Tephrochronology and its application: A review [PDF]
Quaternary Geochronology, 2010 Abstract Tephrochronology (from tephra , Gk ‘ashes’) is a unique stratigraphic method for linking, dating, and synchronizing geological, palaeoenvironmental, or archaeological sequences or events. As well as utilizing the Law of Superposition, tephrochronology in practise requires tephra deposits to be characterized (or ‘fingerprinted’) using ...

Tephrochronology in Aotearoa New Zealand [PDF]
New Zealand Journal of Geology, and Geophysics, 2021 ABSTRACT Tephra deposits in Aotearoa New Zealand (ANZ) have been studied for >180 years. The now‐global discipline of tephrochronology, which has some developmental roots in ANZ, forms the basis of a powerful chronostratigraphic correlational tool and age‐equivalent dating method for geological, volcanological, palaeoenvironmental,

High-resolution stalagmite stratigraphy supports the Late Holocene tephrochronology of southernmost Patagonia [PDF]
Communications Earth & Environment, 2022 South Patagonian speleothems yield chemical volcanogenic signals and tephra, which can be used to date regional volcanic eruptions and correlate them with the existing tephrochronology, according to geochemical analyses and micro-/nanoscale observations.

Using Soil Stratigraphy and Tephrochronology to Understand the Origin, Age, and Classification of a Unique Late Quaternary Tephra-Derived Ultisol in Aotearoa New Zealand [PDF]
Quaternary, 2019 In this article, I show how an Ultisol, representative of a globally-important group of soils with clay-rich subsoils, low base saturation, and low fertility, in the central Waikato region in northern North Island, can be evaluated using soil ...

Tephrochronology and Provenance of an Early Pleistocene (Calabrian) Tephra From IODP Expedition 374 Site U1524, Ross Sea (Antarctica) [PDF]
Geochemistry, Geophysics, Geosystems, 2021 We present a full characterization of a 20 cm‐thick tephra layer found intercalated in the marine sediments recovered at Site U1524 during International Ocean Discovery Program (IODP) Expedition 374, in the Ross Sea, Antarctica.

Tephrochronology in faulted Middle Pleistocene tephra layer in the Val dAgri area (Southern Italy)
Annals of Geophysics, 2006 The High Agri River Valley is a Quaternary Basin located along the hinge of the Southern Apennines fold-andthrust belt. The inner margin of the orogen has been affected by intense transtensional and normal faulting, which accompanied vigorous volcanism ...

Tephrochronology and Radiocarbon Chronology in Japan.
The Quaternary Research (Daiyonki-Kenkyu), 2001 テフロクロノロジーと14Cクロノロジーは,火山噴火や縄文遺跡の年代決定によく利用されてきた.より正確な年代決定には両者のクロスチェックが有効であり,試料の形成・保存過程を考慮して年代値が示す意味を検討することが重要である.2つのクロノロジーを用いて検証すると,テフラ直下の埋没土壌の14C年代は,そのテフラの噴出年代を示すことがわかってきた.14C年代はウイグル・マッチング法によって年輪年代学や年縞編年学ともリンクでき,さらに正確な年代を求めることが可能である.泥炭層の14C年代を用いたウイグル・マッチングから,完新世テフラの噴出年代を正確に決定できる可能性がある.

Cosmogenic helium signatures at Deception Island volcano (Antarctica): geochronological implications for its eruptive history [PDF]
Scientific ReportsCosmogenic nuclei production for dating the Earth surface exposure of rock/mineral samples, especially 3He, is a robust technique in geochronology. We describe its application to constrain the ages of key eruptive episodes of the volcanic history of ...

Tephrochronology and Absolute Age Determination
The Quaternary Research (Daiyonki-Kenkyu), 1967 Most tephrochronological studies based upon absolute ages are derived from historical records of eruption and radiocarbon dates from Holocene and Pleistocene times. However, unless associated with some organic matters whose ages are younger than 35, 000 years old, tephra layers usually could not be dated.Recently Kigoshi explored the possibility that ...

Evaluating tephrochronology in the permafrost peatlands of northern Sweden [PDF]
Quaternary Geochronology, 2019 Tephrochronology is an increasingly important tool for the dating of sediment and peat profiles for palaeoecological, palaeoclimatic and archaeological research. However, although much work has been done on tephra in temperate peatlands, there have been very few in-depth investigations of permafrost peatlands.
