To have passed the subjects "Fundamentals of Geology" and "Work of Field of Regional Geology" of the first course of the Degree of Geology and of first and second year respectively of the double degree in Environmental Sciences and Geology.

To recognize, identify and interpret ductile deformation structures and their association in different tectonic contexts. This will be done both from a theoretical (genesis of structures) and analytical point of view (real structures). Emphasis will be placed on the student's acquisition of the ability to use the appropriate terminology of structural geology and the acquisition of skills to represent the structural characteristics throughout different methods of graphic representation (maps, cross-sections, detail schemes, stereographic projection and other specific techniques).

- Display understanding of the size of the space and time dimensions of Earth processes, on different scales.
- Draw up and interpret geological maps and other means of depicting geological information (columns, correlation frames, geological cross-sections, etc.)
- Learn and apply the knowledge acquired, and use it to solve problems.
- Process, interpret and present field data using qualitative and quantitative techniques, and suitable computer programmes.
- Recognise, depict and reconstruct tectonic structures and the processes that generate them and relate types of rocks and structures to geodynamic environments.
- Suitably transmit information, verbally, graphically and in writing, using modern information and communication technologies.
- Synthesise and analyse information critically.
- Use concepts from physics when solving problems in geology.
- Work independently.

- Discern the deformation processes on different scales.
- Draw up geological maps of structurally complex regions and geological cross-sections.
- Draw up structural subsoil models, based on geological cross-sections and three-dimensional block diagrams.
- Formulate and verify hypotheses of a structural and tectonic nature.
- Interpret the mechanical behaviour of geological materials in accordance with physical parameters.
- Learn and apply the knowledge acquired, and use it to solve problems.
- Process, interpret and present structural data.
- Recognise and depict the principal tectonic structures.
- Relate deformation structures to tectonic stress.
- Relate the principal tectonic structures to structural and petrogenetic processes.
- Suitably transmit information, verbally, graphically and in writing, using modern information and communication technologies.
- Synthesise and analyse information critically.
- Work independently.

FIELD PRACTICES

Tectonic structures in Cap de Creus (2 field trip days)

-First day: Cadaqués-Guillola-Puig Culip. Recognition and elaboration of cross-sections and structural schemes of zones with folds and associated foliations.

- Second day: Puig Culip - Culleró. Recognition and detail mapping of areas with folds and associated foliations in domains of intense metamorphism and magmatic activity. Relationships tectonics/metamorphism/magmatism. Shear zones.

A combined approach between the theoretical approach (block 1) and the most descriptive (block 2) with a continuous feedback between the reference to the undeformed state (original geological object) and the reference to the deformed state (real structure). This approach applies to the whole course, so that the concepts explained in theory, practices and in the field are interrelated continuously.

**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.

Title | Hours | ECTS | Learning Outcomes |
---|---|---|---|

Type: Directed | |||

Classroom exercises | 12 | 0.48 | 2, 7 |

Field practices (field excursions) | 14 | 0.56 | 1, 2, 5, 7, 8, 10, 11, 13 |

Lectures | 25 | 1 | 1, 5, 10 |

Type: Autonomous | |||

To learn the theoretical and practical concepts complemented with bibliographic information, complementary practical works | 84 | 3.36 | 12, 1, 4, 5, 10, 11, 13 |

The final assessment and qualification will be based on the sum of the evaluations of (1) practice dossier, (2) field work, (3) theoretical-practical test of Block 1 and (4) the examination of Blocks 2 and 3. This gives 4 notes from which the weighted average will be obtained based on the specific weight of each of the parts (proportional to the number of hours spent).

To pass the subject via continuous evaluation, it will be necessary to have a minimum average mark of 5 and have done all the tests, participated in the filed trips and delivered all course works within the established deadlines. To average different parts a minimum mark of 3.5 is required for each part. In no case will the student be able to pass the subject if he has not carried out the field trips or if he has not presented the classroom practices and the dossiers.

Resit: If these requiremenst are not fullfilled, or if the resulting final average is less than 5, a resit test can be done on the date of the final evaluation. In order to be able to attend the resit exam, the student must have been previously evaluated of continuous assessment activities that are equivalent to 2/3 of the final mark. The recoverable activities in this final examination will be the activities (3) and (4). Students approved via continuous evaluation but who wish to improve their mark may choose to do so on the same date as the final assessment.
