3 credits - Fall 2014 - Tuesdays 3:30-4:30 and Wednesdays 11:30-12:30 in FDA 348
We will meet 1-2 times per week. The first meeting will be a discussion session focused around 1-2 journal articles, with discussions run by students. The second meeting will be held for student presentations on practical applications and methods, and presentations of project results (mostly in the 2nd half of the semester).
The course includes 1 field trip (September 10-13) to visit the Norumbega Shear Zone. We will visit a number of exposures representing a range of depths of deformation, and will map a fracture/fault/pseudotachylyte network in a newly discovered exposure to generate a data set for use in the class. We will be collaborating with Mark Swanson and Steve Pollock and their students from University of Southern Maine. If the work is successful, the class will have the opportunity to co-author a publication.
Pre-req: structural geology. Background in tectonics, metamorphic geology, and geophysics would be useful.
|5%||1 page + figures for field trip handout|
|30%||Reading Seminar (meets weekly)
Each week, one student will present 10-15 min overview of reading material, with slides or examples, and lead the discussion. Students will lead discussion twice during the semester.
|20% Leading discussion|
|25%||Give a lesson:
Teach the other students about some research method of your choice. This could be a technique you use in your own research, or something you have never done but would like to learn. You can demonstrate the method, teach a lesson, or give a lecture about it illustrated with examples. You will have 30 minutes for this lesson.
|40%||Individual Research Project could involve microstructural studies, analytical studies, or modeling. Data and samples collected on the class field trip may be used for the project.||25% Paper Instructions here|
|5% Peer reviews written for other students|
|15% Presentation (20 minutes)|
McGill University values academic integrity. Therefore, all students must understand the meaning and consequences of cheating, plagiarism and other academic offences under the Code of Student Conduct and Disciplinary Procedures (see www.mcgill.ca/students/srr/honest/ for more information).
