Thin section and back-scattered electron images showing petrological characteristics of the Bellachat micaschist (AR736): (A) Main paragenesis of the sample with garnet and staurolite porphyroblasts in mica-plagioclase-quartz matrix. Sigmoids and tails around garnet highlight dextral kinematics. (B) Main paragenesis of the sample with dextral C-S structures corresponding to the S2 and C2 planar fabrics. (C and D) Inclusions in the outer part of garnet grains. (E) Partial replacement of biotite by chlorite and rutile inclusions in a plagioclase. (F) Optical differences between the dark staurolite core (St₁) and the bright staurolite zones (St₂). (G) Fractured staurolite core (St₁) with bright staurolite zone (St₂) in the fracture. Mineral abbreviations are from Warr (2021).
