Prerequisites
It is a subject with a marked integrating character and synthesis of all the disciplines involved in sedimentary geology, emphasizing the stratigraphic interpretation of the subsurface. It is aimed at understanding the formation mechanisms of different types of sedimentary basins, as well as the characterization of their infill. It is therefore highly applicable to projects with economic objectives, mainly resource exploration (energy or water), as well as mitigation of the effects of climate change (identification of possible CO2 storage in old reservoirs or saline aquifers).
It is assumed that students have acquired the basic knowledge of various branches of fundamental sedimentary geology in previous courses, and mainly stratigraphy, sedimentology and tectonics.
Objectives and Contextualisation
This course aims for students to gain knowledge of the dynamics of sedimentary basin formation and their infill, and to know how to organize their deposits from a sequential stratigraphic point of view. During the course, practical exercises will be carried out to value the integration of different methods of study of surface and subsurface geology. It is therefore a subject in which students are faced with techniques for obtaining data of various types and their geological interpretation. These data and interpretations will be aimed at understanding their application and potential to achieve economic, protection/conservation, or climate change mitigation objectives.

Methodology
1. Managed activities
Theory sessions
This course consists of a theoretical part, with interactive classes in which the proposed syllabus will be explained and discussed, and guidelines will be given so that students can complete learning independently. The students will have the theory agenda in the form of presentations (in .pdf) and a bibliography recommended by the teaching staff on the Virtual Campus.
Laboratory practices and seminars
They will basically consist of carrying out exercises related to theory classes, and mostly focused on practical work on seismic reflection or satellite images. The exercises will be assisted by the teaching staff, who will solve problems of a general nature that will be discussed among all, as well as specific problems. The basic material is from real cases and the exercises must be delivered at the end of the practice or through the Virtual Campus at the end of the week where each exercise is worked on.
2. Supervised activities
Original work of synthesis on (1) sequence stratigraphy of a type of depositional environment or (2) an example of sedimentary basin
2a) Elaboration in groups of two students of an original work of synthesis on (1) sequence stratigraphy of a type of depositional environment or (2) a real example of a sedimentary basin. There will be a series of topics proposed by the teaching staff and they will be decided by draw.
Each work must deliver a broad summary, with the key figures (maximum 10 pages, including figures), which must be delivered in a .pdf file, in the space provided on the Virtual Campus, as well as the slides of the oral presentation that each group must perform during a time not exceeding 15'. Summaries and presentations should be studied by students as they can lead to exam questions.
2b) Group and individual tutorials
They are aimed at supporting the previous training activities and will be carried out in theory or practice hours, with prior announcement by the teacher and acceptance of the date by the students. Additionally, individualized tutoring has been provided in the teacher's office according to the schedule and order that will be indicated on the first day of class.
3. Autonomous activities
This section includes the study, the preparation of the papers and the study of the bibliography of recommended articles.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
The assessment will be carried out on a continuous basis, and will be based on a minimum of 2 written partial tests, which constitute 70% of the final grade.
The original synthesis work on a concrete basin type will be also evaluated (accounting 15% of the final mark); the dossier with the practical exercises will also be evaluated and should contain the overall exercises (accounting 15% of the final mark). All deliveries must be made in the corresponding available space in the Moodle and strictly following instructions (index where appropriate, maximum number of Mb of the document, appointment of the documents, etc.).
In the partial written tests, the data will be determined by the teacher in agreement with the students. The questions may include practical aspects although what is mainly evaluated is the achievement of the theoretical aspects, and in the cases of include practical questions, the degree for solution of problems.
In the work on a specific type of basin, the scientific content, the ordered workflow, the writing and presentation will be evalued, as well as the correct treatment of stratigraphic and sedimentological data from bibliographic sources to produce new synthesis data and documents. A summary of the work, of a maximum of 5 pages including figures, will be deposited in the corresponding Moodle's space for delivery, as well as the ppt of the oral presentation that each student will have to do according to a maximum time no higher than 10 '. This activity assigns a value of 15% of the final mark.
The dossier of practical exercises will also be evaluated with all the finished practices, ordered chronologically, and this dossier must clearly reflect personal work. The verification of a copy of an exercise implies to fail the subject. This activity assigns you a value of 15% of the final mark.
Its is necessary to remark that the subject contemplates a degree of obligatory attendance to both theory and practical exercises classes.
The directed activities mean a substantial part of the learning activities of the subject. In order for a student to be evaluated by continuous assessment, he must attend [1] at least 70% of the theoretical sessions, and each day of presentations of works (both of the same student and of the different groups of students) and [2] 80% of the practical sessions with delivery of the dossier within the fixed time period and before deadline (day and hour determined by agreement between the teacher and the students).
Recovery tests
Students not passing the subject through continuous assessment may have a final oportunity. The subject of examination in the final exam is the full content of the course. In case of not having submitted the final dossier of the practical exercises and/or the work on a type of basin, the student who wants a recovery exam will have to deliver these works at the time of the final test for recovery. For the final note, the same percentages are maintained than in the case of continuous evaluation (70% for the written test, 15% for work on a determined basin and 15% corresponding to the practice dossier). The note of this last test fully replaces the note previously obtained by continuous evaluation.
