Nuevas aportaciones a la caracterización geomorfológica del Manto Eólico Litoral de El Abalario-Doñana: el perfil de la laguna Río Loro (Huelva, España)

Abstract

The RLO-ZC profile of Río Loro small lake at El Abalarlo area in MELAD (Aeolian Littoral Sand Sheet at El Abalario-Doñana), in Doñana Natural Park (Huelva, Spain) has been studied from a weathering point of view. We can identify two units in this profile: the below of these constitutes one sandy-clayey removed deposit from Pleistocene, where quartz is predominating in sands and kaolinites in the clay minerals. The superior unit is a sandy-clayey deposit ofaeolian and pooled character from Pleisto-Holocene or Holocene with quartz, high level smectite content and low level kaolinite proportion. Finally, the study provides a new interpretation to the geomorphologic model of MELAD in El Abalario area
