Schwartzman contends that lichens and other microbes may significantly contribute to chemical denudation of exposed rock by their combined physical and chemical activity. Lichens do not generate a thick soil but they do stabilize already existing soil (cryptogamic). Studies on chemical denudation in soil-free alpine terrains may contribute to a better understanding of the microbial role in weathering since lichens and algae are commonly found on bare rock in these settings.
