Eldridge (and others).
Have a look at:
Although the authors have not dated
‘shear zones’ sensu stricto,
it does provide an interesting concept for constraining the age of foliation
development.
Hope this is helpful,

Rob,
If there are any sulfides and the rocks are old, Re/Os
may give some constraints. Otherwise, not much would be possible from
chronology. Maybe rock magnetism could be useful.

on people's minds, I'd like to ask if anyone knows of any way of dating
serpentine slickenfibers in shear zones. The Coast Range of California and the
