"This is during or shortly after the bronze age collapse..." Shortly before (13-12th century BCE) the "collapse" (12-11th century BCE). From the PLOS One conclusions: "Although many questions remain unanswered and new ones arose, the integrated approach of using trace elements, tin and lead isotopes turns out to be a promising tool for provenancing and fingerprinting ancient tin objects. It should be followed up by future archaeometallurgical research in order to unravel the enigma of BA tin. In this form, our study should stimulate new discussions on the provenance of tin of the Eurasian BA rather than postulating an origin from a specific deposit." https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0218326 https://journals.plos.org/plosone/article?id=10.1371/journal...
