Trapa-Trapa Formation
Trapa-Trapa Formation (Spanish: Formación Trapa-Trapa) is a volcano-sedimentary formation of Miocene age in south-central Chile and nearby parts of Argentina. The largest outcrops lie in the Andes, while the Chilean Central Valley host some of the smaller outcrops. The volcanic rocks of the formation are of calc-alkaline character, and are less silicic than contemporary volcanic rocks found further north in the Farellones Formation.
