Field Trip Leader: Jaume Vergés
Limit: 20 Participants

The main plan of this fieldtrip to the South Pyrenean Fold Belt is to have an overview of a fold belt and adjacent foreland basin through four well-exposed and well-known localities. Each example permits the discussion of different geological processes related to the interplay between tectonics and sedimentation and the role of salt-tectonics during both pre-compression rifting and during tectonic inversion.

Day 1 - Sunday 5 September 2021

Stop 1: Overview of the southern margin of the Ebro foreland basin: Montserrat fan-delta

The main objective In the Montserrat fan-delta locality is to characterize the evolution of the southern margin of the Ebro foreland basin during the Pyrenean shortening with especial emphasis on its tectono-sedimentary evolution through the Eocene. The size and quality of this outcrop is directly comparable to good seismic examples.

Stop 2: Role of detachment levels and salt-tectonics in building the fold belt: Cardona diapir

The main objective in the Cardona diapir locality is to provide an overview of salt tectonics in compressional settings at different scales using the South Pyrenean examples. The role of pre- and syn-orogenic evaporitic levels during shortening in fold belts is discussed as well the interplay between tectonics and sedimentation.

Day 2 - Monday 6 September 2021

Stop 1: 3-D Growth strata to define folding mechanisms and growing topography: Sant Llorenç de Morunys

In the Sant Llorenç de Morunys locality. along the footwall of the Pyrenean thrust sheets, we can observe the 3-D views of the large-scale and best preserved growth strata worldwide; several square kilometres and more than 500 m of tectonic relief. The size and quality of this outcrop is directly comparable to good seismic examples.

Stop 2: Evolution and inversion of a salt-related rift basin: Roca Narieda

In the Roca Narieda locality we discuss the role of pre-orogenic salt tectonics in development of salt-related rift basins and their control on Lower Cretaceous platform growth. Outcrop is also superb and is directly comparable to good seismic examples.

Drive to Barcelona (2:30 hours)


In early-September the weather can be still hot or very hot and therefore it is recommended to bring fresh clothes, hat or cap and sunscreen as well as drinking water. Do not forget suitable hiking boots. If weather conditions are good we can walk on steep terrain for short distances (but only in two of the four localities).

Join a TIG

Fundamental and applied aspects of salt-influenced sedimentary basins from salt deposition to tectonics and dissolution. The ultimate goal of the Salt Basins TIG is to unite academia and industry, diversify our field (people and research topics), and to create a scientifically inclusive environment for leading experts in salt tectonics to collaborate and thrive.

Join a SIG

The function of the Visiting Geoscientist Program SIG is to provide college and university students worldwide a balanced picture of geosciences in the petroleum, energy minerals, and environmental industries; provide information about careers in the geosciences; present a positive image of a geoscience professional; and encourage geoscience career options for young scientists of high caliber. These goals will be achieved through direct student contact during college and university visits by active geoscientists. To maintain active status as a VG, each committee member must complete at least one visit per fiscal year. This program is funded through the generosity of the Visiting Geoscientists, their companies, the AAPG Foundation and AAPG.
