ON THE GEOMORPHOLOGIC EVOLUTION OF THE GREAT COASTAL COASTAL CLIFFS OF NORTHERN CHILE.
Keywords:
Geomorphology, Northern Chile, Coastal CliffsAbstract
About the geomorphic Evolution of the high Cliff along the arid coast of Chile. The marine Cliff of northernmost Chile, about 700 m high and 800 km long, represents a major geomorphic feature of the Earth. North of Iquique, it is still an active Cliff retreating under wave action but elsewhere it is an abandoned Cliff with a wave cut Platforro lying at its foot. The high Cliff probably derives from important Fault Scarps of Upper Miocene age which have retreated during a major Middle to Upper Pliocene Transgression. It has been only slightly modified by glacio-eustatic oscillations of Sea level during Quaternary times. Persistent aridity in spite of some more humid periods also accounts for its good preservation. There is evidence supporting a post Pliocene Subsidence of the coastal Area.
