1.2. Context and importance of this course in the degree

This course is part of a group of subjects in the Degree in Geology that constitute the basin background for geologists to understand the Earth as a whole and to apply geophysical techniques to geological problems.

1.3. Recommendations to take this course

This module requires comprehension of tectonic structures and Geology and basic Physics and Mathematics knowledge to understand the fundamentals of Geophysics. Abilities to work with contour maps, cross-sections and a minimum background of informatics are not compulsory but can help.

2.1. Competences

After completing the course, the student will be competent in the following skills:

  • Ability to transfer geophysical information to geological features.

  • Capacity to understand the Earth as a whole and the implications that its structure has for the different disciplines in Earth Sciences.

  • Skills to work with contour maps of potential fields.

  • Ability to solve elementary problems in geophysics.

  • Capacity to interpret seismic reflection profiles in terms of geological cross-sections.

  • Skills to obtain information from earthquake parameters.

  • Capacity to solve questions of plate kinematics by means of vectorial calculations, paleomagnetism and magnetic anomalies of the ocean floor.

  • Ability to understand mechanisms of heat transfer within the Earth and their implication in plate tectonics.

2.2. Learning goals

During this module the student will develop:

  • Knowledge of the main methods in geological surveying and their use for the understanding of the internal structure of the Earth and for solving geological problems.

  • Ability to work with gravimetric and magnetic anomaly maps and interpret them according to the geological background.

  • Ability to derive and solve problems related to seismic surveying (refraction and reflection).

  • Ability to analyse plate kinematics and to interpret associated geological structures in plate boundaries.

  • Understanding of the main processing methods in geophysics.

  • Basic understanding of rheological models of the oceanic and continental lithospheres, and mechanisms of deformation at different levels within the crust.

  • Intellectual skills to integrate her/his geological knowledge within the frame of Global Tectonics.

2.3. Importance of learning goals

The understanding of the structure of the Earth as a whole, the meaning of geophysical data, the kinematics of tectonic plates, and the application of geophysical methods to Geology is a basic part of the background in Earth Sciences for all geologists, whatever their field of specialization.

3.1. Assessment tasks (description of tasks, marking system and assessment criteria)

The student will prove that she/he has achieved the expected learning results by means of the following assessment tasks:

Continuous assessment

1. Resolution of 3 tests during the semester, using skills and basic knowledge acquired in the lectures and lab sessions. Minimum score 5 out of 10. Slightly lower scores can be balanced between different assessments.

Categorising performance levels:

  • Excellent performance (9-10 points): knowledge and problem resolution based on the taught programme

  • Typical performance (7-8 points)

  • Threshold performance (5-6 points)

  • Compensable (4-4.9 points)

  • Failure (0-4 points)

Final assessment

1. In case of failure of one or more of the continuous assessment tests (minimum score 5 out of 10), the final assessment is a second-chance examination, also for students that cannot attend the normal development of the module.

4.1. Methodological overview

The methodology followed in this course is oriented towards the achievement of the learning objectives. A wide range of teaching and learning tasks are implemented, such as lectures, laboratory sessions, seminars, tutorials and assessment tasks.

4.2. Learning tasks

This 6 ECTS course is organized as follows:

  • Lectures (24 hours). Two weekly hours. The students will have class notes given by the professor as the basis for their learning, that must be completed with important remarks during the lectures and the laboratory sessions. Study of basic handbooks is strongly recommended.
  • Laboratory sessions and seminars (36 hours). Two weekly hours.
  • Tutorials. The tutorials will be considered as another academic activity where the students will be free to ask about any topic concerning the course.
  • Assessment tasks (8 hours). It includes assessments and comments about them, which serves as a powerful learning tool (3 assessments in continuous evaluation modality). There are also two final resit exams. Exams include laboratory and theoretical questions, typically 13.
