| Sumario: | The Lower Cretaceous series of the northern side of the "Páramo de la Lora" is mainly continental fluvial. A detailed analysis of the section outcropping between Cuillas del Valle and Olleros de Paredes Rubias, has revealed fades which can be attributed to transitional continental-marine enviroments. These are horizontally bedded sandstones with oscillation ripples (lagoon and shoreface), and cross-stratified sandstones with backset laminae (tidal). Other cross-stratified sandstones (fluvial channels), laminated lutites (alluvial coastal plain), bivalve sandstones (tidal ?) and lutites with leaves (marsh), make up contemporaneously-related subenvironments. Storm wave action prevailed during the filling of a narrow erosional depression, and tidal action accompanied the later establishment of valleywide sedimentary conditions |
