The ‘Roxolany Tephra’ (Ukraine) – new evidence for an origin from Ciomadul volcano, East Carpathians [PDF]
We present major element glass data and correlations for the ‘Roxolany Tephra’ - a so far geochemically unconstrained volcanic ash layer previously described in last glacial (Marine Isotope Stage 2) loess deposits of the Roxolany loess–palaeosol complex ...

Krasheninnikov Caldera (Eastern Kamchatka): age and magnitude of eruption
New data on the composition of the pyroclastic deposits of the Krasheninnikov caldera allowed us to correlate it to the previously studied tephra horizon Geys30, which until recently was erroneously attributed to an eruption within the Geysernaya caldera.

Discovery of halloysite books in a ~270,000 year-old buried tephra deposit in northern New Zealand
As part of a wider study examining the geomechanical properties, especially sensitivity, of sequences of Quaternary pyroclastic and associated deposits and buried soils in the landslide-prone western Bay of Plenty area near Tauranga, eastern North Island,

Tephra fall clean-up in urban environments [PDF]
Tephra falls impact urban communities by disrupting transport systems, contaminating and damaging buildings and infrastructures, and are potentially hazardous to human health.

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 ...

Peatlands, volcanoes and climate: Ecological and palaeoecological studies in Alaska and Scotland
PhDThis thesis investigates direct and indirect volcanic impacts on peatlands using palaeoecological and ecological techniques. The primary approach used is palaeoecological studies across tephra layers. A multi-proxy methodology was adopted including

Tephras are important for the NZ-INTIMATE project because they link all three records comprising the composite inter-regional stratotype developed for the New Zealand climate event stratigraphy (NZ-CES).

Age of the Rotoehu Ash. Comment.
Suggests that the article by Whitehead & Ditchburn (1994), although presenting useful new data on 230Th/232Th analyses, is flawed and misleading in suggesting that the Rotoiti Tephra is considerably younger than c.

Tephra-stack of combined sediment record ELSA
Tephra layers of individual volcanic eruptions are traced in several cores from Eifel maar lakes, drilled between 1998 and 2014 by the Eifel Laminated Sediment Archive (ELSA).

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
