We define tephras and cryptotephras and their components (mainly ash-sized particles of
glass±crystals in distal deposits) and summarize the basis of tephrochronology as a …

Evidence for a major climate event at 5.2 ka has been reported globally and is associated
with considerable societal disruption, but is poorly characterised in northwest Europe. This …

Lakes and bogs in northeastern North America preserve tephra deposits sourced from
multiple volcanic systems in the Northern Hemisphere. However, most studies of these …

Contemporary measurements of carbon (C) accumulation rates in peatlands around the
world often show the C sink to be stronger on average than at times in the past. Alteration of …

Holocene cryptotephras of Alaskan and Pacific Northwestern origin have recently been
detected ca. 7000 km away on the east coast of North America. This study extends the …

High-resolution studies of peat profiles are frequently undertaken to investigate natural and
anthropogenic disturbances over time. However, overlap** profiles of the most commonly …

There have been few detailed studies into the tephrostratigraphy of southern Britain. We
report the tephrostratigraphy of two sites, one in southern England (Rough Tor, Cornwall) …

Cryptotephras in peat and sediment samples are traditionally separated for geochemical
characterization using chemical or density floatation techniques following initial tephra …

Abstract Microscopic tephra layers ('cryptotephras') represent important age-equivalent
stratigraphic markers utilised in many palaeoenvironmental reconstructions. When used in …

Despite the discovery of cryptotephra layers in over 100 peatlands across northern Europe,
Holocene cryptotephra layers have not previously been reported from Polish peatlands …
