Abstract

The aim of this paper is to investigate the rate of biological weathering in the earlier stages, on more recently exposed surfaces, including moraine ridges that were deposited by the glacier in the 1980s and 1990s. This study demonstrates the reduction in Schmidt hammer R-values that followed the rapid colonization by this endolithic lichen of pyroxene-granulite boulders on terrain deglaciated over the last 88 years on the Storbreen glacier foreland, Jotunheimen. The rapid rate of biological weathering reported in this study itself offers possibilities for a new method of phytometric dating for very young rock surfaces
