Lichenometry dating of coseismic changes to a New Zealand landslide complex [PDF]

open access: yesAnnals of Geophysics, 2003
Lichenometry is a surface-exposure-dating procedure that complements traditional trench-and-date stratigraphic studies of earthquakes. Lichens on the surficial blocks of a slump in the Seaward Kaikoura Range, South Island, New Zealand provide ...

Absolute and relative age of moraines of the Aktru and Historical stages of glaciers of Central Altai based on lichenometry and dendrochronology [PDF]

open access: yesЛëд и снег, 2022
Dendrochronology, and lichenometry were used to determine the relative and absolute age of the Late Holocene moraines of the glaciers of the Aktru, Maashei and Shavla valleys (North Chuya ridge, Central Altai).

Lichenometric Dating and Its Limitations and Problems: A Guide for Practitioners

open access: yesLand, 2023
Lichenometry, a method for dating rock surface exposure mainly in high latitudes and mountain environments, is based on estimates of lichen growth rates, but over the last 70 years it has been severely criticised. Its chief limitation is its questionable

First 10Be dates of late holocene moraines of the Kashkatash and Irik glaciers, Northern Caucasus

open access: yesЛëд и снег, 2023
We present 11 10Be ages of the moraines of the Irik and Kashkatash glaciers that allowed identifying and dating several Late Holocene glacier advances for the first time, including a prominent advance exceeding the Little Ice Age (LIA) maximum that ...

Lichenometric Analysis Applied to Bedrock Fault Scarps: The Sencelles Fault and the 1851 CE Mallorca Earthquake (Balearic Islands, Spain)

open access: yesApplied Sciences, 2023
The Sencelles Fault constitutes the main extensional structure of Mallorca Island (Spain), holds a NE-SE orientation, and has been identified as the possible seismic source of the 1851 CE Palma earthquake (VII EMS.) The SE termination of the fault (Sta ...

Timing of Little Ice Age maxima and subsequent glacier retreat in northern Troms and western Finnmark, northern Norway

open access: yesArctic, Antarctic, and Alpine Research, 2020
Glaciers are important indicators of climate change, and recent observations worldwide document increasing rates of mountain glacier recession. Here we present approximately 200 years of change in mountain glacier extent in northern Troms and western ...

Plant succession on glacial moraines in the Arctic Brooks Range along a >125,000-year glacial chronosequence/toposequence

open access: yesArctic, Antarctic, and Alpine Research, 2023
Widespread glacial retreat is now occurring in many arctic mountain ranges, yet little is known about primary succession following deglaciation in these settings.

Changement climatique et atrophie des masses glaciaires : quelles mutations pour les paysages islandais ?

open access: yesEchoGéo, 2008
The Global Warming which occurs since the end of the Little Ice Age in Iceland leads to the retreat of the glacier fronts. This retreat has induced new dynamics in the glacier foreland, especially related to glacial meltwater and post-glacial release ...

Glaciers of Avacha group of volcanoes in Neoholocene

open access: yesЛëд и снег, 2016
The study of moraines at the Avacha volcano group revealed that glaciers changes at all volcanoes within the group happened almost synchronously.

KASHKATASH GLACIER FLUCTUATIONS IN THE XVII–XXI CENTURIES FROM CARTOGRAPHIC, DENDROCHRONOLOGICAL AND LICHENOMETRIC DATA

open access: yesЛëд и снег, 2015
We focused our study on the retreat of a typical valley glacier Kashkatash, located in the Elbrus Area. We compared the old photographs of the glacier forefields (H. Burmester, 1911; H. Altberg, 1927; E.N.
