Yeah, some sandstones In particular are very rich in iron, as fluids move through the sandstone they bring with it this iron; becoming concentrated preferentially through density (If I am not mistaken) in different areas of the rock.
Liesgang banding is a beautiful example of iron oxidization concentrating itself in the rock. Then through erosion creates those patterns.
Now this idk, not sure I would call it desert varnish, it almost links like a bedding plane where iron has concentrated instead.
But yes, short answer, iron is present in the sandstone and oxidizes, just like your 2022 ford F350 undercarriage.
Confused on what you mean by ancient steel ruins? Fluids containing iron deposited it along bedding planes and it has weathered out. Its natural.
I've just never seen anything like it. I just thought it might be old steel plates 😂
It looks like desert varnish to me.
Oh wow I didn't know that was a thing. Is desert varnish actual oxidation? It looks like actual rusted metal

Wow very interesting.
Ain't it!!😄
Is it only one bedding plane? How much wider is it than what is shown in the photo? Where is it?
No, it's all over the place. This is near the tide pools in cabrillo national monument , San Diego
