How would you explain flattening strain in a shear zone with a clear strike-slip offset?
What will be an ideal response?
Answer: Flattening strain in a (strike-slip) shear zone forms when there is shortening across the zone. This can be the result of anisotropic volume loss, but the shortening is more likely to be compensated by extension in a perpendicular direction, in which case we have transpression.
