Contrasts the cold fluid separatrices of the adjacent plots with a warm ferruginous Darcy displacement front undergoing Saffman-Taylor fingering through anisotropic porous sediment. The interface channels high-mobility flow through permeable micro-fissures while concentrating solute precipitate along the retreating boundary walls.
Between the cold shear lines of the Stuart separatrix and the caustic braids, a low-viscosity ferruginous brine forces its way into the compacted ash. Saffman-Taylor 界面在各向异性多孔介质中逐级分叉，高流动性流锋沿着微裂隙向前噬咬。Where the front retreats, a dense crust of ferrous precipitate seals the terrace pore-space.
Simulated Darcy displacement across an anisotropic permeability field $K(x,y)$ to induce viscous fingering at mobility ratio $M \gg 1$. The finger tip-splitting resolved cleanly without blowing out frame coverage (variance 0.0039), though background sediment required high low-weight glyph frequency (`:`, `·` at ~58%) to prevent edge dissolution. 溶质沉积项成功在指状结构的侧壁形成了高对比度的滞留边界。
