MrsMastiles: "Ready when you are MrMastiles"

I was going to go with something that included the phrase 'fanny lion' but thought that might be taking it a bit too far.

Is that a permanent stoop from pushing the pram or are you very short?

/geologist mode on/

Even with my glasses on I can't see at that distance. Does it fizz with acid? Are there any fossils in it? If you scrape it with a knife does the stone or the knife get marked? Any structure other than the dimples we can see? Where do you live roughly? Which will give us an idea assuming the stone is local.

I don't understand, there doesn't seem to be a bicycle in this picture of a back garden.

Stand Aside Mortals.
Geologist coming through!

Doesnt look like limestone from here, but then a photo isn't ideal.

put some (a drop) of vinegar on it.
if it fizzes, it is Limestone of some sort (or at least calcitic)
if not, it looks like sandstone/gritstone to me.
where are you?
stone like that is ALWAYS local. (unless your the chump at one of our sites who insisted on importing welsh slate to clad a house in portishead. Looks crap as its totally out of place, and was heinously expensive...anyhoo, i digress.

look up your location on the "BGS Geoindex: Onshore"
and it will tell you what your local bedrock is.
its almost certainly that.

Cement rendering made to look like coping stones.

Do you know the property or did you just stop and take a photo as you were cycling by? 😆

Some geologists use a series of observations to reach a logical conclusion. Some you'll note make rash assumptions. This is why a mountain of baryte appeared as quartzite on the geological map for many years.

Where are you? The limestone suggestion could be a wild guess, as it's not easy to carve. Can you do a better pic, as close as you can. Meanwhile I'll bet on a Pennine sandstone.

Unless they're cast, do they have repeating patterns, block to block?

PS I'll bet the Barite isn't there now.

Hi I would say sandstone, don't think it's gritstone because you would see more large grit particles on the surface from the weathering. I would also say you could rule out limestone it doesn't green as easy with weathering. Is it solid at the end or is it mortar they may be old ridges from a roof not coping stones. 😀

The fractures in the right and left hand blocks are typical of millstone grit though. The lower milstone grit contains lots of "crystals" but as it grades up into calcareous sandstone they are rarer. Upper millstone grit would be my best guess just using the photo.

This.

Or at least, it's they cement and crushed rock that they use for making garden bits and pieces. I bet that if you look closely you will find two stones the same.

It is definitely not cast (100% certain it is natural) - and we are in Harrogate and the wall is approx 110 years old.

Why are you so sure it's natural stone btw?

Because it is clear it has been hand-shaped close up. I would be very surprised if I was wrong on that.

Well what they normally do with those cast stones is have a mason make them by hand then make the mould from that.

Not disagreeing with you, it's hard to from the pic and if it's as old as that it's unlikely - but if I were you I'd just to a quick check for similarities 🙂

Definitely that age too - the house was built in 1899/1901ish and it's all original as it is part of a terrace all with the same spec wall.

Thats sandstone. Loads of the places round my neck of the woods are made of carboniferous limestone.

The heavily weathered victorian sea defence walls look just like that.

Harrogate it is 95% likely to be millstone grit

Coarse Arkose Sandstone. AKA Milstone grit. If not, I'll eat my hat.
