91560 - Applied Petrology

Learning outcomes

This course covers the quantitative methods used to infer the evolution of igneous and metamorphic rocks from their mineral assemblages and textures. Students will learn a variety of approaches, from field study to thermodynamic calculations, all of which help to draw conclusions on multi-scale observations of real rocks. Applied petrology includes the understanding of how predictive models for rocks under different pressures, temperatures and fluid compositions are carried out, with a special emphasis on raw materials in general. This unit comprises the study of published work showing the application of petrological methods to ore geology. Knowing basic petrologic concepts and how to perform a microstructural study on thin sections using optical and electronic microscopies are a prerequisite.

Course contents

Definition of the most important petrologic pathways of global volatile recycling as drivers for element mobility/deposition and ore formation. Magma evolutions and key igneous processes. Description, modeling, and interpretation of fluid/melt-rock interaction processes through theoretical and practical applications. Analytical techniques in petrology.

Teaching methods

Lectures, hands-on practices to gain experience on global petrological processes controlling element recycling in the lithosphere. Individual work and reporting on different types of assignments, for example managing geochemical dataset, modeling fluid-rock interactions or magma evolutions. Learning activities may be delivered also in instructed team sessions, to enhance group discussion, or in flipped class to increase student engagement and learning.

Assessment methods

The individual performances are evaluated through the participation in class activities, and through the final written and oral exam. Class participation includes student engagement during lectures and practical work. Each student is expected to deliver a professional-style presentation on the project selected for the final examination, aimed at introducing it to the class and to gather comments and recommendations. The final written exam is a written report dealing with an individual research project. The oral exam is aimed at discussing the individual reports and testing the contents of the course.

The grades in the Italian university system are expressed out of thirty. The passing grade is 18/30. In case of full grade (30/30) the Professor(s) may also decide to award honours (lode).

Here below the breakdown of the final grade

10% Class participation

20% Project presentation

70% Final exam - Written report + oral exam

Students with learning disorders and\or temporary or permanent disabilities: please, contact the office responsible (https://site.unibo.it/studenti-con-disabilita-e-dsa/en/for-students ) as soon as possible so that they can propose acceptable adjustments. The request for adaptation must be submitted in advance (15 days before the exam date) to the lecturer, who will assess the appropriateness of the adjustments, taking into account the teaching objectives.
