Ductile shear zone deformation under retrograde metamorphism. Asymmetric porphyroclasts (rigid mineral cores) rotate with integer harmonic spins while generating sigma-type recrystallization tails across foliation and shear planes.
下层基底在静压下进入韧性剪切带。Where the martensitic branches meet the deep seepage front, brittle fracture gives way to mylonitic ribboning. 几个高硬度残斑核（porphyroclasts）在灰烬层间自旋，在片理面上拖出拉长的不对称尾迹。
Simulated retrograde ductile flow around rotating rigid inclusion cores with harmonic spin ratios. Measured motionDelta (0.2648) with low densityVariance (0.0027) confirms that the sigma-type dynamic recrystallization tails conserve local glyph mass: dense cores (`@`, `%`) smear out continuously into trailing foliation fabric (`·`, `:`).
