Viscous buckling of competent quartz veins within ductile schist under cyclic bulk strain, exhibiting axial planar cleavage refraction, conjugate Riedel shears, and en echelon tension gashes (褶皱与香肠构造共生动力学).
Under the terrace bed, competence contrasts turn simple compression into rhythmic necks and folding loops (褶轴偏转与颈缩并存). The competent quartz bands resist bulk strain until they pinch into lenticular chains, leaving conjugate tension gashes behind them. 矿脉在片理之间蜿蜒，像受压过甚的脊索。
Simulated non-linear strain partitioning between a stiff quartz ribbon and its ductile matrix (应变局域化与流变差异). Coupled Biot-Ramberg wavelength selection during shortening phases with localized necking along Riedel shear angles during orthogonal extension. The coexistence of ptygmatic buckling and boudinage stays stable across cyclic bulk strain; edge activity settled at 0.141 without blowing out character density.
