Tephrochronology of the Miocene Santa Cruz and Pinturas Formations, Argentina

, 2012
The Santa Cruz and Pinturas Formations (SCF and PF) are two partially coeval formations in the southern part of Santa Cruz Province, Argentina, that were deposited during the Early to Middle Miocene.

Connecting, synchronising, and dating with tephras: principles and applications of tephrochronology in Quaternary research

, 2016
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

A database of paleoceanographic sediment cores from the North Pacific, 1951–2016 [PDF]

Earth System Science Data, 2017
We assessed sediment coring, data acquisition, and publications from the North Pacific (north of 30° N) from 1951 to 2016. There are 2134 sediment cores collected by American, French, Japanese, Russian, and international research vessels across the ...

Tephra without borders: Far-reaching clues into past explosive eruptions

Frontiers in Earth Science, 2015
This review is intended to highlight recent exciting advances in the study of distal (>100 km from the source) tephra and cryptotephra deposits and their potential application for volcanology.

Distal occurrence of mid-Holocene Whakatane Tephra on the Chatham Islands, New Zealand, and potential for cryptotephra studies

, 2011
The Whakatane Tephra, a rhyolitic tephra erupted ca. 5500 cal. BP from Okataina Volcanic Centre, central North Island, has been identified on the Chatham Islands which lie ˜900 km east of Christchurch, New Zealand.

Cryptotephra in the East Antarctic Mount Brown South ice core [PDF]

Climate of the Past
Ice cores contain stratified layers of impurities scavenged from the atmosphere, which are a vital tool for investigating the Earth system. Reconstructing past eruption records by way of ice core tephrochronology can help us understand ash dispersal ...

Vegetational response to tephra deposition and land-use change in Iceland: a modern analogue and multiple working hypothesis approach to tephropalynology [PDF]

, 2004
Evidence is provided from the joint application of tephrochronology and palynology in two Icelandic locations — the island of Papey off the east coast and Seljaland in the south.
