AB Relict cllnopyroxenes from strongly altered basalts sampled in the Sotiel-Torerera area (central sector of the Iberian Pyrite Belt, southwestern Iberian Massif, Spain), have been analysed by EMP. It has been found that clinopyroxene cores are Ti-rich, representing the pyroxene compositions equilibrated with basaltic magma. An alkaline magma character is consequently deduced. Finally, it is suggested that data from relict minerals may indicate the original magma character better than whole-rock geoshemistry, in this and other cases in which rock alteration Is both intense and polyphased
