(2007) - Geochemistry and petrogenesis of biotite granodiorite and its microgranulares enclaves from Oledo-Idanha-a-Nova pluton (Central Portugal). In Congresso Ibérico de Geoquímica, 6, Vila Real, 16-21 de Julho - Livro de resumos = Abstracts book. Vila Real : UTAD. p. 77. Comunicação.http://hdl.handle.net/10400.11/760Apenas 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.engMicrogranular enclavesFractional crystallizationMagma mixingDeformationOledoIdanha-a-Novaconference object
