Recommended route.
This stop is reached via some steps that lead down from the main street.
We are at the base of the fault

The rocky materials, breccias and limestones of the Upper Triassic (between 208 and 200 Ma), and possibly of the Lias (Lower Jurassic, between 200 and 174 Ma), have been forced over grey marls of the Lower-Middle Miocene (Tertiary, 16 Ma ago). Due to friction, the surface of the rock that has served as contact is polished, producing what is known as a fault mirror.

At Cala Clara itself (point B) we see the same grey marls again. They correspond to the Banyanbufar Formation and have been formed by successive avalanches of materials in underwater slopes, usually caused by tectonic activity. This type of deposits is called turbidites.

In the coastal zone, and as occurred at Cala Molins, these turbidites are partially covered by ancient lithified dunes composed of calcarenite rocks, in which it is easy to see the cross-stratification, which is typical of this type of sediments.
