Integrated tephrostratigraphy and stable isotope stratigraphy in the Japan Sea and East China Sea using IODP Sites U1426, U1427, and U1429, Expedition 346 Asian Monsoon

Progress in Earth and Planetary Science, 2018
Integrated Ocean Drilling Program Expedition 346 “Asian Monsoon” obtained sediment successions at seven sites in the Japan Sea (Sites U1422–U1427 and U1430) and at two closely located sites in the northern East China Sea (Sites U1428 and U1429).

High-precision tephrostratigraphy : tracking the time-varying eruption pulse of Mt. Taranaki, North Island, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Earth Science, Massey University, Palmerston North, New Zealand [PDF]

, 2017
In this research it was proposed that a more robust record of volcanic activity for Mt. Taranaki (New Zealand) could be derived from tephras (pyroclastic fall deposits) within cores from several lakes and peatlands across a 120o arc, NE-SE of the ...

Tephrostratigraphy of paleoclimatic archives in central Mediterranean during the Bronze Age [PDF]

Quaternary International, 2019
Abstract Re-examination of central Mediterranean paleoclimate archives on tephra layers indicates that three widely dispersed tephra layers occurred during the Bronze Age, namely Agnano Mt Spina from Campi Flegrei (ca. 4.4 cal ka BP), Avellino from Somma-Vesuvius (ca. 3.9 cal ka BP), and FL from Etna (ca. 3.3 cal ka BP).

Challenges in dating blanket peat and implications for understanding its initiation in Ireland

Journal of Quaternary Science, Volume 40, Issue 6, Page 996-1009, August 2025.
ABSTRACT Blanket peat is widespread in maritime extra‐tropical environments. Prehistoric land‐use activity was traditionally invoked as the stimulus of blanket peat initiation in the British Isles, but recently, climate has been viewed as the driver of peat formation.

Tephrostratigraphy arid chronology of the kaipo lagoon, an 11, 500 year-old montane peat bog in urewera national Park, New Zealand [PDF]

, 1986
Eleven well-preserved Holocene tephras occur interbedded with peat in the Kaipo Lagoon bog in Urewera National Park, North Island. They are identified chiefly by their field appearance, stratigraphy, and ferromagnesian mineralogy.

Cryptotephra from a ~120 ka Tondano eruption in a sediment core from Lake Towuti (Indonesia)

Journal of Quaternary Science, Volume 40, Issue 5, Page 741-746, July 2025.
ABSTRACT Southeast Asia is one of the most volcanically active regions in the world, yet their long‐term eruptive history has been comparatively little studied. In particular, little work has explored the potential of sedimentary archives to record distal cryptotephra, which may help in identifying some of the region's larger Quaternary eruptions. Here,

Tephrochronology: principles, functioning, application [PDF]

, 2011
Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic or archaeological sequences or events. The method relies firstly and fundamentally on stratigraphy and the law of superposition, which apply in any ...

Re-identification of c. 15 700 cal yr BP tephra bed at Kaipo Bog, eastern North Island: implications for dispersal of Rotorua and Puketarata tephra beds. [PDF]

, 2003
A 10 mm thick, c. 15 700 calendar yr BP (c. 13 100 14C yr BP) rhyolitic tephra bed in the well-studied montane Kaipo Bog sequence of eastern North Island was previously correlated with Maroa-derived Puketarata Tephra.

A long postglacial rhyolitic activity of the Icelandic Krafla volcano during the Eemian: limited impact of glacio-isostasy

BSGF - Earth Sciences Bulletin
Tephrostratigraphy in marine cores is an important tool for dating sedimentary sequences along the North Atlantic and in Western Europe. Most previously analyzed marine tephra were produced by Icelandic volcanoes, albeit rarely from the Krafla volcano ...

Volcanically induced glacier collapses in southern Jan Mayen (Sør‐Jan), Norway

Boreas, Volume 54, Issue 3, Page 395-413, July 2025.
A formerly unknown glacier totally covered with tephra was found in an area of Jan Mayen where no Holocene glaciation was known. This glacier and three others in the same area melted abruptly creating jökulhlaups due to volcanic activity impacting the glacier catchments at different times in the Holocene.
