The rocks contituting the crusts of all the inner planets so far explored are composed of a relative few of the nearly 3000 mineral species and varieties known to mineralogists. The most common rock-forming minerals are silicates (see Vol. IVA: Mineral Classes: Silicates), but they also include oxides, hydroxides, sulfides, sulfates, carbonates, phosphates, and halides (see Vol. IVA: Mineral Classes: Nonsilicates). The major rock-forming minerals and mineral groups listed in Table 1 are classified after Deer et al., 1966.
This course is a refresher in thin section microscopy with special emphasis on textural interpretation and petrogenetic implications. The focus is on volcanic rocks from oceanic ridges and islands, but the manifestation of deformation and hydrothermal alteration in ocean crustal rocks will also be dealt with.
REQUIREMENTS:
- Basic experience in investigations of thin sections with a polarizing microscope.
- Basic knowledge of petrology and petrography of igneous rocks.
A PARTICIPATION IN THIS COURSE IS NOT RECOMMENDED FOR STUDENTS WHO DO NOT MEET THESE PRECONDITIONS.
After completion of the course the students are able to:
- identify a number of rock-forming minerals
- use petrography to recognize petrogenetic processes
- assess the possibilities and limits of petrographic investigations
The aim of the course is twofold:
1- acquisition of knowledge concerning the main petrogenetic processes
(magmatic and metamorphic) in the different geodynamic
settings.
2- to provide the knowledge for rock identification based on their
structural and textural features and mineral associations (examination of
hand samples and rock thin sections under polarized light microscope).
The course aims to provide the basic knowledge related to rock formation
processes. Methods and procedures for the study of rocks and their
mineralogical constituents will also be illustrated both on the basis of
hand samples and in thin section under petrographic microscope
1. Definition and introduction to the main rock formation processes. The
rock cycle. Geothermal and pressure gradient. Causes and mechanisms
of melting (mantle and crust).
2. Magmatic rocks: chemical and physical characteristics of magmas,
crystallization and evolution of magmas, binary phase diagrams
representative of simplified magmatic systems; magmatic series and
geodynamic environments. Classification and nomenclature of igneous
rocks based on structural and textural characteristics, constituent
minerals and chemical composition. Volcanic processes, types of
eruptions and volcanic products.
3. Metamorphic rocks: definition and environmental conditions of
metamorphism, metamorphic grade, metamorphic facies, fluids and
metamorphism. Minerals and metamorphic structures, nomenclature and
classification of metamorphic rocks.
4. Principles of crystallographic optics and optical mineralogy:
petrographic microscope, orthoscopic and conoscopic observations.
Identification of the main rock-forming minerals (hand sample and thin
section under the microscope). Microstructures of igneous and metamorphic
rocks in thin section. Identification and classification of
the main igneous and metamorphic rocks (hand sample and
thin section under the microscope)
Lectures made using multimedia tools and laboratory.

platform. To download the slides, students need to be registered on-line
to the Course. Please note that the slides are not a substitute for lessons
or of the Textbooks but are considered part of the accompanying
instructional materials. Students should frequently control instructional
materials and other information provided by the Teacher on the Elly web

Written and oral examination. The written examination includes
description and classification of two rock samples in thin section using
petrographic microscope. The oral examination aims to verify the
comprehension of magmatic and metamorphic petrogenetic processes
