Based on the results of over 35 published studies, lichenometry has been widely applied in Iceland, proposing numerical ages absolute dating and relative ages relative dating of different surfaces.

The technique takes advantage of the radial development of the thallus on the rock, specifically the species within the Rhizocarpon subgenus, and has been applied in Iceland as dating as in other cold environments Golledge et al. Scott Bailey, Hannah L.

Gravestones and farm ruins that have been used in Iceland are moreover located several kilometres away from the geomorphic landforms that are investigated, and most often located at lower altitude, implying a different environment that do impact the lichen growth.
