Edad de enfriamiento U/Pb en rútilos del Gneis de Chímparra (Cabo Ortegal, NO De España)
The Chfmparra gneisses are characterized by a HP-HT (800°C, ISOO MPa) mylonitic fabric reequilibrated under amphibolite facies (600°C, 900 MPa). This fabric is formed by Qtz+Plag+Bt+white mica + Grt+Ky. Rutiles are preserved as inclusions whithin garnet. These rutiles have been dated at 382+1-3 Ma C...
