causal hypothesis · hyp_bi_exchange_network_reconfiguration
Exchange-network reconfiguration model
Changes in mining, maritime movement, scrap circulation and regional production reflect reconfigured networks rather than the complete disappearance of long-distance exchange.

Research assessment
statement
Changes in mining, maritime movement, scrap circulation and regional production reflect reconfigured networks rather than the complete disappearance of long-distance exchange.proposed mechanism
declining or shifting copper sources; continued tin and copper movement through maritime and down-the-line exchange; greater recycling and episodic cargo loss or depositionmechanisms
- declining or shifting copper sources
- continued tin and copper movement through maritime and down-the-line exchange
- greater recycling and episodic cargo loss or deposition
chronology test
The model predicts continuity of contact alongside changing source signatures and nodes before and after 1200 BCE; Salcombe, Langdon Bay, British tin provenance and Frattesina/Huelva context are compatible.geography test
The model predicts changing concentrations at coastal, riverine and craft nodes, with source-compatible metal and object distributions varying by corridor; it does not predict one fixed route or territorial trading system.important caveat
The volume and frequency of trade remain unknownResearch description
