How can we deal with pre-deformational fabrics, for example in conglomerate pebbles?
What will be an ideal response?
Answer: If all the objects (pebbles) had the same orientation before deformation we have a problem. We can only use the Rf/?-method if there are some pebbles that initially had orientations different from the majority of the clasts. We then have to rely on independent knowledge about the pre-deformational fabric, such as observation outside of a shear zone.
