An statistical study based on chemical components from the four outcrops of lamproitic rocks and correspondent loóse materials from Jumilla (Murcia province) is carried out in this work. Our results confírm that whole materials are chemically homogeneous. By means of the t-Student statistic we note significative differences essentially in SÍO2, TÍO2, AI2O3, and KjO contens between these volcanic outcrops. Also, they are direct lineal correlations in rocks for NiO-MgO and inverse lineal correlations for Na^O-KjO and CaO-MgO components. In loóse materials exists a lineal correlation principally for FcjOj-MnO. These resuls are congruent -ith the magmatic evolution proposed for the ultrapotassic rocks in this región by Venturelli et al. (1984).
