Geochemistry uses the tools and principles of chemistry to explain the mechanisms behind geological systems. In the first half of this course, students learn basic methods of mineral separation, density measurement of rock-forming minerals and saline solution, and crystallography analysis. In the second half, students learn chemical analysis of bulk-rock and rock-forming mineral.
The goals are to learn methods for
1) obtaning basic physico-chemical parameters used in geoscience (e.g., rock composition, mineral density) from natural rock sampls,
2) dealing with physico-chemical parameters to understand geological systems.

To enhance effective learning, students are encouraged to spend a certain length of time outside of class on preparation and review (including for assignments), as specified by the Tokyo Institute of Technology Rules on Undergraduate Learning (東京工業大学学修規程) and the Tokyo Institute of Technology Rules on Graduate Learning (東京工業大学大学院学修規程), for each class.
They should do so by referring to textbooks and other course material.
Experiment manual and text are provided before the 1st day of the class.
See Japanese texts listed above.
Check the student's comprehension by
1) lab note filed each after the class,
2) final report after the course of this class.
