Recent sedimentation in the Lagunas de Viffafafila is dominated by fine-grained siliciclastic deposits mainly
composed of quartz, feldspar, muscovite, illite and kaotinite. Sediments are clay, clayey sifts 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 paraffel laminatiun, sometimes
inclined by adaptation to bottom topography, and erosive surfaces. Rootlets are common to the topo
Layering, textures and sedimentary structures refleet 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, satine fayers and minerals are rare in the cores.
