Geological systems frequently evolve through gradual change. However, some transitions appear to occur at identifiable thresholds where structural behavior, deformation style, sedimentary architecture, or topographic expression changes significantly.
This paper evaluates geological thresholds through deformation intensity, fault-system organization, basin geometry, relief gradients, lithologic transitions, and regional continuity.
Reference systems include the Zagros Fold Belt, Himalayan deformation front, East African Rift, Dead Sea Transform, Andean margin, and selected sedimentary basin provinces.
The objective is to determine whether recurring threshold behavior can be identified across diverse geological environments.
Within ABC Sequencing, thresholds are treated as observational markers where gradual variation may transition into a different structural regime.
The framework emphasizes measurable changes in geological expression rather than inferred process alone.
This paper evaluates geological thresholds as recurring points where structural, tectonic, or depositional behavior changes in measurable ways.
