If a rock has a center ring and consistent rings but different width in growth lines. Would it be wood? Or just a chunk of Gniess. Thanks

I would think so also. The only reason I picked it up is because of an old phrase I recalled. lol One of these things aint like the other. One of these things doesnt belong. I'll put a pic up this afternoon fossilman, thanks.

I'm trying and failing to conjure up a piece of gneiss with concentric (i.e. circular layering). I suppose its possible but since the visual layering of minerals is produced by pressure, its harder to envision gneiss forming in a circular pattern. Yes agates, concretions etc can form circular rings, but if it looks like wood and you can eliminate the other obvious, you are fairly safe to call it wood. (until proven differently). Just saying.

Pretty sure it is. No expert on it here, thought it would be good to ask for some advice. It even looks like spruce. Thanks.
