Vida terrestre - Proteger, recuperar e promover o uso sustentável dos ecossistemas terrestres, gerir de forma sustentável as florestas, combater a desertificação, deter e reverter a degradação da Terra e deter a perda da biodiversidade.

Learning Goals

This course aims at an in-depth and integrating understanding of different metallogenic processes through the analysis and interpretation of the geological, thermodynamic and physico-chemical conditions prevailing during the genesis of mineral deposits through the creation of a metallogenic model.
The practical component seeks with a learn by doing approach where students build a metallogenic model of a case study. The case studies will be essentially Iberian, nevertheless, the possibility of working with world-class deposits will not be neglected.

Theoretical
1- Metallogenic models: Basic concepts, utility and examples of use
2- Types of metallogenic models:
3- Descriptive models and the classification of mineral deposits:
3.1- Models related to igneous and hydrothermal processes;
3.2- Models related to metamorphic processes;
3.3- Models related to sedimentary processes;
3.4- Other mineralizing processes
4- Application of grade-tonnage models to quantify deposits
5- Application of probability of occurrence models to geological-mining prospecting
6- Genetic models and their applications
7- Critical analysis and source of error of the metallogenic models
8- Geodynamic framework of the metallogenic models
Practice
1- Creation of a metallogenic model from a case study
1.1- Collection of relevant information and creation of database
1.2- Implementation of a descriptive and tonnage models
1.3- Error evaluation in the model created
2-Technical visit to Portuguese case studies

Teaching Methods

The teaching will involve theoretical classes, practical classes and field work. In the former are provided the principles and methods that will allow to understand the metallogenic models and their methods of study. In the practical classes and field work will be provided the tools that will allow through a case study to learn to apply these methods. Whenever possible students should be included in projects in operation and the teaching will be done in the context of research in development in the Department of Geosciences.
The evaluation will have a continuous evaluation component (15%; student involvement and availability, application of acquired knowledge, etc.), complemented by a theoretical examination (3%), assessment of the written report (35%) on the case study and its oral presentation (15%).
