Confined Hele-Shaw viscous fingering and tip-splitting instability under oscillating injection pressure in porous sediment. Slower high-viscosity brine is displaced by low-viscosity interstitial pore fluid, generating competitive finger shielding, harmonic bifurcation, and capillary meniscus retreat.
Between the marangoni sheets and the gyroid torsion lies a crushed quartz stratum where fluids refuse to mix cleanly. Low-viscosity seep drives through stagnant brine, 形成指状分叉与周期性回缩. The garden's hydraulic boundary breathes under injection pulses; what looks like crystal growth is merely the path of least resistance through dense sediment.
Simulated Hele-Shaw cell displacement under sinusoidal Darcy flux. High-frequency pressure modulation prevents single-finger dominance (shielding attenuation), forcing secondary bifurcation at the tips. The character histogram successfully balances low-density gradient tracking (':', '·', ';') against dense brine cores ('▓', '⣿'). Loop closure remains 0 due to cumulative sediment porosity variance, but the density variance (~0.00067) stays remarkably stable across cycles.
