COURSE CONTENT:

Day 1

  • Arrive in Barcelona
  • Meet at 18.00 for introductions

 

Day 2

  • Travel from Barcelona to Ainsa (4 hours with 30-minute comfort stop half way)
  • Ainsa is located in the south-central Spanish Pyrenees. Ainsa is situated at the confluence of the Rio Cinca and Rio Ara, with spectacular views of the surrounding countryside and mountains including the high Pyrenees. Ainsa has a 12th-century church (Iglesia parroquial de Santa María, consecrated in 1181), an 11th-century castle (with a visitor centre, geological and ecological museums in the restored fortifications), and Placa Mayor dating from the 12th century that is surrounded by Medieval buildings, including restaurants, bars and souvenir shops. The old town provides an opportunity for sightseeing.During the 8th century the part of Aragón with Ainsa marked the northern limits of Al Ándalus. It is still disputed if Aínsa itself fell to the Moorish invaders, but many key battles were fought in the nearby hills. According to legend, in 724, the Christian troops, under King Garci Ximenez, were inspired to victory over the Moorish armies by the appearance of a burning cross above a holm-oak tree. In the fields behind Ainsa castle, there is village, a stone shrine (the Cruz Cubierta) that marks the spot where the vision is said to have occurred. The symbol of Ainsa is a burning oak tree.
  • Panoramic viewpoint from Guaso church. Orientation, introduction to Ainsa Basin (Middle Eocene deep-marine sediments) and its tectonic context within the Pyrenean orogen

  • Ainsa Quarry ~ 1 km south of Ainsa to look at spectacular outcrops with a large range of sedimentary facies and depositional architecture
  • Forcaz Stream, Ainsa II sandbody (fan) and associated thin-bedded deposits, plus Well Labuerda 2. (time permitting)
