Resumen:
In this contribution, the basement of the southern sector of Sierra de Ambato is petrologically characterized along the Concepcion-Pomán section. The low-grade metasedimentary rocks (metapelites, metapsamites and quartzites) constitute the outcrops of greater extension. These sequences develop a penetrative metamorphic foliation with NNE-SSW orientation and high-angle dips to the WNW. High-grade metamorphic rocks are represented by migmatites, both metatexites and diatexites. It is tentatively determined that the metamorphic conditions for low-grade metasedimentary rocks would correspond to green schist facies, while for migmatites we indicate a metamorphism of high amphibolite to granulite facies conditions. The described low-grade rocks are linked with migmatites, generating complex contact relationships. The metapelites, metapsamites and quartzites could be correlated to the La Cébila metamorphic complex.
