O Granito do Porto corresponde a um granito hercínico, leucocrata, de duas micas, fortemente peraluminoso. No presente trabalho foram realizadas análises para os sistemas isotópicos Rb-Sr e Sm-Nd, em cinco amostras frescas do granito em estudo. Obteve-se uma isócrona Rb-Sr de 306±7 Ma (MSWD=0,71; 87Sr/86Sr inicial=0,7128), que dentro da margem de erro, deverá refletir a instalação magmática. Em termos de geoquí...
