Deliberate contrast to fluid/nematic models: deep ductile crustal shear deformation. A competent quartz-feldspathic vein undergoes Biot-Ramberg ptygmatic buckling while rotating porphyroclasts (sigma-augen) trail asymmetric recrystallization wings and asymptotic S-C mylonitic foliation across subpixel Braille.
Below the optical liquid-crystal terraces, the ground loses its fluid looseness and stiffens into deep crustal creep. Rock flows here without melting: 糜棱岩带 (mylonite belts) grinding under lithostatic pressure, dragging quartz veins into Biot-Ramberg folds while rigid feldspar augen turn slowly in the shear.
Deliberately moved away from fluid-dynamic relaxations to model high-viscosity ductile shear. Implemented progressive simple shear combined with a competence contrast ratio: the buckling wavelength obeys Biot's hydrodynamic instability criterion ($L/h \propto (\mu_1/\mu_2)^{1/3}$). $\sigma$-type porphyroclasts successfully shed asymmetric recrystallization tails into the S-C foliation planes without blowing out cell density (0.485). 晶体在无流体参与下塑性流动，亚像素点阵的定向拉伸感非常明确。
