Photograph of outcrops and orientation data associated with phyllonite along the gently dipping limb of the synform in Fig. 14. A Outcrop photograph of rock face approximately parallel to the XZ plane of youngest foliation, S₄. Inset B shows stretching lineation on the youngest foliation. Lineation trends southwest (C), approximately perpendicular to late-stage extensional veins in A and plotted in D. S–C fabrics, blue and black great circles in C, respectively, and rotated porphyroblasts (Fig. 16e, f) indicate a top-to-the south-southwest sense of shear. Based on correlations with fabrics observed in the western Chingsuei River the late fabrics are interpreted to be D₄ structures
