Magmatic Microgranular Enclaves (MMEs) included in the cor- dierite-bearing monzogranites of the Sierra Bermeja Pluton (sou- thern Iberian Massif) have been examined to elucidate their possible petrogenetic linkage. Mineralogical differences such as the absence of Crd and Kfs in the MMEs, or the compositions of Bt and Pl, as well as the lack of correlations of some elements in whole-rock geoche- mistry, point to a separate origin for the MMEs and host monzo- granites. The MMEs could represent minor globules of a more mafic magma injected into and comingled with the host monzogranitic magma, without causing significant modifications in the geochemi- cal characteristics of the latter.
