Hi Jim Baxter,
And, that is what I am not seeing. I'am going to be a very hard sell on
the term slickensides until I see something that scientifically supports
it and why it is there. Do the threads actually appear and are they
threads??
In my mind, the coming apart part would not create a slickenside (cool
state) where as the coming together with great pressure and time would.
Just thinking out loud, not qualified to say one way or the other!
I also see where this appearance is shown lower in topography in it's
area which, to me, would be odd for slickenside.
Cheers!

Slickensides are polished surfaces caused by lateral movement along a
fault plane. In hand specimens they feel rough when you rub your
finger in one direction and smooth when you rub it in the other. Not
sure that test would be feasible on the size specimens most of us own.
In theory if the fault planes represent planes of weakness along which
breaks occur then you could be seeing both things - slickensides that
formed by lateral movement along the shock plane when the stone fractured.
