Electron probe microanalysis of extremely fine‐grained tephras: new protocols and insights for analyses at the 1 μ ${\rm{\mu }}$m scale

open access: yesJournal of Quaternary Science, EarlyView.
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
