Quaternary Science Reviews, 2015 Abstract Lichenometry is a straightforward and inexpensive method for dating Holocene rock surfaces. The rationale is that the diameter of the largest lichen scales with the age of the originally fresh rock surface that it colonised. The success of the method depends on finding the largest lichen diameters, a suitable lichen-growth model, and a ...

Lichenometric dating (lichenometry) and the biology of the lichen genus rhizocarpon: challenges and future directions [PDF]
Geografiska Annaler, Series A: Physical Geography, 2016 Lichenometric dating (lichenometry) involves the use of lichen measurements to estimate the age of exposure of various substrata. Because of low radial growth rates and considerable longevity, species of the crustose lichen genus Rhizocarpon have been the most useful in lichenometry.

Studies on the growth of rhizocarpon geographicum in nw scotland, and some implications for lichenometry [PDF]
Geografiska Annaler, Series A: Physical Geography, 2010 Scotland, a maritime subpolar environment (55–60°N), has seen relatively few applications of lichenometry – even though it offers much potential.

‘Growth rings’ in crustose lichens: Comparison with directly measured growth rates and implications for lichenometry [PDF]
Quaternary Geochronology, 2015 Some species of crustose lichens, such as Ochrolechia parella (L.) Massal., exhibit concentric marginal rings, which may represent an alternative technique of measuring growth rates and potentially, a new lichenometric dating method.

A Bayesian hierarchical extreme value model for lichenometry
Environmetrics, 2006AbstractCurrently, there is a tremendous scientific research effort in the area of climate change. In this paper, our motivation is to improve the understanding of historical climatic events such as the Little Ice Age (LIA), a period of relatively cold weather around 1450–1850 AD. Although the LIA is well documented in Europe, its extent and timing are
