Mejillones Peninsula (Spanish: península de Mejillones) protrudes from the coast of northern Chile north of Antofagasta and south of the port of Mejillones.
The basement rocks of the peninsula are made of metamorphic and igneous rocks that formed in the Late Triassic plus plutons formed in the Early Jurassic.[1] The eastern part of the peninsula hosts various normal faults.[2] Extensional tectonics in the peninsula begun no later than in the Early Miocene and has resulted in the formation of two half graben basins. The uplift that the peninsula had in the Pliocene and Pleistocene has been attributed to subcrustal accretion in the subduction system.[3]

[es] Península de Mejillones
La península de Mejillones se ubica en el Norte Grande de Chile, entre los puertos de Mejillones y Antofagasta. A diferencia de muchas penínsulas, la de Mejillones es más ancha que larga adentrándose sólo alrededor de 20 km en mar,[1] mientras que su istmo que lo conecta con el continente de alrededor de 40 km de ancho. El sur de la península es atravesado por el Trópico de Capricornio.Другой контент может иметь иную лицензию.
