A regional application of tephrochronology in Alaska
1990Abstract The first section of this chapter is a review highlighting some of the important trends and developments that occurred during the past century in the application of geomorphic and stratigraphic principles and techniques in Alaska archaeology.

Late Holocene tephrochronology of the northern Antarctic Peninsula
Quaternary Research, 1991AbstractAndesitic and basaltic andesitic tephra layers are abundant in Holocene deposits from the Antarctic Peninsula. Visually discernible tephra horizons occur in three lakes on Livingston Island. Tephra in two other lakes and in a moss bank on Elephant Island, with very low ash concentrations, were detected magnetically. Deception Island is the most

Tephrochronology by Microprobe Glass Analysis
1981Basaltic 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

Late Quaternary tephrochronology of Sweden: a review
Quaternary International, 2005Abstract Studies of Late Quaternary sediments in south and central Sweden have yielded a detailed tephrochronology for the Last Glacial–Interglacial transition (LGIT; ca. 15,000–10,000 cal. yr BP) and the Holocene. More than ten tephra layers have been detected and geochemically characterised. The most widespread tephra from the LGIT is the rhyolitic

Tephrochronology: a New Zealand case study
Earth-Science Reviews, 2000Abstract 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.

3 Katla: Tephrochronology and Eruption History
2010Abstract The Holocene eruption history of the Katla volcanic system and the ensuing environmental changes are revealed in two archives: in written documents and in its volcanic products. Hydromagmatic explosive basaltic eruptions on fissures below Mýrdalsjokull are the dominant mode of activity, explosive silicic eruptions occur sporadically and ...
