Geoquímica del Boro y Elementos Incompatibles en el Granito de Nisa-Alburquerque
In the Peraluminous Nisa-Alburquerque granite we have study the Boron and incompatible elements (Rb, Li, Cs, Be, Sn, U) contents. Despite scatering, these elements show an increase from monzogranites towards leucogranites and aplites. Leucogranites and aplites with roughly the same differentiation i...

| Resumo: | In the Peraluminous Nisa-Alburquerque granite we have study the Boron and incompatible elements (Rb, Li, Cs, Be, Sn, U) contents. Despite scatering, these elements show an increase from monzogranites towards leucogranites and aplites. Leucogranites and aplites with roughly the same differentiation index show very variable contents in B and incompatible elements. We propose that variability in monzogranites could be due to inherited compositional hetereogenities from the protolith, whereas the high variability in leucogranites and aplites could be due to late magmatic proceses such as hydrothermalism |
