Learning objectives

At the end of this part of the course, the students will be able to apply their knowledge and skills to understanding so as to
identify, by examination of hand samples and thin sections, the three principal groups of rocks (igneous, metamorphic, sedimentary) outcropping on the Earth’s surface.

Course unit content

Laboratory activity.
1) Basic methods used to describe and identify hand specimens of the Earth’s crust and mantle rocks (i.e., igneous, metamorphic and sedimentary rocks).
2) Optical mineralogy methods used to identify the common rock-forming minerals in thin section, by use of polarizing optical microscope.
3) Classification of the magmatic, metamorphic and sedimentary rocks according to their mineral content and texture, following the schemes proposed by the International Union of Geological Sciences.

Teaching methods

The 12 credits of this course amount to a total of 120 hours, distributed as follows: 80 hours of laboratory-based exercises and 40 hours of lectures. In the laboratory part, the student perform exercises on the identification of hand specimens of rocks and a strong training on the use of the microscope; formative evaluation will be done informally with discussions during each lesson, in order to check how much students have been understood. Written evaluations will be carried out periodically, in order to monitor the achievement of the training objectives. The teacher uses PowerPoint files that display the sequence of course topics.

Assessment methods and criteria

The exam is made of a written part and an oral part.
In the written part, the student describes the mineral assemblage and the texture observed in 3 thin sections (1 for a intrusive igneous rock; 1 for an effusive igneous rock; 1 for a metamorphic rock), using microscope techniques; then, by using this petrographic information, the student classifies the rock. The written part will also be carried out during the course. The minimum score to pass the written part is 18/30.
After the correction of the written part, the student takes the oral part of the exam.
