Course description: This course is given to graduate students of the Dept. of Geosciences, whose research issues are related to development of geochemical analytical techniques and their application to earth sciences. The topics include (1) sampling methods for different geochemical samples; (2) theoretical and practical aspects of chemical procedures and mass spectrometries; (3) instrumental techniques for high precision determination of trace metals and isotopes; (4) development of frontier analytical methods; and (5) application of analytical techniques to researches of global change and environmental variation. Weekly paper reading, discussion and presentation will play essential roles in class. After taking this class, students will be capable of performing their own thesis research and preparing scientific articles.
Text materials: papers, class handouts.
Grading: Report and presentation, 70%; Final, 30%.
