View on the field area: Cap de Creus, where the Pyrenees reach the Mediterranean Sea


Cap de Creus is the easternmost point of the Pyrenees, just south of the Spain-France border. It is part of the central "Axial Zone" of the Pyrnees (a), which contains Precambrian - Paleozoic rocks, which were deformed and metamorphosed during the Palaeozoic Variscan Orogeny. The main field area (retancle c in fig. b) is located about 5 km away from the town Cadaqués. Precambrian-Ordovician meta-sediments are found there, with a high metamorphic grade (amphibolite facies, up to anatexis). Variscan magmatic rocks that occur are two large granite bodies outside of the mapping area and many small pegmatite bodies in the mapping area. The area is a Natural Park, because of its natural beauty, geological heritage and precious flora and fauna.

The rocks were deformed several times during amphibolite facies metamorphism. Later, shear zones formed during retrograde greenschist facies conditions. The aim of the field exercise is to map and unravel the complicated tectonic - metamorphic - magmatic history of the area. This can be done with the many structures that are exposed, such as cleavages, folds, quartz veins, boudins, pegmatites, porphyroblasts, etc. Outcrops are excellent!

The beautiful Cap de Creus peninsula attracts many tourists, especially the Pentacost-weekend. We will therefore also do some exercises away from Cap de Creus:

  • The Biure-antiform near Biure, about 30 km NW of Roses. Here we can "warm up" with a large-scale structure that formed during the Alpine Orogeny in Mesozoic rocks.
  • Shear zones on a coastal platform near Roses. Here we will see the Roses Granodiorite, which is cut by many shear zones.
  • An excursion along the coast East of Rosas, to see spectacular mega quartz veins, and low metamorphic grade rocks that were folded several times. The day ends at a nice beach with bar.

The results of the exercises will be presented in short reports and maps, which will be made during the field trip. 


On Friday May 25th, we will drive from Tübingen to Garriguella, just across the Spanish border. It is a long drive, so be in time on Friday morning! We  stay at the camp ground of Garriguella.

  • sheets of A4 drawing paper
  • transparent tracing paper for stereonets
  • ruler
  • calculator
Apart from usual clothes and personal items:
(please keep to a minimum to reduce luggage!)
  • sturdy field boots (the rocks are sharp)
  • sturdy trousers (thorny scrub)
  • wind-tight jacket (it can be VERY windy!)

Cadaqués is best known as the home town of Salvador Dalí, who ensured that Cadaques remained mostly untouched by big hotel developements
