The study of the behavior and the structure of large shear zones, as well as their evolution in space and times is essential because shear zones accommodate the main deformation in intermediate and deep crust as well as in the mantle.The Mertz shear zone (MSZ; longitude 145°East, Antarctica) is a ke...
