R.5. From Aínsa to El Pueyo

Route 5. Aínsa - St. Anne’s Hermitage - El Pueyo de Araguás - Soto - Buixitar - Aínsa

The first point of interest is the submarine channel of the turbidic system in Aínsa II, whose evolution and structure has been studied by universities and crude oil geologists world-wide. In the following outcrop, sandstones and marlstones show different resolutions as a result of tectonic forces.

Sandstones are broken, whereas marlstones absorb the deformation with a more ductile behaviour.

Later, the track crosses some sandstone layers with sea urchin fossil traces that formed as they were feeding.
The final point shows us a diversity of aspects in the sandstone layers in the turbidites, from their thickness to the variety of texture and structure. .
