Research assessment
statement
Local geomorphic disturbance, rather than regional societal collapse, caused at least one depositional break at Chap.mechanisms
- Dust deposition, slope failure or other local landscape processes can cover occupation surfaces and interrupt site use without depopulating the wider valley.
chronology test
Sediment signatures should distinguish aeolian from mass-movement deposition.geography test
Contemporary occupation should persist at other valley locations if disruption was local.supporting evidence
- Geoarchaeological comparison of dust-storm and landslide mechanisms
important caveat
Chronological and geographic overlap are necessary but not sufficient for causation.Research description
