ROUTE 1 WAYPOINT 17

Waypoint 17: The upper area Map route 1

We reach the highest point in the route, at 1090 metres. Here we can appreciate how the rocks flourish nearby. We cannot see any fossils or even structures, we just see the dilution of carbonatic rocks due to waterflow. It is also remarkable the absence of vegetation due to agricultural and cattle farming in this zone.

In the surroundings you can see rock fences that have been built with rocks of the area, this is because traditionally, these fields were cultivated even though they were quite rocky, which implied that first it had to be cleaned and pulled of as the field was ploughed.

ROUTE 2 WAYPOINT 11

Waypoint 11. "Tapiology" the geology and its environment   (Map Route 2) This wall has been built using different rocks of its surroundings, we can practically indicate in a clear way, where all or almost all the rocks that form it have come from. If we look in detail we see several rocks with the already classic rudists, (these tubes or circular holes in the rocks). We find here rudists of diverse origin and typology, which allows us to make a review of the regional paleontology. 1) Hippurites incisus : characterized by its irregular morphology with two very marked partitions in the shell which generates two large wrinkles in the interior space. 2) Biradiolites canalictus : rather thin in diameter and long, they stand out for not having these inner pillars, but nevertheless have a very thick and folded shell. 3) Radiolites sauvagesi : of large diameter without inner pillars, and very thick shell with different overlapping lamellae; which gives an external appearance of "

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.

RUTA 1 PUNTO 1 Y RUTA 3 PUNTO 18

Imagen
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. ,
