Presentation
In this training, students have the opportunity to understand the genesis and occurrence of igneous and metamorphic rocks, according to the petrogenetic cycle and from a geodynamic perspective.
Sustainable Development Goals
Learning Goals
Understand the genesis and occurrence of igneous and metamorphic rocks, according to the petrogenetic cycle and based on a geodynamic perspective resulting from the interaction between the rock cycle and the tectonic cycle.
Systematize and use the classifications of igneous and metamorphic rocks according to their structural, chemical and mineralogical features.
Petrographic analysis and identification of igneous and metamorphic rocks in hand samples and under the petrographic microscope, based on textural features, mineralogical composition and mineralogical transformations and/or readjustments.
Relating the different types of igneous and metamorphic rocks, with specific petrogenetic processes and setting them according to a global tectonic approach.

Teaching Methods
1 - Theoretical classes with presentation and conceptualization of topics, encouraging the active and comprehensive participation of students.
2 Practical laboratory classes, with theoretical thematic introduction followed by petrographic analysis of igneous and metamorphic rocks at meso (hand sample) and microscopic scale (thin section), allows the training in the rock classification based on the observed mineral and textural features.
3 - Tutorial orientation allowing the monitoring of students through the Moodle platform (e-learning).
4 - Continuous evaluation through the semester by the assessment of 2 theoretical-practical tests or by final evaluation by theoretical and practical exams (60% theoretical exam + 40% practical exam).
