High-resolution tephrochronology resolves stratigraphic complexities in archaeologically significant Nariokotome tuffs, Turkana Basin. [PDF]

open access: yesProc Natl Acad Sci U S A
Significance The Nariokotome Tuff Complex in the Turkana Basin, Kenya, hosts rare late Early Pleistocene paleoanthropological sites crucial for understanding Homo erectus and their associated cultural technology, highlighted by decades of remarkable ...

TEPHROCHRONOLOGY [PDF]

open access: yes, 2014
Tephrochronology is the use of primary, characterized tephras or cryptotephras as chronostratigraphic marker beds to connect and synchronize geological, paleoenvironmental, or archaeological sequences or events, or soils/paleosols, and, uniquely, to transfer relative or numerical ages or dates to them using stratigraphic and age information together ...

Ordovician tephra distribution, tephrochronology and geochronology

open access: yesGeological Society, London, Special Publications, 2023
Abstract The study of Ordovician tephras yields a wealth of valuable information about regional tectonism, sedimentation, stratigraphic correlation, and process rates. As such, these layers are prized by geologists and are the subject of a rich literature.

Tephrochronology in Aotearoa New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, 2021
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, and archaeological ...

Global tephra studies: role and importance of the international tephra research group “Commission on Tephrochronology” in its first 60 years [PDF]

open access: yesHistory of Geo- and Space Sciences, 2022
. Tephrochronology is a correlational and age-equivalent dating method whereby practitioners characterize, map, and date tephra (or volcanic ash) layers and use them stratigraphically as connecting and dating tools in the geosciences (including ...

Synchronous or Not? The Timing of the Younger Dryas and Greenland Stadial-1 Reviewed Using Tephrochronology

open access: yesQuaternary, 2022
The exact spatial and temporal behaviour of rapid climate shifts during the Last Glacial–Interglacial Transition are still not entirely understood. In order to investigate these events, it is necessary to have detailed palaeoenvironmental reconstructions

Central Mediterranean tephrochronology for the time interval 250–315 ka derived from the Fucino sediment succession

open access: yesBoreas, 2023
In the lacustrine succession F4‐F5 of the Fucino Basin, central Italy, 20 visible tephra layers were identified in the time interval 250–315 ka (Marine Isotope Stages 8–9).

Central Mediterranean tephrochronology between 313 and 366 ka: New insights from the Fucino palaeolake sediment succession

open access: yesBoreas, 2022
Thirty‐two tephra layers were identified in the time‐interval 313–366 ka (Marine Isotope Stages 9–10) of the Quaternary lacustrine succession of the Fucino Basin, central Italy. Twenty‐seven of these tephra layers yielded suitable geochemical material to

Radiocarbon Dating and Tephrochronology in Kamchatka [PDF]

open access: yesRadiocarbon, 1993
We discuss results of 14C dates obtained from areas of young volcanoes in Kamchatka. We apply these dates to reconstructing regional volcanic activity during the Holocene.

Post–glacial tephrochronology record off the Chilean continental margin (∼41° S)

open access: yesQuaternary Science Reviews, 2021
The Southern Volcanic Zone of the Andes (∼33–46° S) is a very active volcanic zone with several volcanic centers recording recurrent historical activity (e.g. Llaima, Villarrica, Puyehue-Cordon Caulle, Osorno, Calbuco and Hudson).
