Tephrochronology of the Toluca Basin, central Mexico

Quaternary Science Reviews, 1999
Abstract The major element glass geochemistry of 10 Late Pleistocene and Holocene tephras found in the Toluca Basin in the Trans-Mexican Volcanic Belt is reported for the first time, as a key step towards establishing a tephrochronology for the region.

Central Mediterranean explosive volcanism and tephrochronology during the last 630 ka based on the sediment record from Lake Ohrid

, 2019
Lake Ohrid, located in the Central Mediterranean region downwind of the Italian volcanoes, has great potential for developing a detailed record of the explosive activity of these volcanoes.

Pollen analysis and tephrochronology of a MIS 13 lacustrine succession from Eastern Sabatini Volcanic District (Rignano Flaminio, central Italy)

Quaternary Science Reviews, 2019
Diatomite deposits in the Sabatini Volcanic District (central Italy) represent valuable archives to investigate both Middle Pleistocene vegetation dynamics and geochemistry of proximal products of volcanic eruptions, which provide crucial ...

Rhyolitic and dacitic component of the Askja 1875 tephra in southern and central Finland: first step towards a Finnish tephrochronology

Journal of Quaternary Science, 2018
Tephra from Icelandic volcanic eruptions is frequently dispersed to northern Europe, but so far tephra has not been detected in Finnish sedimentary records. We report the first finding of a cryptotephra layer in southern and central Finland.

Tephrochronology: a New Zealand case study

Earth-Science Reviews, 2000
Abstract Tephrochronology is the study of volcanic ash (tephra) beds for the purpose of correlating and dating volcanic and other geologic events. Large magnitude silicic eruptions can disperse tephra up to thousands of kilometres from the vent, producing a near instantaneous marker horizon.

Tephrochronology by Microprobe Glass Analysis

1981
Basaltic tephra layers form a considerable part of the postglacial tephra deposits in Iceland. They can be related to the volcanic systems that produced them by characteristics based on major and minor element chemistry. Microprobe analysis of volcanic glass shards have made it possible to relate even very thin (1–2 mm) basaltic tephra layers in distal
