Fig. 2: Deformation microstructures in serpentinites.
From: Ductile deformation during carbonation of serpentinized peridotite
a Foliated serpentinite with crystallographic preferred orientation (CPO) and aligned Fe-oxides tracing former polygonal, now flattened mesh cells (crossed polarized image (xpol) with 1λ-plate; sample OM20-13); b Serpentinite mylonite with strong CPO of lizardite and bastite porphyroclast, cut by a younger serpentine vein with anomalous extinction color (xpol with 1λ-plate). c Grain size reduction in shear bands (GSRZ), and deformation lamellae and kinking (red arrow in c) of larger serpentine grains (xpol). (b and c are both from sample BT1B_74-1_59-61). Scale bars: 200 µm.
