Calvert Cliff Iron replaces wood?

Recommended Posts

I found this yesterday at Matoaka, looks like wood but it is preserved (or dare I say petrified) in iron. Is it wood or geological? Has anyone found something like this at the cliffs before?

Below are pictures of a large petrified wood piece from the Miocene of Virginia for comparison.  I find lots of small pieces of wood preserved in the Pleistocene bog iron of Virginia that look very similar to your specimen.   But it is always difficult to tell for sure from pictures.

 

Edit:  I should be able to take a few pictures of the bog iron wood within a day or so.

Not seeing wood here, but pictures of the ends may change that opinion.

It’s hard to get a good picture of it, somehow looks more wood like in real life. I’ll get a end pic for ya soon.

That material looks like some of the small pieces of jet I’ve found. I am used to finding lignite from the Miocene, but have never seen it in iron (assuming it’s from the Miocene). I have seen similar in the Cretaceous but of course that never exposes on the cliffs. Thanks for the photos!

As promised, pictures of three pieces of petrified wood in bog iron from the Pleistocene of Virginia to compare your specimen to.  I had larger pieces that better showed the wood grain patterns and rings but I donated them.  I have probably a hundred or so smaller pieces.

Here @ynot, doesn’t show much.

Thank you! Looks similar, though it’s in a finer grained rock. I don’t know what age mine would be, either Miocene or some overlying unit.

Does not look like wood to Me, I stick with an iron concretion.

Agreed. Maybe more of a slicken side sort of thing to some extent.

Seeing the end view of your specimen, I now think it is an iron concretion.  You can see the wood in the end view of my specimens and a little of the bog iron.  I can only see the iron in the end view of your specimen.

It reminds me of Palmoxylon, but I'm not sure on the ID.

What I did with my pyrite replaced wood was expose the grain of the ends by using a rough file and finishing with some finer files. That told the tale.

this looks like an impression of wood in bog iron with perhaps some adhering. I have some like that from the Deep Cut at C&D. Could have been a lignified piece with lots of cavities that were infiltrated with the iron. Haven't seen any straight up bog iron with that ribbed look but ya'll have no doubt seen more of it than I.

I tried to compare it with the specimen from here . :)
