Environmental Mineralogy (GEOL 40095/50095/60096-006) – Fall 2012 Syllabus Instructor: David Singer Meeting Times and Place: Tuesday, Thursday; 12:30 - 01:45 pm; McGilvrey 234 Website: https://sites.google.com/a/kent.edu/dsinger/ Drop box address: https://dropbox.kent.edu/login.cfm?id=1843 Course Description: Based on the foundation of mineralogy and (bio)geochemistry, this class will explore reactions between minerals and aqueous solutions, including growth and dissolution, surface complexation, and redox reactions. We will focus on the role of these reactions in chemical weathering, contaminant mobility, microbe-mineral interactions, and an understanding of mineral-water interface processes and mechanisms at the molecular level. Common analytical methods used in mineral-water interface studies will be introduced throughout the course. A series of cases studies will be placed in a historical and geological context. The underlying mineralogy and (bio)geochemistry of each case study will be emphasized. An emphasis will also be placed on the potential role of remediation and the societal impacts of each contaminant. Learning Outcomes Understand the processes that control mineral reactivity and stability under environmentally-relevant conditions. Understand the earth processes which control the abundance and distribution of minerals at the earth’s surface under a range of spatial and temporal scales. Become familiar with common and cutting-edge analytical methods used in mineralogy and (bio)geochemistry. Effectively read and critically review scientific literature. In-Class Activities: Course grades will be determined based on one exam, homework assignments and two presentation and paper projects. Exam (30%): After about 1/3 of the way through the course, students will be tested on the fundamental, background material covered in the first 10 lectures. The exam is intended to gauge the progress made, and make sure everyone is on the same page moving forward to case studies. This will be a take-home exam, but students will be given a lecture off to work on it. Project 1 (30%): Students will select a mineral or class of minerals relevant to surface and near-surface settings. Each student will prepare a 15 minute presentation and a 6-10 page paper reviewing the structure, occurrence, formation, chemical properties, and economic and/or environmental relevance of this mineral. Project 2 (40%): Students will select a topic of interest not covered in detail in the class in consultation with the instructor. Each student will prepare a 20 minute presentation and a 15-20 page paper reviewing that topic. Out-of-Class Activities: Students will participate in a visit and demonstration at the Liquid Crystal Institute on mineral surface characterization techniques. Reading Material and Resources: There is no assigned textbook. Handouts and papers will be provided throughout the semester as reading assignments. To save paper, materials available over the internet will be linked to on the course website instead of being handed out in print.
