Abstract:
We investigated marine sediment core GS16-204-22CC for increased tephra occurrences and geochemically analysed the major element composition of tephra shards to identify their source volcano(es). In total we observed eight tephra zones of which five concentration peaks show isochronous features that can be used as independent tie-points in future studies. To ensure analytical precision, secondary standards (BCR2g (Basalt) and Lipari Obsidian (Rhyolitic)) were measured at the start and end of each run.
