Number: 23432 Prerequisites: At least an introductory Geology class Laboratory: The required lab sections of this class are scheduled for M 9.30-12.20 W 11.30-2.20 or 2.30-5.30 Monday 3.00-5.50 will be canceled UTEP requires ~10 per lab, so one of the Wed labs will be canceled TA: Valerie Finlayson, Lauren Storm Field: see lab schedule Bring boots, notebook, handlens, hat, etc Course Topics Topics for the course: -Placing rocks in tectonic/planetary context -Making igneous rocks -Magmas -Stable minerals and assemblages -Chemical petrology (geochemistry) -Making metamorphic rocks -Metamorphic textures -Metamorphic reactions 2
Course textbook Title: Principles of Igneous and Metamorphic Petrology Authors: John Winter Publisher: 2010 edition (2001). ISBN 0321592573 How will we use it? Backup reference to lecture material (assigned reading) Preparation for midterm NOTE: there may also be some scientific journal articles as part of the reading material Course Website Website address: http://www.geo.utep.edu/pub/jasper/ petrology What will be on it: Course syllabus & information Lecture schedule & assigned reading Lecture blank notes Lab report due dates Movies/animations shown in class Class updates/announcements 3
Blank Notes Available at course website (by noon at the latest) Contain slide images only (no text) Sometimes lengthy text notes will be provided = notes provided Attendance & Etiquette No official attendance taken, but.

Grading Policy Course components: Question of the Day Mid-Term Exam 1 Mid-Term Exam 2 Final Exam 7% 20% 20% 20% 33% Laboratory Letter grade breakdown: A = 90%+; B = 80 89%; C = 70 79%; D = 60 69%; F = < 60 Question of the day We will set up a schedule where one student will pose a question to the class about one of the main topics from the last lecture. Rest of the class will turn in their answer, after which the student asking the question will explain the answer Correct answer = 1 point; Incorrect answer = 0 points Questions will count 7% toward your total grade EXTRA CREDIT: By answering all Qs correctly over the entire semester, you can earn up to 3% extra credit 5
Homework Regular homework will NOT be assigned, HOWEVER: Reports on the labs will have to be turned in for a grade NO late reports will be accepted Format: Type it or write neatly, and use proper grammar & punc. Working together: Encouraged, however you must turn in your own assignment, using your own words. Any student who fails to follow this rule will receive zero credit for the question, and if the offense is severe, for the assignment. Free lab pass: Your lowest lab score will be dropped assuming you turn them all in. If you miss a lab for any reason, that counts as a 0 and that will be the lab that is dropped. Two midterm exams Final Exams Make-up/early midterm: Will not be given except for an excused illness (doctor s note required) or family emergency Anyone with conflicts due to extracurricular activities must provide at least 2 weeks notice with appropriate signed paperwork Make-up exam will be substantially more difficult than the exam given to the rest of the class.
