Learning Goals

In this curricular unit the student should use the knowledge of the processes involved in the genesis of classical orogens, to make the analysis and interpretation of deformed regions.

In order to reach this objective, it is fundamental that it develops the capacity of integration, in space and time, of the processes of sedimentation, deformation, magmatism and metamorphism, associated with the genesis of orogenic belts. The correct interpretation of the geodynamic evolution of a deformed region from the pre-orogenic period to the end of the tectonic cycle is the main challenge for students who attend this curricular unit.

Contents

THEORETICAL COMPONENT
1. Introduction
2 - Subduction zones, island arcs and active continental margins.
3 - Terranes
4 - General structure of orogenic belts.
5 – Young orogens
5.1 - Ocean-continent convergence, the example of the Andes.
5.2 - Continental collision, the example of the Himalayas.
5.3 – Arc-continent collision, the example of Timor.
6 – The variscan orogens based on Geology of the Iberian Peninsula.
7 - Structure and geodynamic evolution of the SW region of Iberia Peninsula - introduction to the field classes

FIELD COMPONENT
Geotraverse between the Ossa-Morena/Central-Iberian Zone boundary and the SW region of the South Portuguese Zone (4 days).

LABORATORY PRACTICE COMPONENT
Analysis and interpretation of selected geological maps, from the Iberian Peninsula and several other regions of the world.

Teaching Methods

The teaching is based in theoretical classes interspersed with practical classes where concrete situations from geological maps are analyzed.

In practical classes particular attention is paid to the Peninsular variscan basement, but other real cases of the Alpine, Andean and Himalayan chains are also analyzed.

At the end of the semester, during the 4 days of field classes, students are encouraged to plan methodologies to approach the problems that are placed in them, in order to apply the knowledge previously acquired.

The assessment is based on a field trip report (40%), a field exam (20%) and a resolution of an exercise related to the structural interpretation of a map (40%).
