Prerequisites

Since it is a subject that involves the observation of different types of rocks and structures in the field and its analysis in a broad geodynamic context, it is necessary that the student be able to:

  • recognize the different types of sedimentary rocks and their significance
  • recognize metamorphic and plutonic rocks and relate them to structural and petrogenetic processes,
  • recognize and interpret geological structures and perform data collection
  • interpret geological maps.

Therefore, it is recommended that the student has passed the second year subjects (or third year of double degree)  and is taking (or has taken) the rest of the compulsory third year subjects (or fourth year double degrre)

Objectives

The goal is to study on the field the geology of the Variscan Iberian Massif observing the different lithologies and structural styles, and deducing the tectonic and petrological processes that took place during the orogeny. To this end, an E-W cross-section will be made along the NW of the Iberian Peninsula, from the external to the internal parts of the orogen. This geotraverse is one of the most complete examples of an ancient orogen and constitutes a model of international interest.

Theory:

  • The Variscan Massif of the Iberian Peninsula, its zonation and structure (2 h).
  • Variscan metamorphism and magmatism. Evolution of metamorphism. Age and characteristics of the magmatism (1 h). Evolution of the Iberian Variscan Orogen (1 h).


Seminars:

  • The Stratigraphy and Palaeontology of the region (4 h-1.5 h evaluation of the seminar)
  • Geological resources of economic interest (4 h-1.5 h evaluation of the seminar)


Fieldwork:

6 field work days doing a transect of the Varian Massif of the NW of the Iberian Peninsula from the external to the internal zones. Before the field trip, the student will take a previous exam on the theoretical classes taught. During the fieldwork, emphasis will be placed on the elaboration of a personal field notebook in which the student will collect information on the outcrops or structures that are visited. The student must be interested in keeping the notebook up to date because its presentation (or that of exercises to be carried out not included in the field notebook) may be required at any stage during the fieldtrip in order to grade it. Exams (3) will be carried out to evaluate the work done during the field trip. On the last day of the field trip, an exam of the entire content of the fieldwork will be done.Teachers will spend approximately 15 minutes afterthe field trip to allow their students to answer the surveys for the evaluation of teaching performance and evaluation of the subject.

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

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Seminar on Stratigraphy and Paleontology of the studied region 15% 1.5 0.06 CM28, KM38, SM33, SM35

Pre-departure test on the evolution of the Northern branch of the Iberian Variscan Massif 10% 4 0.16 KM37, KM38, SM33
Final examination of the fieldwork 30% 4 0.16 CM27, CM28, KM37, KM38, KM39, SM33, SM34, SM35

CONTINOUS ASSESMENT:


Mandatory presentiality:

In order for a student to be evaluated, he / she must meet the following minimum assistance requirements :

  • To attend every day on the fieldtrip
  • To attend at least, 80% of the theoretical sessions
  • To attend at least, 80% of the seminars.


Assessment system for the acquisition of skills and qualification system:

  • Evaluation of the Seminar on Geological Resources of Economic Interest 15%
  • Evaluation of the Seminar on Stratigraphy and Paleontology of the region 15%
  • Previous to the fieldtrip exam: 10%
  • Evaluation of field work: Evaluation of daily work in the field (3 field exams + supervision of the field notebook and/or exercices) 30%
  • Final field exam 30%


All exams are mandatory. The non-assistance to some prevents to pass the subject. When the score obtained on some of the Seminars, on the Previous to the fieldtrip exam or on the final field exam is less than 3,5 points, a retake exam will be compulsory. To achieve a grade lower than 3.5 points in the retake exam of any of the items prevents to approve the subject.


If a student has carried out evaluation activities exceeding 45% of the total of the subject content, she / he will be graded as failed and he /she will be not allowed to have the qualification of unassessable.


SINGLE ASSESSMENT:

This subject does not incorporate single assessment


Other considerations:

In the event of a student committing any irregularity that may lead to a significant variation inthe grade awarded to an assessment activity, the student will be given a zero for this activity, regardless of any disciplinary process that may take place. In the event of several irregularities in assessment activities of the same subject, the student will be given a zero as the final grade for this subject. Those assessment acts where irregularities have been detected (copy, bad use of AI, etc) are not recoverable.

This subject allows the use of AI technologies exclusively for support tasks such as: bibliographic or content-based searches, text correction or translations, or at teachers criteria. The student must clearly (i) identify which parts have been generated using AI technology; (ii) specify the tools used; and (iii) include a critical reflection on how these have influenced the process and final outcome of the activity. Lack of transparency regarding the use of AI in the assessed activity will be considered academic dishonesty; the corresponding grade may be lowered, or the work may even be awarded a zero. In cases of greater infringement, more serious action may be taken.
