Description
Apenas está disponível o resumo da comunicação. The lower Ordovician medium-grained biotite of 479-480 Ma predominates in the Oledo-Idanha-a-Nova pluton and is deformed. It contains different biotite tonalitic and biotite granodioritic microgranular enclaves concentrated on the pluton’s west part. Microgranular enclaves and host biotite granodiorite are I-type granitic rocks and contain amphibole, sphene, allanite, ilmenite and magnetite.
