The application of tephrochronology in Iceland in Tephra studies.
The situation in Iceland for establishing a tephrochronological time scale is very good... Tephrochronology has been applied to studies of the eruption history of the most active volcanoes. It has also been utilised in archaeological research
and palynology, studies of fluvial erosion, wind erosion, and in cryopedological and glaciological research. A tephrochronology correlation between Iceland, the European continent and Greenland has been established.

on the timing of extensive Pleistocene glaciations that affected this area. This approach relies on the tephrochronological method, augmented by glass-fission-track, K-Ar, and TL (thermoluminescence) ages, which are supported at some localities by paleomagnetic
Tephrochronology and palaeoecology: the value of isochrones in Tephra studies.
The applications of tephrochronology to the correlation of temporally similar yet spatially disjunct flora and fauna are discussed, using as examples recent work in Iceland and Kenya. The paucity of such studies is noted and its relevance to studies

Tephrochronology at DSPD site 502 in the western Caribbean in Tephra studies.
A composite core consisting of four Hydraulic Piston Cores at DSDP Site 502 in the western Carribbean were analyzed for dispersed tephra. Peaks in dispersed tephra abundance were combined with megascopic ash layers to produce a tephrochronology
The AA. summarize various estimates of the minimum age of the Summit Lake landslide. Tephrochronology and two-radiocarbon dates establish that the slide was deposited between, 7 840 and 19,000 yr B.P.| age estimates from soil data are less
conclusive, but fall within the range indicated by tephrochronology. Divergence time determined by seriological and morphological characteristics of trout populations (3.8 to 17.2 ka) also is in reasonable agreement with the other estimates.

This study investigates the Holocene chronology of glacier fluctuations in the headwaters of Sredniaya Avacha, a tributary to Avacha. Holocene glacial deposits are subdivided into 3 age groups based upon geomorphic features, tephrochronology
