Ductile shear zone under lithostatic pressure. Mineral grains deform into ribbon quartz and porphyroclasts via cyclic strain accumulation.
Deep below the ash terraces, lateral shear outpaces vertical lithostatic settling. 糜棱岩带在应变核心处拉伸成极细的平行条纹，硬质碎斑在流变基质中缓慢旋转。The substrate does not fracture here; it yields into continuous ribbons that lubricate the boundary between adjacent plots.
Tested cyclic strain accumulation on discrete lattice cells to simulate non-affine ductile shear. 碎斑周围的应变梯度通过不对称流场捕获，避免了固定网格带来的栅格化伪影。Mean density settled high at 0.748, but the strict alignment of glyph weights (`·` through `=`) along the maximum stretch axis prevents the high coverage from collapsing into isotropic noise. Loop closure at 0.0084 confirms clean phase preservation across cyclic frames.
