ROUTE 1 WAYPOINT 14

 Waypoint 14: A cave thanks to a fault Map route 1

Inside this same unit we find a cave with a peculiar triangular shape, with one of its' sides really flat. It is a small inverted fault with a movement of a few centimetres.

These faults of small size are easy to see, differently to the bigger one that generate big movements which are produce a big deformation making it difficult to see.

It is outstanding that if we enter the cave, the flat wall has a slightly different colour, with a little glow, this is called fault mirror. When the rock moves during earthquakes, sand grains file and polish the break zone, in some cases (not here) it can causa an increase of the temperature and even a partial meltdown. The different grains and the faults' movement generate grooves and even small steps that help us deduct the movement of the fault.

ROUTE 1 WAYPOINT 8, ROUTE 2 WAYPOINT 4 AND ROUTE 3 WAYPOINT 4

  Waypoint 8: The reef. (Map route 1) (Map route 2) (Map route 3) We arrive at what it may be the most important waypoint of the route, the Sistine Chapel or the Sancta sanctorum of Castrojimeno Village. Here we arrive at the reef itself, what corresponds to the facies C and D (already described previously), where we see the sucession of fossils that are substituted eventually, depending on the dynamic conditions, in particular Radiolites Sauvagesi, Hippurites Incisus that are really close which are substituted with clustering of Biradiolites angulosus, Radiolites Sauvagesi and Hippurites incisus. As we have mentioned, this sucession is the reef itself in different zones of the barrier and with small variations generated of storms or the different positions that conform the barrier of the reef. The most interesting parts of this point are not only the fossils, that present a perfect state of conservation, but also the detailed analysis of the suecssion of fossils and the strata that

ROUTE 1 WAYPOINT 12

  Waypoint 12: The meeting point rock      Map route 1 As we move on, we continue with the unit of Dolomites of Montejo. Here wwe can see similarities with waypoint 3 but increased in magnitude. If we saw previously eroded ground and diluted by water, here the effect is larger, generating big, well-formed exokarstic structures. It is outstanding the rock just in front of us, the meeting point rock, symbol of Castrojimeno. Here two paths meet (right and left) and that continue in the path we have been following until this point. This structure called "Tor" has remained isolated, even though a few metres away we can find similar structure of smaller size. It represents an isolated block of the large dolomitic unit were we find ourselves. Another curious fact is that if we take notice of the position of the strata, they are slightly tilted, more than the rest, which determines that this is possibly a dumped block or partially rotated.
