CONTINENTAL SEDIMENTARY BASIN ANALYSIS

Strategic Area:
Introduction:

The group has become a consolidated reseach group, named by the Aragón Government, since 2002 to present.

The research group nucleated in 1980. Since that moment, the principal research projects have focused on the analysis of Cenozoic and Cretaceous basins of Northeast Iberia. The analysis of these basins has been carried out by means of the “Tectosedimentary analysis”, a methodology that allows to divide the basin fill into allostratigraphic units and interpret the basin evolution in terms of allocyclic factors. This methodology has been used to cope with different environmental issues (e.g., paleoclimatic, hydrogeologic, geologic reservoirs), by using different tools: geochemistry, mineralogy, palynology, microbiology, geophysics, paleomagnetism, mathematic modelling and geostatistics, among others. The research interests have then diversified following several focuses, and the group has become a multidisciplinary group.

Our prime objective is the study and analysis of continental sedimentary basins as archives of the paleogeographic and paleoenvironmental evolution, with special focus on the controlling factors, such as climate and tectonics.

Research Lines:

Sequence stratigraphy in continental basins.

Sedimentology and Climatology of continental deposits (ancient and modern)

Hydrogeology

Background:

Study of Pleistocene and Holocene fluvial and aeolian deposits in the Ebro Basin (NE Spain).

Characterization of oil reservoir analogs at outcrop scale.

Sedimentology and geochemistry of fluvial and lacustrine carbonate systems (Mesozoic to present).

Sequence stratigraphy of the Teruel basin: basin model

Magnetostratigraphy of fluvial and lacustrine sequences. High resolution correlation.

Analysis of climatic periodicity in early Cretaceous to Holocene sequences.

Study of the climatic evolution during the Oligocene-Miocene and Miocene-Pliocene passages.

Study of climatic and hydrogeologic factors that have influenced the sedimentation of lacustrine and fluvial systems since the late Pleistocene in the Iberian Range.

Hydrogeologic modelling
