Objectives
Provide basic training for the characterization of the major mechanisms involved in formation, subsidence, and filling of sedimentary basins and also to develop a solid understanding of the major structural, tectonic (including convergent, divergent, and strike-slip domains), and geophysical processes that produce sedimentary basins. Importance for the research of natural resources.
Subject matter
Theoretical
1 - Introduction to basic concepts for the analysis of sedimentary basins; eustatism, subsidence, source and destination of sedimentary material, accommodation space, sedimentary balance, basin colmatation, base and breakup unconformity.
2 - Interplay between basin analysis and different thematic areas of Earth Sciences: Paleontology, Stratigraphy, Sedimentology, Petrology, Structural Geology, Geophysics.
3 - The Wilson Cycle. The formation and evolution of sedimentary basins related to diferent models of buildup and evolution of the continental margins.
4 - Classification and analysis of sedimentary basins in the framework of plate tectonics: a) criteria for classification; b) triggering lithospheric mecanisms; c) evolution of sedimentary basins in extensional, compressional and transcurrent tectonic environments; d) tectonic inversion; e) evolution of sedimentary environments and the sedimentary record.
5 - Syn-sedimentary and post-depositional deformation structures as markers of inner or outer basin dinamics.
6 - Paleogeographic, paleotectonic and paleoclimatic reconstructions. Criteria and methods
7 - Main economic resources in sedimentary basins: hydrocarbons, coal and water. Basin characteristics for traps and reservoirs and for exploitation of economic resources or the selection of wasting sites.
Practical
Interpretation and exercises on geological maps with sedimentary contexts. Drawing of simplified paleogeographic maps.
Field trips, visits to exemplary outcrops to illustrate de evolution of sedimentary basins in different tectonic contexts.

Teaching method
The teaching, supported in the use of multimedia projections and e-learning methods (use of the Moodle program) will include theoretical and practical lessons. In practical classes students will make the interpretation of geological maps including selected geological profiles.
The practical assessment will have a continuous component by the presentation of reports related to each map they interpreted, as well as the evaluation of the field books made during the field trips. Concerning the theoretical component, each students will make an oral presentations of a selected theme developed by consulting books and journals of the specialty and a final exam.
