During the Plio-Pleistocene transition, progressive cooling of the Earth and tectonic processes related to the Andean orogeny modified oceanic and climatic conditions in the Southeast Pacific. This would have generated changes in sea surface temperature, terrigenous input, and oceanic productivity in the Humboldt upwelling system. The present project aims to contribute with the characterization of the environmental and sedimentary conditions during the Plio-Pleistocene in the central-southern Peruvian continental margin (16º S), where there is currently an upwelling cell, through lithostratigraphic, granulometric, chemostratigraphic and isotopic analysis. Therefore, the processes of terrigenous input, marine productivity and oxygenation in the ocean floor were characterized through the analysis of Plio-Pleistocene sediments of the Caracoles Fm. at the Cerro Amarillo locality. These analyses suggest the existence of a high-energy shallow-marine environment with major aeolian influence, with slight facies variations, during the sedimentation of the Caracoles Fm. In addition, it is possible that remineralization processes and terrigenous input were different from those during the sedimentation of the Pisco Fm.
