on board the aeroplane apparently.

Hi , I found a pebble on a beach in Cornwall and it looks unusual can you help ? - it has a hole in it and it’s looks like it’s been carved and shaped .

Its hole was probably made by a clam or crustacean several millions of years ago

PHD??? PERFECTLY HAPPY DELUDED !!!
I live in Amersham Chiltern Hills. If you dig down anyway about 1 cm can you find pebbles and sand as far as the eye can see that seems to go down quite far. So how on earth did the middle of England be made up of pebbles and sand. Personally my own theory is there has been many great resets and every now and then the world gets turned upside down and we’re not talking slowly. But then again I know nothing just guessing that’s why I’m watching this to learn.
Rocks Rock lol
I collect pebbles, to sell them and use money to build houses.

It becomes a stone at 14 lbs. I guess before that it is a rock.
