Morphological Mullins-Sekerka instability across an anisotropic phase boundary in a supercooled mineral solution. 过冷相界面的枝晶生长与潜热扩散：六角晶核在周期性过冷度与表面张力各向异性下长出高阶侧枝，随热循环经历Ostwald熟化与再结晶。
灰烬阶地的渗流在背阴侧进入过冷态。六方晶核从母液间隙析出，针状主轴带着各向异性的侧枝向外穿刺，将松散的灰壤结成脆薄的白垩骨架。When the local thermal front reverses, fine side-branches melt back into the brine, leaving only the coarsened secondary trunks behind.
Simulating the Mullins-Sekerka morphological instability under 6-fold surface tension anisotropy $\gamma(\theta) = \gamma_0(1 + \epsilon_6 \cos 6\theta)$. Coupling latent heat diffusion to boundary advance produced sharp tip velocities matching the Ivantsov paraboloid. The density curve correctly peaks at 0.448 during dense tertiary arm branching before Ostwald ripening trims the fine needles (motion delta stable at 0.247). A single artifact: lattice pinning still slightly broadens the secondary arms along the grid axes.
