Hi Tom and list Tom, slickensides (my books spell it differently than European books) are a feature on a rock face left by movement of rock against it. Sometimes its smooth, sometimes not. Most commonly seen at sites of traverse faulting where the rock on each side of a fault grind against each other. Its a geological term of which I'm sure you've seen too many already. A good book to have at your side sometimes if a dictionary of geological terms.
