The results of the organic matter analysis (low H/C ratio and predominance of even n-alkanes) together with the lack of pollen and micromammal remains as well as the abundance of charcoal particles, suggest the development of the first wild-fire in the Mediterranean realm, which affected the catchment area of the alluvial fan that fed the Cortes de Baza areaspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/PlioceneBiomarkersCPICHNGuadix-Baza Basinjournal articleopen access
