TheChañaral Epimetamorphic Complex orLas Tórtolas Formation[1] is anaccretionary complex composed ofmetamorphic rocks located in westernAtacama Region,Chile. The rocks of the complex are mainlymica-schist,greenschist andmetasediment oflow-grade. The deposition of thesedimentaryprotoliths occurred in theCarboniferous andPermian being latermetamorphosed. Among the protoliths of the complex areturbidites and other sediments.[2] Chañaral Epimetamorphic Complex is thought to represent the shallow and frontal part of anaccretionary prism while the nearbyPunta de Choros Metamorphic Complex represents the deeper basal part of the very same accretionary prism.[2]
