| Zusammenfassung |
| Volcanic tephra are independent age horizons and can synchronize strata of
various paleoclimate records including ice and sediment cores. The Holocene
section of the Greenland Ice Core Project (GRIP) ice core is dated by
multi-parameter annual layer counting, and contains peaks in acidity,
SO42− and microparticle concentrations at a depth of 429.1 to
429.3 m, which have not previously been definitively ascribed to a volcanic
eruption. Here, we identify tephra particles and determine that volcanic
shards extracted from a depth of 429.3 m in the GRIP ice core are likely due
to the 79 AD Vesuvius eruption. The chemical composition of the tephra
particles is consistent with the K-phonolitic composition of the Vesuvius
juvenile ejecta and differs from the chemical composition of other major
eruptions (≥ VEI 4) between 50–100 AD. |
