Quebrada del Carrizo Metamorphic Complex is a geological complex of metamorphic rocks that crops out in Quebrada del Carrizo creek next to Cordillera Domeyko in Atacama Desert, Chile. Quebrada del Carrizo Metamorphic Complex is part of a larger accretionary complex in northern Chile that was an active accretionary wedge in the Late Paleozoic.[1]

Most of the complex is covered by the Miocene welded tuffs of Llano Las Vicuñas ignimbrites. The sedimentary protolith of the formation sedimented in the Late Paleozoic. The protoliths sediments arrived from the east with some lesser amounts arriving from as far as the cratons of the interior of South America.[1]
