The Sierra de Comechingones is located in the southwestern part of the Sierra de Córdoba. It is an eastern tilted block of crystalline basement limited by high‑angle reverse faults. The central‑eastern area is composed of medium to high grade metamorphic rocks: gneiss, schists, and migmatites; and minor anphibolites and marbles. Mineral assemblages of the metapelites are Bt + Grt + Sil + Kfs and Bt + Grt + Crd + Kfs. Chemical analyses of major elements suggest that the parent rocks were granodiorites from the peraluminous calc‑alkalic series and  minor pelites.
