Here are my questions and answers related to your presentation 

 

 

 

Q#1: What are large magnitudes of shear-wave splitting and orientations of fast polarization parallel to the Alpine fault show?

 

A#1: Large magnitudes of shear-wave splitting and orientations of fast polarization parallel to the Alpine fault show that pervasive simple shear of the mantle lithosphere has accommodated the cumulative strike-slip plate motion.

 HAB: I agree.

 

 

Q#2: What happen for oceanic lithosphere when we have much greater creep strength of olivine than of crustal minerals?

 

A#2: It makes oceanic lithosphere strong in the depth range where continental lithosphere appears to be weakest.

HAB: I agree.

 

 

 

Q#3: What are the two processes that can align anisotropic minerals?

 

A#3: (1) rotation of crystals in a finite strain field and (2) dynamic recrystallization.

HAB: I agree.
