Geochemical fingerprinting of Icelandic silicic Holocene tephra layers [PDF]

, 2012
The overall aim of this research project has been to develop a reference dataset of 19 Holocene silicic Icelandic tephra layers sourced from the Torfajökull, Askja, Katla, Öræfajökull and Hekla volcanic systems.

Temporal evolution of roof collapse from tephra fallout during the 2021-Tajogaite eruption (La Palma, Spain)

Frontiers in Earth Science
Although dominantly effusive, the 2021 Tajogaite eruption from Cumbre Vieja volcano (La Palma, Spain) produced a wide tephra blanket over 85 days of activity.

Sensitivity and clay mineralogy of weathered tephra-derived soil materials in the Tauranga region

, 2009
Soil sensitivity is defined as the ratio of peak to remoulded shear strength. Problem soil materials are those that show large strength losses on disruption, resulting in catastrophic failure, liquefaction and long run-out distances.

Clay mineralogy of tephras and associated paleosols and soils, and hydrothermal deposits, North Island [New Zealand]

, 1993
Tour themes and itinerary The tour centres on the occurrence and genesis of clay minerals, especially allophane, halloysite, and ferrihydrite, associated with both Quaternary rhyolitic airfall tephra (volcanic ash) deposits and volcanogenic alluvium ...

Improvement in soil water availability in pastures by excavating and mixing buried soil horizons from multilayered Pumice Soils (Vitrands) at Galatea, central North Island, New Zealand

, 2014
Pumice Soils (Typic Udivitrands) in the Galatea Basin in the eastern Bay of Plenty, central North Island, New Zealand, are formed on weakly weathered, coarse textured, glassy, pumice tephra deposits and associated buried soil horizons.

New Early Holocene tephra horizons from the Faroe Islands

, 2010
The early Holocene climate in the North Atlantic region was rather unstable and three cold events superimposed upon a general warming took place during the earliest part of the Holocene: the Preboreal oscillation (11.3-11.1 ka BP), the Erdalen event (10 ...
