EBSD mapping of shear zones strain gradient - deformation mechanisms
Collected date : Mar 2018
Objective : characterize the deformation mechanisms and the crystallographic fabrics within homogeneously deformed granitic samples.
EBSD mapping of brittle shear zones precursors
Collected date : Apr 2017
Objective : microtextural characterization within a shear zone brittle precursor
EBSD mapping of shear zones strain gradient - seismic anisotropy
Collected date : from Feb 2019 to Jun 2019
Objective : calculate the crystallographic preferred orientation (CPO) of each mineral phase in order to rebuild the elastic properties of the polyminéralic aggregates.
