Abstract

We present the findings of a detailed non-visible (cryptotephra) tephra investigation of the Lake Suigetsu (Japan) sedimentary sequence spanning ~120 to 50 ka. Thirty-nine new cryptotephra and two visible tephra horizons are identified during this interval interspersed between visible tephra layers...

Thirty-nine new cryptotephra and two visible tephra horizons are identified during this interval interspersed between visible tephra layers associated with large-magnitude eruptions and regional event markers (e.g., Aso-4, K-Tz, Ata). The newly identified volcanic deposits are geochemically analysed using major (EMP) and trace (LA-ICP-MS) element glass analyses, and the chemical fingerprints are used to trace these deposits to subduction related volcanoes located along the three main Japanese islands (Kyushu, Honshu and Hokkaido), as well as nearby intraplate volcanoes.
