Abstract

A detailed Holocene tephrostratigraphic framework has been developed for two predominately varved
lake sediment sequences from NE Germany (Lake Tiefer See) and central N Poland (Lake Czechowskie). A
total of thirteen tephras and cryptotephras of Icelandic provenance were detected and chemically fingerprinted
in order to define correlatives and to integrate known tephra ages into the sediment chronologies.
Out of these, three cryptotephras (Askja-AD1875, Askja-S and H€asseldalen) were identified in
both records, thus allowing a detailed synchronization of developing high-resolution palaeoenvironmental
proxy data. The early Holocene Saksunarvatn Ash layer and the middle Holocene Lairg-B
and Hekla-4 cryptotephras in Lake Tiefer See are further important anchor points for the comparison
with other high-resolution palaeoclimate records in Central and Northern Europe. Tentative correlations
of cryptotephras have been made with a historical basaltic Grimsv€otn eruption (~AD890 e AD856) and
three late Holocene rhyolitic eruptions, including the 2.1 ka Glen Garry and two unknown high-silicic
cryptotephras of probably Icelandic provenance (~1.9 cal ka BP).
