Course description and aims

Geochemistry is a research field which tries to discover fundamental principles and laws that control the distribution of elements, isotopes, and chemical species in the solar system and the earth. In addition to fundamental researches, geochemistry is intimately related to applications such as space exploration and resource survey. Consequently, geochemistry has been developed significantly in the last 100 years of its history, becoming extremely important in earth and planetary sciences. This course consists of basic and application classes regarding geochemistry and cosmochemistry, specifically focusing on the origin and evolution of the solar system. The fundamentals for elements and isotopes will be given in the first five classes, followed by the classes introducing the applications utilizing such tracers for elucidating the origin and evolution of the solar system.

Student learning outcomes

At the end of this course, students will be able to understand:
1) the origin of elements and the solar system
2) the timescale for the evolution of early solar system and early earth
3) chemical and isotopic distribution in the solar system and within the planets

Keywords

Elements, Isotopes, Meteorites, Early solar system, Early earth, Chronology

Competencies that will be developed

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