Resumen
Au in Ordovician and Silurian-Devonian meta-sedimentary rocks: it is located along the Eastern Cordillera of Peru. Host rocks area composed of slate and schist from the lower Paleozoic. Ore structures are composed of quartz-gold veinlets and lenticular layers maily controlled by NW-SE thrust faults. Ananea, La Rinconada, Capac, Orcco, and Untuca are among the main deposits. Upon latest surveys (Haeberlin, 2002; Chew et al., 2005; Cardona 2006), this belt would extend to the North (6°). This has been inferred from the fact that the Marañon Complex (6°-10°-30’) can be subdivided into three geological unit, according to its history the sedimentation and metamorphism: Lower Ordovician, UpperOrdovician-Silurian and Carboniferous. Precambrian ages only correspond to some isolated segments of migmatites (Cardona, 2006).
