The course aims to provide students with a fundamental understanding of geological mineralogy, an introduction to the exploitation of mineral resources and the associated issues of environmental sustainability, and an overview of the use of geological materials in science, art, and technology. Upon successful completion of the course, students will be able to identify and interpret rocks and minerals within their geological and territorial context, understand their significance in terms of the Earth's genesis and geological evolution, and evaluate their use by society in accordance with the principles of environmental sustainability

To be admitted to the exam attendance of at least 50% of both lectures and practice sessions is mandatory. Working students are exempt from the attendance requirement for lectures, but they must still attend at least 50% of the laboratory sessions.Type of evaluation
The two-hour exam will include both open-ended and multiple-choice questions. The final grade will be based on the number of correct answers to the multiple-choice questions, as well as the quality and relevance of the responses to the open-ended questions. teacher profile teaching materials
