Teaching language

Portuguese

Objectives

The CU of “Geological resources” is fundamental for the students of Geology and Sciences because by the first time basic concepts on Economic Geology and Sustainability are given.
It is demonstrated that a deposit is only possible after a good chaining of different geological processes.
We describe some types of ore deposits given also particular emphasis to the Portuguese deposits.

Learning outcomes and competences

Learning Outcomes (LO)

Upon completion of this unit, students will be able to:

1. comprehend the alteration and mineralisation characteristics of the more economically important ore deposit types;
2. identify and recognise the geological implications of ore textures, alteration and mineralization styles through practical and field excursion experience;
3. understand exploration methods and their complexities; and
4. synthesize observational and other data and produce a geologic interpretation.

 

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

It is desirable that students have attended the UC Geodynamics (G111), Petrology (G232 and G234) and Structural Geology (G213).

Teaching methods and learning activities

Teorethical classes
The geological setting, characteristics, physicochemical conditions of formation, economics and exploration of deposits related to magmatic crystallisation, late magmatic igneous hydrothermal activity, subvolcanic and volcanic activity, submarine exhalations, diagenesis, surficial processes and metamorphism.

Practical Classes for metallographic studies.
Practical work is on the identificaiton of mineralogy, petrology and exploration parameters of mineral deposits and their enclosing rocks, petrographic analysis of hand samples  and thin sections.
