Tephra layers in the marine environment: a review of properties and emplacement processes
A Freundt, JC Schindlbeck-Belo, S Kutterolf… - 2023 - pubs.geoscienceworld.org
This review focuses on the recognition of volcanic ash occurrences in marine sediment
cores and on using their appearance and properties to deduce their origin. Widespread …

Correlating tephras and cryptotephras using glass compositional analyses and numerical and statistical methods: review and evaluation
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 …

Sources of uncertainty in the Mazama isopachs and the implications for interpreting distal tephra deposits from large magnitude eruptions
Estimating the area of tephra fallout and volume of large magnitude eruptions is
fundamental to interpretations of the hazards posed by eruptions of this scale. This study …

Advancing tephrochronology as a global dating tool: applications in volcanology, archaeology, and palaeoclimatic research
Layers of far-travelled volcanic ash (tephra) from explosive volcanic eruptions provide
stratigraphic and numerical dating horizons in sedimentary and volcanic sequences. Such …

The 3.6 ka Aniakchak tephra in the Arctic Ocean: a constraint on the Holocene radiocarbon reservoir age in the Chukchi Sea
The caldera-forming eruption of the Aniakchak volcano in the Aleutian Range on the
Alaskan Peninsula at 3.6 cal kyr BP was one of the largest Holocene eruptions worldwide …

Large-scale pore network and continuum simulations of solute longitudinal dispersivity of a saturated sand column
Predicting the solute dispersivity in porous media is complicated by the known scale
dependency of dispersion processes. In this study, we combined three complementary …

High-resolution age modelling of peat bogs from northern Alberta, Canada, using pre-and post-bomb 14C, 210Pb and historical cryptotephra
High-resolution studies of peat profiles are frequently undertaken to investigate natural and
anthropogenic disturbances over time. However, overlap** profiles of the most commonly …
