Course Objective

The Geochemistry course is essential for all aspects of modern Earth Science. This course for undergraduate students is an introduction to Geochemistry. In the theoretical part of the course, the definition of Geochemistry, atomic structure, isotopes, periodic table, elemental distributions, chemical differentiation of the earth, solution geochemistry, mineral stability diagrams and chemical events that play a role in the formation of mineral deposits due to some external events are aimed to be understood. In the application part of the course, it is aimed to write the ideal and closed formula of a mineral from the result of a chemical analysis of a mineral, to draw and interpret Eh-pH diagrams and to learn the importance of the formation of mineral deposits.

Learning Outcomes of the Course Unit

1   To have knowledge about the structure of atoms, chemical bonds and their importance in geology.
2   Have knowledge about the structure of the earth and geochemical classification of elements.
3   Know how to use major and trace elements to track magmatic processes and make tectonic discrimination.
4   Be able to selecting analysis methods and have knowledge on how to assess the quality of analytical data.
5   Be able to use analysis data to write chemical formula of a mineral.
6   To be able to draw mineral stability diagrams and produce interpretations about the processes that are effective in the formation of mineral deposits.
