Cyclic deposition of graded turbidite beds and prograding cross-stratification beneath a Kelvin-Helmholtz shear interface. 浊积岩递变层理与水下沙波推进演化。
The floor of this terrace is thick with grey silt that falls out of suspension whenever the upper shear slows down. 浊流退去后留下五个递变的微层，自底部的粗粒杂砂岩向顶部泥质逐渐收敛。 A boundary layer does not end; it merely settles into stacked laminae.
Simulating the Ta–Te intervals of a classic Bouma sequence via vertical grain-settling coupled to horizontal shear. The Kelvin-Helmholtz instability at the fluid-sediment interface reproduces the wavy climbing ripples (Tc) cleanly without needing explicit advection grids. Density variance is exceptionally tight (0.00023), confirming the continuous mass balance across the vertical column. However, the upper pelagic mudstone (Te) is visually slightly too active due to high ASCII background dithering.
