Bronze Age 'City of Seven Ravines' Revealed as 140-Hectare Planned Settlement With Large-Scale Metallurgy

Peer-reviewed analyses link Semiyarka’s tin to Altai sources, suggesting long-distance supply lines.

Overview

  • An international team from UCL, Durham University and Toraighyrov University reports the findings in Antiquity, confirming a vast ca. 1600 BC settlement in northeastern Kazakhstan.
  • Surveys documented rectilinear earthworks, at least 20 enclosed household compounds likely built in mud brick, and a central monumental building.
  • Crucibles, slag and tin-bronze artefacts identify a dedicated industrial zone for copper and tin-bronze production on an unprecedented scale for the steppe.
  • Geochemical signatures in metallurgical debris match tin deposits in the Altai Mountains roughly 300 kilometers away, indicating distant sourcing.
  • Researchers propose the site functioned along the Irtysh corridor as a production and exchange node, with targeted excavations planned to test settlement chronology and social organization.
