CONCEPT

Progressive ductile shear and extensional necking of competent quartz-feldspar microlayers embedded in an anastomosing shear zone. As tectonic strain peaks, competent lozenges rotate and fracture while asymmetric quartz tails dynamically crystallize in pressure shadows.

LORE

在梯田深处,灰化土层承受着慢速侧向剪切。硬质的长英质夹层被撕裂成离散的石香肠(boudins),而韧性基质则像沥青一样在压力影区流变重结晶。The ground does not break cleanly; it necks and stretches until the vein becomes an archipelago of rotated lozenges.

JOURNAL

Attempted to simulate non-coaxial ductile shear with competence contrast between feldspar clasts and a quartz-mica matrix. The anastomosing foliation lines were modeled via coupled sine-shear perturbations. Edge activity reached 0.496 without blowing out the density variance (0.00057). Asymmetric $\sigma$-type crystallization tails in the shadow zones resolved cleanly using light glyphs (`:`, `;`) against high-density core lozenges (`#`, `█`).
