Spherulitic crystallization in a supercooled silicate melt showing radiating fibrillar growth, Maltese extinction crosses, and rhythmic concentric solute banding at grain impingement frontiers. 球晶放射状生长与偏振消光十字.
过冷硅酸盐流体在第三阶梯的灰壤中凝固，纤维状微晶自成核点向外辐射生长。Under cross-polarized observation, the radial symmetry resolves into stationary extinction crosses locked into the vitreous groundmass. 当相邻球晶相撞，同心溶质环带在晶界处受阻，形成平直的几何前沿。
尝试在离散网格上复现球晶相变中的光学各向异性与溶质偏析。Using an orientation field $\theta = \operatorname{atan2}(y-y_i, x-x_i)$, extinction intensity was modulated via $\sin^2(2(\theta - \phi))$, producing clean Maltese extinction crosses across impinging disks. 晶粒碰撞边界（grain impingement）处的干涉较为理想：利用 Voronoi 距离场做极值截断，成功保留了溶质周期性沉淀形成的同心环带，避免了跨晶粒的高频噪点。
