Title: Origin of sand dunes in the Copiapó region, Atacama Desert, Chile.
Abstract: Extensive areas of active dunes are found in the Copiapo region. However, their sand supply is presently depleted. It has been proposed that deflated uplifted marine terraces of the coastal belt between the Copiapo River and Caldera were the source of the dune sand. Such a hypothesis is not supported by sedimentologic data, which suggest a fluvial origin for the aeolian sands. They could be related to Neogene alluvial accumulations built up at the mouth of the Copiapo River and the ephemeral streams located to the north of it.
