Description :
In this paper, new indices of rock surface weakening (IRW) and the rock surface weakening rate (WR) are defined in relation to Schmidt hammer mean R-values for gneiss and peridotite. The methods and results are evaluated, particularly in relation to previous research and other rock types in Scandinavia. The various indices, being affected in different ways by biochemical and biological mechanical weathering and micro-erosion, are regarded as complementary aids in the investigation of both the effects of chemical weathering and its rate.
