Course description and aims

For decoding the evolution of solid Earth over its 4.55 billion year history, it is quite important to learn how chemical differetiation proceed through igneous processes in the variety of tectonic settings on modern Earth. In this course, the basic knowledge about igneous processes, as the fundamental role on creating variety of igneous rocks, will be given with their geological occurrences, and the spatiotemporal variations of chemical differentiaion in solid Earth will be able to understand.

Student learning outcomes

Goals of this course are:
1) to understand basics of igneous petrology and solid Earth geochemistry
2) to understand the relationship between rock formation and chemial evolution of the solid Earth

Keywords

Igneous petrology, Solid Earth geochemistry, Magma, Crust, Mantle, Earth's evolution

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

First half: Before coming to class, students should read the course schedule and prepare for the topics with handouts and references. The second half: students will make presentations regarding the topics given in the first half of classes.

Course schedule/Required learning

  Course schedule Required learning

Class 14 Presentation 6 (komatiite magma) Understanding of the current debate on the formation of komatiite magma
Class 15 Presentation 7 (tectosphere) Understanding of the current debate on the formation of tectosphere (cratonic mantle)

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Textbook(s)

Paul C. Hess "Origins of Igneous Rocks" Harvard University Press

Reference books, course materials, etc.

Handouts will be provided during the class

Assessment criteria and methods

Students will be assessed on their understanding of (1) the role of igneous processes for creating variability of rocks, and (2) what extent of solid Earth's history was revealed. Students' course scores are based on discussion during the class (30%) and group presentation (70%).
