A lichenometric study of the Neoglacial end moraines of the Okstindan Glaciers, North Norway, and comparisons with similar recent Scandinavian studies

A lichenometric test of the 1750 end-moraine hypothesis: Storbreen gletscervorfeld, Southern Norway

Lichenometric dating : a commentary, in the light of some recent statistical studies
This commentary paper discusses the relative merits of new mathematical approaches to lichenometry. It highlights their strong reliance on complex statistics. The A. proposes that the success of lichenometric dating over the past 50 years has

Lichenometric dating of landslide episodes in the Western part of the Polish Flysch Carpathians
This paper presents the basics of lichenometry as well as its applications in geomorphological research. Also presented are results of lichenometric dating of landslide-rockfall walls in the western part of the Polish Flysch Carpathians. The study

A new lichenometric dating curve for southeast Iceland
This study uses 9 reliably dated surfaces covering the last 270 years within southeast Iceland to construct a regional lichenometric dating curve. The growth of lichen species within Rhizocarpon Section Rhizocarpon is non-linear over time

Replication of lichenometric data: errors associated with variations in operator search efficiency

Lichenometric dating of little Ice Age glacier activity in the central British Columbia Coast Mountains, Canada
The Little Ice Age behaviour of glaciers in the central British Columbia Coast Mountains was described by conducting lichenometric surveys of Rhizocarpon spp. found on recently deposited moraines in the Kitimat and Pacific ranges. The timing

Enhanced rockfall activity during Little Ice Age : further lichenometric evidence from a Norvegian talus

School children (age between 6 and 16 years) participated in an air pollution survey in the Brussels region. The lichenometric method used shows that air pollution, especially SO2 pollution, influences lichen growth and development. A map
of the growth rate of the epilithic species Lecanora muralis was drawn for the greater Brussels area and compared with SO2 pollution in this area. The lichenometric method contributes to the general development and education of children. - (Les AA.).

Lichenometrical studies and dating of debris flow deposits in the High Tatra Mountains, Poland

Preliminary results from the lichenometric study of the Nautardálur rock glacier, Tröllaskagi, northern Iceland

Measurement and calibration of weathering processes and lichenometric investigations on a wave washed moraine, Badamalen, on the upper Norrland coast, Sweden

Lichenometric dating and tephrochronology of sandur deposits, Solheimajokull area, southern Iceland

Lichenometric dating of moraine ridges in northern Norway: some problems of application

Lichenometric dating of debris-flow deposits on alpine colluvial fans in south-west Norway

A lichenometric growth curve in the French Alps : Ailefroide and Veneon valleys; Massif des Ecrins

and lichenometric dating. Specific objectives are: (1) to estimate the extent of variability in the mean annual radial growth rate both around the thallus perimeter and through time; (2) to compare the growth rate with those of smaller lichens; and (3) to evaluate
the implications of the results for lichen longevity, lichen growth-rate models and lichenometric dating curves.
