Objectif

This course presents a synthesis of the petrologic and tectonic processes that occur during plate tectonics, and it will cover both the Phanerozoic and the Precambrian. The course is sub-divided into five parts.

Contenu

1) Evolution of the early Earth: The very early stages of development of planet Earth were characterized by unique geological conditions, which differed from those during the Phanerozoic. These differences had profound consequences for the thermal regime of the Earth, the atmosphere, the nature of the Earth's crust, and many other aspects of evolution of the Earth. We will review several proposed mechanisms for the formation of the Earth (accretion), formation of the proto-crust, the development of the atmosphere and hydrosphere, the initiation of plate tectonics, and also other events such as episodic global glaciation (snowball Earth). The afternoons will be used for exercises and personal reading.

First seminar (1 day): Each student presents a seminar about a scientific paper.

2) Mantle: Structure, composition and evolution of the mantle.

3) Subduction: Mornings will be devoted to aspects of metamorphism, magmatism, geophysics, thermo-mechanical processes and experimental petrology. Students will carry out individual work during the afternoon periods.

Second seminar talk (1 day): Each student presents a seminar about a scientific paper.

4) Rifting and oceanic crust: We will study the processes linked to the movements of continents, the development of passive margins and the structure and composition of the oceanic crust. Different tectonic models for rifting and lithospheric extension (examples from geology and quantitative models) will be discussed and explained.

5) Collision: This chapter will cover crustal magmatism, transport of magma and its emplacement into the middle and upper crust, rheology of the lithosphere, and the formation of structures that typically form during collision. We will discuss the tectonic processes that occur during collision, and these will be applied to the Alpine Orogeny.

Presentation of the Main Seminar: This seminar will be presented by each student. Students can who can select a topic from a list provided by the responsible teachers. The seminar work will include a literature search, an oral presentation and a written report.
