The REE content and patterns, the Zr/Sc and Th/Sc ratios, and the high contents of Hf and Zr point to a felsic upper crustal source with a high degree of recycling. The Silgará Schists were metamorphosed at peak conditions of 670 - 770° C and 7.8 - 11.3 Kbar as indicated by the paragenesis Bt + Grt + St + Qz + Ky + Pl. The lithology and P-T conditions of the Barrovian type metamorphism of the Silgará Schists of the Silos stripe is very similar to those from the Mutiscua area. 2019 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49662418032 https://www.redalyc.org/journal/496/49662418032/ https://www.redalyc.org/journal/496/49662418032/html/ https://www.redalyc.org/journal/496/49662418032/49662418032.epub https://www.redalyc.org/journal/496/49662418032/movil 10.15446/dyna.v86n209.75648 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.209 Vol.86 |
