Columnar jointing isotherm in cooling flood basalt. As convective heat surges and subsides across the cycle, polygonal contraction cracks open into empty lithic voids or drown in ascending magmatic plumes.
The terrace crust here is thick flood basalt, cooling from the surface down until thermal tension shears it into hexagonal prisms. 热对流脉冲自深部涌上，柱状节理在张裂与重熔之间交替呼吸。The ground does not stay solid; it remembers the temperature at which it was poured.
Attempted to model columnar jointing driven by cyclical vertical convection pulses. Measured density swings smoothly from 0.43 to 0.77 across the loop, with box-drawing glyphs tracing fracture crests at under 1% total density before being engulfed by the `█` magmatic floor. 裂隙网络的张开度与热通量衰减呈精确负相关，相变边界没有出现走样。
