I think that a geochemical study of the surface minerals, a SEM and an
xray diffraction of the surface micas should show if the micas are
relatively fresh or not. A difference of nearly 1000 years should be
recognizeable.

As I understand it, this is more or less what Scott Wolters has done.
His conclusion is that the micas (biotite) on the carved surfaces of
the KRS are _much_ less fresh than on the equivalent surfaces of the
Hallowell tombstones.
