Role of tephra in dating Polynesian settlement and impact, New Zealand [PDF]

, 2004
Tephrochronology in its original sense is the use of tephra layers as time-stratigraphic marker beds to establish numerical or relative ages (Lowe and Hunt, 2001).

Lateglacial and Holocene glacier variations in an active volcanic area, northern Jan Mayen (Nord‐Jan), Norway

Boreas, Volume 54, Issue 3, Page 305-327, July 2025.
Glacier evolution and environmental changes in the northern Jan‐Mayen from the early deglaciation and well into the Holocene are discussed. Results are based on a large chronological dataset (TCN and radiocarbon dates), integrated with field data on glacial landforms and sediments, including the use of GPR.

Connecting with tephras: principles, functioning, and applications of tephrochronology in Quaternary science [PDF]

, 2013
Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic, or archaeological sequences or events. The method relies firstly on stratigraphy and the law of superposition, which apply in any study that connects

Variations in Event‐Bed Thickness‐Frequency Distributions Near Volcanic Islands: Indicators of Varied Geological Processes

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract A variety of subaerial and submarine events, including mass‐wasting and volcanism, can generate sediment gravity flows and fallout deposits that are preserved in deep‐water stratigraphic records. This study examines whether event beds with differing depositional and transport histories exhibit distinct thickness‐frequency distributions ...

Aligning MIS5 proxy records from Lake Ohrid (FYROM) with independently dated Mediterranean archives: implications for core chronology [PDF]

, 2015
The DEEP site sediment sequence obtained during the ICDP SCOPSCO project at Lake Ohrid was dated using tephrostratigraphic information, cyclostratigraphy, and orbital tuning through marine isotope record.

The Late Quaternary tephrostratigraphy of annually laminated sediments from Meerfelder Maar, Germany [PDF]

Quaternary Science Reviews, 2015
© 2015 Elsevier Ltd.The record of Late Quaternary environmental change within the sediments of Meerfelder Maar in the Eifel region of Germany is renowned for its high precision chronology, which is annually laminated throughout the Last Glacial to Interglacial transition (LGIT) and most of the Holocene.

Paleo‐Earthquake Fingerprints and Along‐Strike Slip Variation of the Silent Mt. Morrone Normal Fault (Central Italy): A Structural‐Geochemical Approach

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 2, February 2025.
Abstract This study provides insights into the tectonic evolution of the normal Mt Morrone Fault System (MMFS) in Central Italy and highlights the utility of multidisciplinary approaches in reconstructing the seismic history of dormant fault systems. The MMFS comprises two parallel normal faults that traverse the western slope of Mt.

Late Holocene palynology and palaeovegetation of tephra-bearing mires at Papamoa and Waihi Beach, western Bay of Plenty, North Island, New Zealand. [PDF]

, 1995
The vegetation history of two mires associated with Holocene dunes near the western Bay of Plenty coast, North Island, New Zealand, is deduced from pollen analysis of two cores.

Increasing Tephra Deposition in Northeastern North America Points to Atmospheric Circulation Changes at the Early Mid Holocene Transition

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 1, 16 January 2025.
Abstract The number of cryptotephra (non‐visible volcanic ash) records from northeastern North America is unique in the continent. The resulting tephrostratigraphic framework includes ash deposits sourced from volcanic arcs across the Northern Hemisphere and is an exceptional resource for correlating and dating paleoenvironmental records.
