Geochemistry of enclaves and host granites from the Nelas area, central Portugal
Silva, M. M. V. G.; Neiva, A. M. R.; Whitehouse, M. J.Tonalitic, granodioritic and monzogranitic enclaves occur in the Hercynian peraluminous porphyritic biotite granite and biotite-muscovite granite from the Nelas region. Some variation diagrams show linear trends, but others show dispersion. The enclaves generally have closely similar isotopic signatures to those of the host granites. They contain xenocrystic plagioclase with the same composition as phenocrysts ...
