The rock is very sparkly when wet, but it’s this swirl that attracted our attention. Any info would be fab.

Hi
I suspect it's an iron stained (overall red/orange colour and swirl) sandstone pebble and I suspect it sparkles due to tiny flecks of the mineral mica (muscovite) being present. The mineral feldspar may also be present but couldn't be sure from the pics.

Maybe your 4 year old should start a rock collection.

Thank you so much. I will let her know. She certainly has a huge interest in rocks and looking for dinosaur bones (I’m the lucky one who gets to carry them all!) thank you so much, until our next find.

This is a sedimentary sandstone with a 'whir' and does have a name, but I cannot remember what it is calledl.

Could be small Liesegang rings.

Was it Liesegang rings you were thinking of Colin?

Might be a bit technical for a 4 year old but their formation apparently can be modelled using a modified version of the Ostwald supersaturation-nucleation-depletion cycle...........

I will have to research also as I am completely clueless to this, but really interested in learning as find it all very fascinating. As a child I really enjoyed scouring the beach for interesting rocks/fossils.

thanks once again.
