Petrogenesis of the Sólheimar ignimbrite (Katla, Iceland): Implications for tephrostratigraphy

Geochimica et Cosmochimica Acta, 2012
The Sólheimar ignimbrite was one of the largest eruptions from the Katla caldera (Iceland) and is important for tephra studies in the North Atlantic because of its possible linkage with the Vedde Ash, a compositionally bimodal tephra layer used for correlation of sedimentary records in the North Atlantic and Northern Europe.

Tephrochronology and tephrostratigraphy of western Taranaki (N108–109), New Zealand

New Zealand Journal of Geology and Geophysics, 1972
Abstract Ten newly named formations and members of ash and lapilli, erupted from Mt Egmont and the Pouakai Range, comprise the principal tephras mantling the western Taranaki landscape. They are overlain by nine restricted younger eruptives, previously described by Druce, which are also summarised in this paper.

Tephrostratigraphy of the late Quaternary record from Lake Chalco, central México

Journal of South American Earth Sciences, 2018
Abstract Lacustrine sequences in active volcanic settings preserve the record of fall-out products (tephras) from explosive volcanic activity from both proximal and distal sources. Sediments of Lake Chalco, located in the western part of the Trans Mexican Volcanic Belt, offer the opportunity to develop a detailed tephrostratigraphy of proximal and ...

The potential of Late Quaternary tephrostratigraphy and cryptotephrostraygraphy of the Eastern Adriatic coast

2015
Tephra layers are significant in palaeoenvironmental research on the Eastern Adriatic coast and they can be linked to specific eruption events in proximal volcanic settings. These distal tephra records are sometimes extremely thin and barely visible or are not visible at all (“cryptotephra” layers), but they can be traced over greater distances from ...

Tephrostratigraphy and paleoenvironments of the late Quaternary in eastern Beringia

2013
In this dissertation, tephrostratigraphy is used as the central method to address issues of chronology in the late Quaternary sedimentary record of eastern Beringia (non-glaciated Yukon and Alaska) at a variety of spatial and temporal scales. The Palisades, central Alaska, preserves paleoenvironmental records thought to span, with major unconformities,

Tephrostratigraphy and hominin paleoenvironments of the Hadar Formation, Afar Depression, Ethiopia

2007
The deposits of the Hadar Formation preserve a continuous record of hominin habitats and environmental change from ca. 3.45 Ma until a regional disconformity at ca. 2.9 Ma. At Hadar, strata below the disconformity are composed of fluvial sands and well-developed claystone paleosols associated with a large-scale meandering river system and several brief
