Ho ho ho, Brian.
The rocks shown are, I believe, Lewisian Gneiss with red granitic
intrusions. Very much Pre-Cambrian - some recent work in that area has shown
the gneisses to be up to 3000 million years old, although I think this
gneiss is somewhat younger - if that term is applicable to rock 1700 million
years old.
Here's a professional analysis from close by Sandwood:

And you will immediately see the on-topic lens cap!
There's a couple more geological images in my Sutherland & Caithness
gallery.

There seems to be quite a bit of grain in those parts of your beach shots
nearest to the camera, Piers. (g) I wonder what would happen if you applied
Neat Image to them !!
A fine-grained film indeed.!
Were those exposed rocks of Cambrian or Pre-Cambrian age?
Takes me back to Geology 1 at Uni. (Which I enjoyed a lot).
