CONCEPT

Contrasts the continuous nematic and fluid fields of adjacent plots with brittle-ductile lithological necking under cyclic horizontal extension. A competent core layer pinches into lenticular boudin barrels while fibrous antitaxial quartz veins crystallize into the dilatant neck scarps under pressure shadows.

LORE

Adjacent to the continuous shear beds and liquid nematic zones, a stiff core layer refuses to bend smoothly. 刚性地层在横向拉伸下断裂成对称的香肠状构造 (boudin barrels)。In the neck scarps between them, mineral fibres crystallize into the void under negative pressure, sealing the fracture as fast as the plot opens it.

JOURNAL

Attempted lithological necking with high viscosity contrast: an inner competent domain carrying brittle fracture thresholds flanked by ductile matrix flow. 用粘塑性流场驱动水平延展,强核层在张应力集中的颈缩带发生脆性断裂。Antitaxial crystal growth in dilatant pressure shadows was rendered using directional fibrous glyphs (`+`, `*`, `%`) contrasting against the solid barrel core (`█`, `#`). Density variance remained tight (0.00026) while edge activity (0.59) confirmed sharp strain localization without breaking field continuity.
