OK Mystery stones

[fossis]

These stones are very numerous in SE OK, these are
just the ones i could carry home, I have seen them that
Wouldn't fit in a pick-up truck, (thousands of pounds),
& one had a perfect checker-board on it.
One lady had one that looked like a castle.
The explanation I heard is they are (concretions), the
softer sandstone wore away, leaving the harder, darker,
pattern's standing out.
I helped the late Gloria Farley look for carved stones,
& many people thought these were man carved, but all
are natural .

Cool! 8)
They look like Iron oxides.
Probably the'll make the rock harder, then the other sand stone. Could be true.

You're probably right,

WOW Those are really INTERESTING! SUCH cool shapes and forms there. I can understand the iron oxide thing... I've got a lot of iron around here on the Easter Shore, MD. And it's really stumped me. I can see that it's a 'natural' occurance, but at the same time, I see 'bubbles' (molten) and rocks/stones which have 'melted' into the iron(ish) slabs. I keep thinking--must have been a HUGE fire at some point-- enough to 'melt' irony bits in soil and form a 'whole piece'. I can see it in the layers of the erroded banks of the tidal river I'm on. And I've seen some interesting pieces. I just don't know what to make of it. And since you were showing pics of cool natural patterns-- I thought I'd hijack your post and ask about iron and how it behaves in the wild... I am used to irony soil- Virginia (used to live there) and points south have RED RED soil. Here it's mostly sand and clay-- and this irony stuff that falls in huge 'flakes' into the water. From some of the shapes I've seen, I've wondered if there might have been a huge camp-fire, but that doesn't seem logical. I've never seen a common (or uncommon) campfire which could melt iron in the soil to create a bowl shape or any recognisable shape at all. Could it have something to do with earthquakes and lava-heated spew? Any thoughts? (Fossis- I'm sorry I went on and on about somthing else, but it's related, and spurred my curiosity.)
Thanks for showing such unusual objects-- and offering an education to us all!

As said, the water also polishes (very slowly) if those iron oxides make it harder the water will need longer to break that down, and so patterns can get created.
I don't think earthquakes can do to much on stones unless teir in the earth so the earthquake can 'reach' them.

Even sand+wind can 'break down'/polish stuff if it's exposed to it long enough.

If I can get out to my river today, I'll show soem pics of what the swedes call "Myrmalm", some kind of Iron ore that can make/get cool patterns, often it's clean enough to be picked up by a detector! 8)

There is a dryed river bed in NW Arkansass that has something similar but they are IRON and will ring when hit with a hammer.
I was told that they were what was left from Radioactive lead silver deposits and the radioactive elements desolved everything but the iron.
The patterns are really unique.

I traded for some round, iron concretions, really heavy,
They came from a creek bed in NW AR.
They are about 3 inches thick, & look like a button, I will
post pic's tomorrow, 0r maybe the next day, .

You know Fossis... Those two look like fossilized dinosaur doo doo...

They do kinda resemble Coprilites, but most I have
seen, are very uniform in their pattern, The lady that
found these has large, medium, small, all shaped like a
button . (concretions)
Also these are dull inside, & copralites will take a
very nice polish.
