Abstract(s)

Phosphate minerals are common in northern and central Portuguese granitic rocks. Childrenite, eosphorite and intermediate compositions in this solid-solution séries occur in muscovite granites at Paredes da Beira and Penamacor-Monsanto, muscovite-biotite granites at Penamacor-Monsanto and in aplite veins at Vidago. The composition of childrenite and eosphorite are similar in each of these localities. Germanite occurs in a muscovite granite at Segura.
