Evolución sedimentaria reciente de las Tablas de Daimiel (Ciudad Real)

Abstract

Two sedim entary events have been distinguished in the recent evolu tio n o f the present Tablas de Daimiel National Park. The older one is characterized by the presence of siliceous sands and silts, and mudstones; the former contain fluviatile Pelecypods and Gastropods, being interpreted as channellized deposits corresponding to the last stage of the Holocene fluvial inclssion. The mudstones sometimes contain a high content in carbonate and/or organic matter, root debris and gastropods are also common; this sediments are interpretad as deposited in a muddy alluvial plain. Finally, the younger event is dominated by peat and lime mud sedimentation in a lacustrine-palustrlne system crossed by some fluvial channels
