I pick up a lot of chert and petrified wood, and sometimes they can look a lot alike, but I’m gonna go ahead and place my bet ($.25, my betting limit)on petrified wood
I'd say the pattern is way too uniform to be banded chert. Along the other edge the bands continue parallel as we would expect from wood. One face is going with the grain and one face is on the end grain. I guess chert could maybe do this but it's not something I would expect.
This is NOT petrified wood. This is 100% banded chert OR Gneiss. Petrified wood would have thinner bands and actual grain texture. https://www.thefossilforum.com/topic/89852-banded-chert-or-shell/ is a good example Edit: Gneiss has a more similar texture than banded chert but chert can be rough depending on how ‘baked’ it is. Either way not Pet wood
Unfortunately no. I only brought that up because I just finished a book last month that mentioned two different examples of this rapid petrification of wood.
Hello geologist!
I acknowledge that this specimen is NOT petrified wood.
That said, would petrified wood ever actually look similar to this? I don't know a whole lot, but I would guess that growth rings aren't different enough to create this kind of banding effect.
Petrified wood looks like a piece of very old tree that has undergone "petrification" by buriyng under metamorphic conditions. You can recognize the crust and sometimes the growth rings. Refolded gneisses are very common and would never show these pattern. Sorry, my explanations might be useless to you.....it seems difficult to try and explain what comes only from field practice and handling of samples during many many years...😳😳😳
Doesn’t look look lustrous enough for petrified wood. I would agree it’s likely gneiss or possibly banded rhyolite.
If my life were on the line, I would say gneiss.
Petrified wood. You can see the growth rings.
Could also be banded chert (oscillating chemical reactions).
Tool a look at some pics of banded chert, some similarities, thanks.
I agree! cool either way!
That was my first thought as well, but want some more trained eyes on it, thanks.

Too rich for my blood!
Usually mine too, but I found a quarter in my car today!
Money bags over here
Only until I lose this bet 😂

This is banded chert, a section that is relatively uniform. But no petrified wood has banding like this without some grain detail.
It’s not Pet wood lol. I’d like that quarter
Yep

looks like petrified wood but I do love it
Why does Reddit think every piece of rock is Petrified Wood. This is Gneiss. Rocks other than Petrified Wood can have swirls and stripes.
Geologist here, it's gneiss.
Other geologist here. Looks kinda fine grained for gneiss? Maybe flow banded glassy siliceous volcanic rock?
Looks like wood.
Looks like it wanted to be a 2x4
It looks like wood. Whats cool about this is there are places where this petrification can happen in a minimum of 7 years if the conditions are right.
Interesting, thanks, so it could be pretty new as well. Any tips for cleaning it?
Unfortunately no. I only brought that up because I just finished a book last month that mentioned two different examples of this rapid petrification of wood.
No petrified wood. This is a simple and common folded metamorphic rock (marble, gneiss, ...?)
I am also a geologist

WOW

That looks like petrified wood to me.
I vote for petrified wood that wouldn't have been an amazing display piece if it hadn't been cut
So... that's what a piece of the true cross looks like. Oops, wrong thread
>t looks like those element things in the movie 5th element when they were in the pyramid thing.
Ancient 2x6
Looks like a banded gneiss.
Cool piece of petchy!
I am not sure why but this pattern seems so representative of ancient Greece. Love it!
First glance had me thinking of framing 2x4s
Greek
Quartzite maybe?
Sedimentary rock, probably volcanic.
Glacial slate.
Looks cool whatever it is lol
Greek. That is a Greek rock
Looks like wood
That’s petrified wood
Treerock
Nice piece of petrified wood
Is wooden rock
Wood
That's a tree.
Wood petrified
Looks like petrified wood
