Short description: Topics in Geochemical Kinetics span a broad range of geochemical subdisciplines including low-temperature aqueous, organic, isotope and igneous geochemistry. Consequently, the course is not limited to a narrow range of geochemistry students. Geochemical Kinetics covers both experimental, numerical and analytical approaches to problems. Discussion of these various approaches in class allows assignments to be given that cover data analysis, molecular simulation and theoretical calculations. Assignments in GEOSC 560 consist of quantitative data analysis and modeling. Most work will require learning elementary programming skills to analyze data or make theoretical predictions. A term paper and oral presentation are required on a topic (selected by the student) related to geochemical kinetics. Quantitative data analysis or modeling should be included as part of methodology and results. Class discussions of papers on special topics are an integral part of the course.
