ROUTE 2 WAYPOINT 6

 Waypoint 6: The change after the reef.  (Map Route 2)

After the limestones with abundant rudists, we pass to a soft unit (no relief) followed by some very altered limestones, without fossils, (just where the stands are) and above a unit of hard dolomites without hardly any structure, without fossils but with geodes.

Soft section: it hardly outcrops, except at this point. Specimens of Vaccinites giganteus can be seen at some points.

At the point where the stands are located, the contact between the nodular limestone unit and the massive dolomites that can be seen in the eastern part of the municipality and thanks to which the canyon of the La Hoz stream is formed can be seen.

RUTA 1 PUNTO 1 Y RUTA 3 PUNTO 18

Punto 1: Las Margas iniciales  (Plano Ruta 1)   (Plano Ruta 3) En este punto se observa la primera unidad blanda de la secuencia sedimentaria que forma DS-2. Esta unidad representa  hasta los primeros estratos que dan cierto resalte al cortejo TST, es decir Transgresivo, asociado a una rápida subida del nivel del mar lo que da una rocas de origen marino relativamente profundo. La primera unidad dura que da un ligero saliente mayor representa la superficie de máxima inundación (MFS). A partir de este nivel la tasa de subida del nivel del mar se desacelera haciendo que se vea compensado por el aporte de sedimentos hasta que inicia el cortejo de alto nivel del mar (HST). Paleontológicamente en esta unidad destacan unos ostreidos de gran tamaño, con una valva inferior muy pesada que le permite estabilizarse en el sustrato. Tras la muerte del organismo suele ser colonizado por esponjas y Serpúlidos. También es frecuente encontrar Ammonites como Prionocycloceras iberiense , Tissotia Sp. ,

ROUTE 3 WAYPOINT 17

Waypoint 17: Ochre Dolomites (Route 3 Map) At this point it is possible to find the ochre dolomites seen at point 8 again, although the quality of the outcrop is somewhat worse. We can see how it is made up of red dolomites formed by small oolites. All of them are associated with the moment when the sea level began to rise, but still with a low water level.

ROUTE 3 WAYPOINT 8

Imagen
Waypoint 8: Ochre Dolomites (Route 3 Map) From this point we can see a small farm with roe deer, but the presence of a unit of ochre dolomites is particularly noteworthy from a geological point of view. The relevance of this unit is that it marks the beginning of the stratigraphic sequence that contains the main geological elements of interest in the municipality. This unit marks a period of low sea level with almost aerial exposure of the sediment, which generates oxidation and gives these ochre colours.
