Elemental profiles were studied in thalli of a representative of Circinaria from Bogdinsko-Baskunchakskiyreserve (Astrakhan region, Russia). The highest concentration of iron, silica and aluminium were found in the cortex ofthe thalli. In the deeper layers the concentration of the elements decreases but the concentration of aluminium does notdepend on the depth. Iron and aluminium in thalli may act as filters for UV-B as well as heat insulators.
