Summary

Present-day and Neogene fluvial carbonates of Central Spain allow us to describe several petrological types: (a) spring and waterfall carbonates in wedge-shaped tufa buildups with moss tufa and karstification features, (b) water flow carbonates: encrustation tufa on plants (vertical tube facies and crossed tubes facies) and related detrital forms are shown. The stromatolitic buildups genetically associated with blue-green algae colonization on hard- or coarse-grain bottoms are also described. The blue-green algae colonization of erratic objects leads to the formation of oncolites (high-density colonization) or oolites (low-density colonization?). The biological data and the textural and structural properties of these carbonates are compared with other similar Tertiary and present-day carbonates. The Upper Neogene fluvial carbonates of the Madrid basin allow us to develop a distribution model of water flow carbonates.

Finally, a conceptual genetical model of fluvial carbonates is proposed. The main factors that influence carbonate features are: environmental energy, colonization morphology by blue-green algae and water properties.
