Course description and aims

This course focuses on geochemical application of radiogenic isotopes by following the textbook "Geochemistry" by W. White. The basic knowledge about radiogenic isotopes will be given in the first seven classes. In the second half of the course, students will make presentations regarding the topics below;
1) Classical but essential tracers (Sr, Nd, Pb)
2) K-Ar and Ar-Ar dating
3) Rare gas geochemistry
4) Non traditional isotopes

Student learning outcomes

At the end of this course, students will be able to understand:
1) principles for radioactive decay and the origin of isotopes
2) geochemical applications of radiogenic isotopes
3) dating of earth's materials
4) geochemical evolution of mantle and crust

Keywords

Radiogenic isotopes, Mantle, Crust, Chemical evolution, Chronology

Competencies that will be developed

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

Class flow

Before coming to class, students should read the course schedule and prepare for the topics with handouts and references.

Reference books, course materials, etc.

Handouts will be provided during the class

Assessment criteria and methods

Students will be assessed on their understanding of the geochemical application of radiogenic isotopes.
Students' course scores are based on discussion during the class (30%) and group presentation (70%).
