Thread: posible coticule, sharp change into an orange layer

Something that just occured to me, that stone looks as if it is from the hybrid, Les Lat layer. I have seen that color in parts of Les Lat stones.

Nice looking stone! There was a slate mine in Belgium with a couple of layers of coticule in Recht. They were only
exploited during a brief period. But the coloring looks very close to yours.

Man ! That looks good enough to eat !

That has to be a coticule, nice one. I have something similar on a coticule of mine but with a pink bottom layer.

What wood did you use for the scales?

In my humble opinion, and bear in mind that I am not the wold's foremost authority on identifying coticule layers, that stone sure looks like a Les Latnueses hybrid to me.
The stone second from left on the lower line in the photo is the "Burton Series 0001," A Les Latnueses, and quite possibly the most visually striking of any rock I've ever seen. It was sold, and I don't recall who now owns it, but I would dearly have loved to have bought it, if only to look at!

In any case, the OP's stone bears a strong resemblance ..

Sometimes you can get very strange colours from this layer.

thanks for your input!

the slurry it produced is milky, consistent with my other coticules

I do have a Les Latneuses coticule, mine doesn't have such exuberant colors but it could be posible, 1 thing is that my Les Latneuses has a realy hard hybrid layer and kind of a soft normal coticule layer, I haven't noticed this distinction while lapping this specimen.

The overall hardness resembles the la dressante layer (which I know can look exotic as well but not such a distinct layer transistion)

Martin, I do like your suggestion, looking at the back of my rock it seems to resemble this the most

@Piet, I honestly have to say that I don't realy know what type of wood that was, I bought a piece at the fijhouthandel in Arnhem in the section with wood for musical instruments, next time I'll ask
