The formations of the Morro Solar Group are: La Herradura Formation (Spanish: Formación La Herradura), whose sediments reflect a marine near-shore deposition environment,[4] the Valanginian Salto del Fraile Formation (Spanish: Formación Salto del Fraile), and the Marcavilca Formation (Spanish: Formación Marcavilca).[1] The Salto del Fraile Formation is equivalent to the basal part of the Huancané Formation found further inland.[5]
