Shelf and Terrestrial Clastics and Carbonates in the Cantabrian Mountains, Spain

Course Description:

The Cantabrian Mountains of Northern Spain are known for their spectacular outcrops of Palaeozoic clastic and carbonate rocks. From the Cambrian to the Upper Devonian, calcareous sediments were deposited here in relatively shallow water on the continental shelf. Trilobites, corals and brachiopods are all in evidence. During the Variscan Orogeny in the Carboniferous, this region underwent a transition from marine to continental sedimentation. Strike slip tectonics exerts an influence on sedimentation patterns during the late Carboniferous, resulting in the preservation of a thick succession of clastic sediments deposited in a variety of continental environments. A well preserved palaeotopography with deeply incised palaeovalleys preserves proximal red bed alluvial fan and fluvial deposits. Coal beds and lacustrine sediments also abound in this part of the succession, indicating warm, humid climate conditions with an abundance of vegetation.

This field trip can also be delivered in conjunction with our courses on Clastic Reservoir Geology or Carbonate Reservoir Geology.
