On the association of Magmatic Microgranular Enclaves (MMEs) and cordierite-bearing monzogranites at the Sierra Bermeja Pluton (SW Spain)
Magmatic Microgranular Enclaves (MMEs) included in the cordierite-bearing monzogranites of the Sierra Bermeja Pluton (southern 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 composi...

| Sumario: | Magmatic Microgranular Enclaves (MMEs) included in the cordierite-bearing monzogranites of the Sierra Bermeja Pluton (southern 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 geochemistry, point to a separate origin for the MMEs and host monzogranites. 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 geochemical characteristics of the latter |
