Course Content

What’s here?

Deepwater turbidite channels, levee deposits and mass transport complexes of the Ainsa and Jaca basins (including core data).

Two regional scale fluvial systems
1) Eocene axial, thrust sheettop fluvial system;
2) Oligo-Miocene transverse fluvial system feeding into the Ebro foreland basin.

Tidally influenced sandstone bodies (Roda Sandstone) of the Tremp-Graus Basin.

Geological Theme and Course Content The region offers the ability to focus on a number of technical themes including:

The analysis and interpretation of the sedimentology, stratigraphic architecture and reservoir potential of alluvial fan, fluvial, tidal- and wave-dominated shorelines/shelves, and deepwater deposits.

The interpretation of a range of deepwater sandstone bodies from slope canyons, through basin floor channels to basin plain.

The analysis of regional scale sediment transport paths in terms of their reservoir potential, the controls that determine length scales of down-dip changes along the transport paths, and predictions that can be made in terms of reservoir presence and characteristics.

The relation between the spatial distribution of reservoir potential to the structural geometry of tectonically active basins in an exploration sense.

The differences between fluvial, shallow marine and deep marine depositional systems from a modelling perspective.

The evaluation of the use of outcrop analogue data for building better reservoir models and understanding reservoir zonation from a geological (rather than engineering) perspective (supported by outcrop-based models for development planning scenarios).

Access

Fieldwork is carried out in the foothills of the southern Pyrenees and on the Huesca Plain. Outcrops are partly road-side, in addition to quarries and hillside view-points. Access is by coach with short walks of up to 2 km over scrubby ground and rocky terrain can be expected. Participants should be aware that some localities are at an altitude of around 1000 m (3000 ft) and field temperatures may exceed 25 degrees celsius.

Logistics

Pyrenees, Spain: fly in/out Barcelona. Accommodation in Tremp, Ainsa and Ayerbe depending on outcrops to be visited.
