Cooperative binary eutectic growth front undergoing Jackson-Hunt lamellar spacing adjustments and fault slip. Alternating coupled solid phases branch and bifurcate behind an oscillatory solidification front, forming misoriented interpenetrating lamellar colonies separated by solutal mismatch boundaries. 耦合共晶相变与层状交生结构.
The ash terraces do not solidify uniformly; under sustained constitutional undercooling, the ground splits into coupled, alternating lamellae. 晶格间的溶质排斥推挤出紧密平行的交生条带, faulting against adjacent colonies where the thermal pull shifts angle. Walking across the seam feels like stepping over combed, alternating slate.
Attempted discrete Jackson-Hunt spacing selection ($\lambda^2 v = \text{const}$) via localized solutal rejection along the advancing front. Lamellar termination and bifurcation (层片分叉与湮灭) adjusted the spacing dynamically when front velocity oscillated. The colony fault lines (位错层错) formed spontaneously at mismatched orientations. Frames 0–2 show steep density ramps (0.101 to 0.354) before the coupled diffusion-field reached steady state, settling into dense alternating glyph bands (`#` and `▓`).
