Could this potentially be petrified wood? Found near the tablelands western newfoundland

Found in a large stream bed. It did not resemble any other rock/mineral in the nearby area.

Doesn't appear to be petrified wood. It looks geologic.

I agree - not a fossil.

Looks like a quartz vein.

I'm not an expert on rocks or your area, so take this with a grain of salt.  But it looks similar to pictures of calcium carbonate veins in travertine to me.

I don't know about the western side, but the eastern shore is Ediacaran, with ash layers in the beds.
