Caleta Herradura Formation (Chile)
Caleta Herradura Formation (Spanish: Formación Caleta Herradura) is a geologic formation of Late Miocene (Montehermosan) age, cropping out on the Mejillones Peninsula in northern Chile. The erosion at the Coastal Cliff of northern Chile have created particularly good exposures of Caleta Herradura Formation. The formation deposited in a half graben within Mejillones Peninsula. The formation rests nonconformably on the Jorgino Formation.[1]
