Review and provenance

Specialist reviewer: not recorded. Review date: not recorded.

Dataset workflow: proposed. This is separate from specialist review.

Confidence describes the stated assessment; it does not certify expert approval. How review works.

Chronology

Dating intervals may describe uncertainty or phases; their width alone does not establish event duration.

Preferred assertion

1900 BCE–1500 BCE

Precision: range

moderate

Contextual record outside all or part of the primary interval.

Interpretation and caveats

The evidence supports regional contraction, relocation, technological continuity and new community configurations rather than a single collapse or replacement event.

Event context

Classification

Event type: oasis system reorganization

Evidence layer: archaeological

Timeline role: regional core

Why it matters to the timeline

The transition directly structures the southern Central Asian interval and its links to Afghanistan and Iran.

Research notes

  • Defines the mature complex and transition problem. Role: contextualizes. Locator: Chronology and regional diversity.
  • Documents continuity and interaction outside urban centers. Role: provides archaeological observation. Locator: Mobile occupation during the transition.
  • Provides landscape-scale change. Role: contextualizes. Locator: Settlement and hydrological reorganization.
