Fungal filaments are the most abundant organic features in weathered profiles developed on chalky limestone ("platy calcrete"). Their activity affects the mineral dynamics of the pore/carbonate microsystem. A theoretical biogeochemical model is proposed to describe the Ca-oxalate-carbonate cycle related to fungal activity in dry environments.
