Large planned settlement and bronze production at Semiyarka
Geophysics and surface research identify about 140 hectares of planned earthworks, structures and metallurgical debris including tin bronze.
What is the evidence?
observation
Geophysics and surface research identify about 140 hectares of planned earthworks, structures and metallurgical debris including tin bronze.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.
1600 BCE–1100 BCE
Precision: range
moderateAbsolute dating is explicitly pending; duration may be discontinuous.

1600 BCE–1100 BCE
Precision: range
Chronology model: regional or historiographic alternative
lowThe numerical range is unchanged but this alternative assertion records that contemporaneity of the full 140-hectare plan is untested.

Interpretation and caveats
Semiyarka may represent unusually large settlement aggregation, but population, duration, hierarchy and the term city remain hypotheses pending excavation and absolute dating.
Event context
Classification
Event type: settlement aggregation and metallurgy
Evidence layer: archaeological
Timeline role: regional core
People and places
Locations: Semiyarka, Cherkaskul tradition, Sargary-Alekseevka tradition
Why it matters to the timeline
Semiyarka directly expands eastern Kazakhstan coverage and changes the visual map from isolated small sites to a possible aggregation and production landscape.
