Objectives

This course aims to consolidate the fundamental concepts of Economic Geology and Sustainability in mineral resources. Once a concentration is only possible thanks to the happy chaining several geological processes is an approach the main types of ore deposits.

Learning outcomes and competences

It is intended that at the end of the UC Students have obtained the ability to view the metallogenic processes a holistic point of view based on recent conceptualizations around the notion of tectonic environment.

Teaching methods and learning activities

All lessons are theoretical-practical, being verbal exposition of the contents to the students being always accompanied by audiovisual media. All lessons take place in the Museum of Mineral Deposits, so the samples of ores and minerals there are a resource used by students for the appropriation of the subjects that are being taught.

Eligibility for exams

All classes are theoretical-practical.
Obtaining frequency to the discipline implies:
1 - According to the rules of the FEUP -75% attendance in classes
2 - Group or individual work

Calculation formula of final grade

Examination will be the average components distributed assessment.

Distributed Component (CD): 25%

• CD1 - Monographs:  20%
• CD2 - Attendance - 5%

Exam - 75%

NF = 0.25* CD + 0.75 *Exam

 Students whose note NF is less than 10, will undergo the 2nd examination.
