dc.description.abstractRecent sedimentation in the Lagunas de Villafafila is dominated by fine-grained sllicidastic deposits mainly composed of quartz, feldspar, muscovite, illite and kaolinite. Sediments are clay, clayey silts and clayey fine sands with sparse pedogenic carbonates and organic matter. The recentmost sediments contain diatoms and carbonates with bacterial features. Their structure is composed by parallel lamination, sometimes inclined by adaptation to bottom topography, and erosive surfaces. Rootlets are common to the top. Layering, textures and sedimentary structures reflect energy changes in the hydrological regime mainly related to water incomes from nearby areas. Although saline eflorescences are known to be generated since several millennia ago, saline layers and minerals are rare in the coresen_US
