Tephrochronology by Microprobe Glass Analysis
Basaltic tephra layers form a considerable part of the postglacial tephra deposits in Iceland. They can be related to the volcanic systems that produced them by characteristics based on major and minor element chemistry. Microprobe analysis of volcanic glass shards have made it possible to relate even very thin (1–2 mm) basaltic tephra layers in distal areas outside the volcanic zones to their source.
