Well, one problem is that stone comes in all the colors of the rainbow--hard to set just the one hue to it.
Secondly, with man-made objects, the stone used might not be native to the region where the construction is located.
Thus, a railway bridge of limestone might be built in an area whee chalk or shale is common.
But, that's just geology.
As ro just technique, I'd probably start with a base coat of lufrwaffe or horizon blue as a base. Over that would go a rather wet drywash of radome tan and unbleached linen. which would then be highlighted in Antique White and Sky Type S. Then a wash with burnt umber. This would probably benefit from pin washes galore.
For a more 'yellow' rock, I'd start with an umber base, then layer with ocher & yellow ocher with highlights of 'flesh' and ghost grey. The wash would be a purple-violet not quite black.
Hopefully that's worth more than 2¢
