Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool
ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

ABSTRACT Volcanic ash (tephra) provides an important chronostratigraphic framework for correlating Quaternary records. In ultra‐distal ( > $\gt $1500 km) settings such as ice cores and marine sediments, deposits are typically preserved as cryptotephra composed of glass shards ≤ 20 μ $\le 20\,\mu

ABSTRACT In this study, we report the first documented occurrence of the Icelandic Vedde Ash (VA) in the Bohemian Forest, identified within palaeolake sediments from Stará Jímka, Czechia, representing the first Icelandic tephra layer identified in Czechia.

ABSTRACT Glacial/interglacial climate cycles since marine isotope stage (MIS) 12 influenced the discontinuous and 73 m‐long sediment record from the volcanic crater of Rodderberg in the East Eifel Volcanic Field, Germany. High‐resolution grain size and geochemical data have been valued by numerical dating techniques (radiocarbon and luminescence dating,
