What type of data support the idea that shear zones grow in width as they accumulate displacement, and where would we look for the last increment of strain?
What will be an ideal response?
Answer: There is a positive correlation between shear zone thickness and displacement, indicating that shear zones grow in width as they accumulate displacement. This implies that the low-strain margins of the shear zone record the last part of the deformation history while the more central parts have been accumulating strain more or less during the entire history, although this does not always have to be the case.
