Man, that Phyllite looks interesting but not familiar. I don’t think we’ve run across any of it that I know of. We decided to take the mystery piece and cut it on the saw when I’m feeling better. I went and grabbed it and looked at it with my wife earlier. The first thing I realized is it’s not light weight, as I thought for some reason. It’s actually similar in weight to an equal size piece of petrified wood. Not sure why I thought it was light. Must’ve been the color lol. Again, many thanks. I appreciate all of your input.

When we were rock hunting on the Llano river here in south-central Texas we found quite a few pieces of what looked like black/dark grey petrified wood, but it broke in half relatively easy and was dark all the way through, like below, with streaks of browns through it. Some of the pieces are considerably harder and I’m pretty sure when I tumble them the petrified wood I’m used to seeing will be underneath. Are these the opalized wood in process of turning perhaps? Maybe the process was stopped when it was uprooted or something? I thought it was slate that simply wore down until it looked similar to Wood. That is until I started finding the pieces that were much heavier and ‘tinked’ when hit together,

like hard rocks do.

These look more like a schist. Phyllite and schist that it forms in to can look a lot like petrified wood. I will post some examples.

Ok cool, thanks! Something new to research with my wife.Thing is, some are much heavier and more solid than the other ones. Like there’s much more developed rock underneath the black surface. I decided to put a couple of small pieces in the vibe to see what happens lol. One that’s black all the way through and another that’s more ‘solid’, like I mentioned above. I’m probably not explaining it very well (I’m sick and wobbly but still tumbling).
