چکیده انگلیسی
The effects of biogeophysical and biogeochemical weathering generated by the epilithic lichen species Sporastatia testudinea (Ach.) A. Massal., Lecidea atrobrunnea (Lam. and DC.) Schaer. and Rhizocarpon geographicum gr. on antigorite serpentinites were examined with a petrographic and lichenological approach. Lithotype structure and mineral composition are decisive factors in modulating hyphal penetration which invades up to 2Â mm in depth. A microcrystalline fraction composed of fragments of the colonized substratum (antigorite, magnetite, diopside), neoformation minerals typical of serpentine soils (illite, halloysite, vermiculite) and biomineralization products (mainly oxalates), constantly found at the lichen-rock interface, underlines the important role of these crustose lichen species in the pedogenetic processes.
