Abstract:
The deterioration of carbonaceous rocks in urban areas can be roughly classified in three kinds of feature patterns visibly distinguishable on the rock surface. In this paper the three different kinds of deterioration are described and interpreted in terms of the principal mechanisms leading to their formation. The way liquid water controls both the rate and the morphology of the deterioration crust formed on the stone as observed in the field, indicates that local rainfall is a critical factor in determining the type of deterioration. It appears that the different weathering observed actually depends on the way the interaction of rain with the surface occurs, at one extreme a complete washout of the surface, to the other where the surface is only very slightly wetted.
