Iron‐Bearing Minerals as Potential Indicators of Paleo‐Methane Seepage Evolution

Journal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract Methane (CH4) release and consumption in marine cold seeps are key processes influencing seabed ecology, global climate reconstruction, and hydrate resource exploration. Anaerobic oxidation of methane (AOM), the primary methane consumption mechanism, typically couples with microbial sulfate or metal reduction.

The international tephra research group ‘Commission on Tephrochronology’ and its activities – the first 60 years

, 2021
. Modern tephra studies per se began almost 100 years ago (in the late 1920s) but the first collective of tephrochronologists, with a common purpose and nascent global outlook, was not formed until 7 September, 1961, in Warsaw, Poland.

Tephrochronology and the late Holocene volcanic and flood history of Eyjafjallajökull, Iceland [PDF]

, 2013
The hugely disruptive Eyjafjallajökull eruptions of 2010 AD are well known, but the recent history of the volcano is not, which compromises both Icelandic and international hazard assessments and risk planning.

Climate variability over the last 92 ka in SW Balkans from analysis of sediments from Lake Prespa [PDF]

Climate of the Past, 2014
The transboundary Lake Prespa (Albania/former Yugoslav Republic of Macedonia/Greece) has been recognized as a conservation priority wetland. The high biodiversity encountered in the catchment at present points to the refugial character of this ...

Stratigraphy and chronology of the Stent tephra, a c. 4000 year old distal silicic tephra from Taupo Volcanic Centre, New Zealand. [PDF]

, 1994
Tephrostratigraphic and chronologic studies in two areas of the North Island have identified a previously unrecorded, thin, distal silicic tephra derived from the Taupo Volcanic Centre.

Tephrochronology in faulted Middle Pleistocene tephra layer in the Val d’Agri 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 ...

Unravelling upbuilding pedogenesis in tephra and loess sequences in New Zealand using tephrochronology [PDF]

, 2010
The genesis of soils developed in either tephra or loess on stable sites differs markedly from that of soils developed on rock because classical topdown processes operate in conjuction with geological processes whereby material is added to the land ...

Late-Holocene land surface change in a coupled social-ecological system, southern Iceland : a cross-scale tephrochronology approach [PDF]

, 2014
This work is supported by a UK Natural Environment Research Council (NERC) PhD studentship (NE/F00799X/1)The chronological challenge of cross-scale analysis within coupled socio-ecological systems can be met with tephrochronology based on numerous well ...

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.

Building an 18 000-year-long paleo-earthquake record from detailed deep-sea turbidite characterisation in Poverty Bay, New Zealand [PDF]

Natural Hazards and Earth System Sciences, 2012
Two ~20 m-long sedimentary cores collected in two neighbouring mid-slope basins of the Paritu Turbidite System in Poverty Bay, east of New Zealand, show a high concentration of turbidites (5 to 6 turbidites per meter), interlaid with hemipelagites ...
