The second was a rock-on-rock where the upper rock had some elongated black crystals in it.
Both these examples are so noticeable, I cannot imagine them not being used quite deliberately.

Some geology examples from Stirling
While exploring around in Stirling, as described in my previous post, I came across a couple of examples of use of a rock with some kind of special characteristic. One was a split-wedged rock that had a granite wedge that was covered with reflective micah.
The second was a rock-on-rock where the upper rock had some elongated black crystals in it.
Both these examples are so noticeable, I cannot imagine them not being used quite deliberately.

[Noticed that last comment at a (much?) later date] Do you think you could leave some clue about who you are so I could answer your question?
