Sedimentología de los depósitos de carbonatos lacustres en la cuenca miocénica de Valencia-Lliria (provincia de Valencia)

Resumo

The Miocene basin of Valencia-Lliria is located in the Iberian area of the Valencia province. This basin was filled up with marine and continental deposits and among them predominate the lacustrine carbonates. In these carbonates seven faciès have been distiguished: white laminated limestones, pisolithic limestones, banded micritic limestones, limestones with algal reefs, micritic limestones with gastropods, calcareous breccias and laminated oolithic limestone. These faciès appear associated to each other and are organized in shallowing - upwards sequences. Most of the deposits of these faciès are organic carbonates sedimented on the platform and slope of a permanent freshwater lake. The ciclicity of these deposits is the result of changes in the lake water - level which were recorded in the platform sediemnts
