Resumen

In order to constraint geochemical differences related to the petrogenesis of the Ronda peridotites, major and trace elements combined with chondrite normalized REE patterns of the Sierra de Aguas Massif peridotites, near Carratraca (Málaga), have been compared with the similar published data from Sierra Bermeja Massif. The results establish a well geochemical distinction between previously petrographically identificated granular and porphyroclastic domains. The analyses also confirm that granular peridotites represent a more depleted mantle source than the porphyroclastics, apparently related with a fractional equilibrium melting process. Nevertheless, "U-shape" REE patterns and some REE ratios point to a more complex formation process.
