We evaluated the deposition rate of atmospheric dust in a non urban area of the Granada Depression (SE of Iberian Peninsula). By using in part existing methodology, we determined a rate of 23.06 g·m2·yr-1 on the basis of weekly observations, that showed marked variations, partially controlled by Saharan winds. The components of the dust can indicate source area. Thus, southerly winds provide considerable allochthonous components from North Africa, while others are local. Despite the scarcity of industrial activity, signs of contamination were recorded. The employed methodology complements the work methods used by other researchers.
The role of airborne sediments provides an illustration in soil genesis of the Mediterranean region.
