GEOL 2020 – Introduction to Petrology Semester/Year: Fall 2007 Lecture Hours: 3 Lab Hours: 2 Credit Hours: 4 Class Time: .1:00-3:25 Days: Tu, Th Room: TM 121 Instructor’s Name: Gerald “Jerry” Nelson Office Phone: 268-22233 Home Phone: 259-7587 Email: [email protected] I very much appreciate email contact, it is quick and efficient, and I usually check my email at least once per day most of the time more often that that. Office Hours: Posted on office door, and by appointment Course Description: Introduces study of igneous and metamorphic rocks in hand sample and thin section. Covers textural and mineralogical features of igneous and metamorphic rocks, chemistry of igneous rocks, phase diagrams controlling mineral crystallization in igneous and metamorphic rocks and tectonic environments in which various igneous and metamorphic rocks are found. Field trip required. Statement of Prerequisites: GEOL 2010 Goal: Introduction to Petrology is fundamental to further study in geology. The main objective of this course is to provide the student with a rigorous background in petrology in preparation for advanced courses and entering the workforce as a professional geologist. Outcomes: Passing Students should: • Be able to identify igneous and metamorphic rocks by testing the physical and optical properties using hand samples and thin sections • Demonstrate their understanding of the chemistry and conditions of formation of common igneous and metamorphic rock and rock assemblages • Understand the relationships between igneous and metamorphic rocks and the earth’s plate tectonic history • Understand the importance of igneous and metamorphic rocks as the source or host of many economically important minerals Methodology: This course will consist of a series of lectures designed to cover the main facets of petrology and the economic importance of igneous and metamorphic rocks. The lectures will explain and expand upon the material in the text, handouts, and reserved references. Since petrology is a lab-intensive topic, students will be expected to do considerable work on their own outside of the regularly scheduled lab meeting time. Students will get an opportunity in lab to examine igneous and metamorphic rocks, using standard methods of hand sample testing and petrographic microscopic analysis. Student evaluation will be as objectively as possible through the use of regularly scheduled exams in both the lab and lecture portions of the class, as well as lab projects. There will be a lot of complicated and important material presented each day, so students are expected to make every effort to attend class meetings, to carefully read all assigned material, and above all, ask questions when confused or unsure. Evaluation Criteria: Lecture is approximately 50% and lab is approximately 50% of your final grade. Lecture grade consists of quizzes, exams and participation. Your lab grade will be based on lab assignments and lab exams. The grade scale is traditional: 90-100% A, 80-89% B, 70-79% C, 60-69% D, <60% F Make-up exams are extremely difficult to arrange in a lab-intensive class. You are expected to make every effort to attend all classes; I may consider make-up exams on a case by case basis, so plan accordingly. If you must miss an exam, you may be allowed to make it up only if you contact me prior to your absence with a believable, significant excuse. Late assignments are accepted with a penalty of half grade for each day overdue. All work must be original. Plagiarism will not be tolerated. Outside help on lab work or assignments will not be allowed without prior approval from the instructor. Required Text, Reading, and Materials: An Introduction to Igneous and Metamorphic Petrology, John D. Winter, plus readings and references given in class Class Policies: Last Date to Change to Audit Status or to Withdraw with a W Grade: Please refer to Casper College catalog and calendar. Student Rights and Responsibilities: Please refer to the Casper College Student Conduct and Judicial Code for information concerning your rights and responsibilities as a Casper College Student. Chain of Command: If you have any problems with this class, you should first contact the instructor in order to solve the problem. If you are not satisfied with the solution offered by the instructor, you should then take your problem through the appropriate chain of command starting with the department head, then the division chair, and lastly the vice president for academic affairs. Academic Dishonesty - Cheating & Plagiarism: Casper College demands intellectual honesty. Proven plagiarism or any form of dishonesty associated with the academic process can result in the offender failing the course in which the offense was committed or expulsion from school. See the Casper College Student Code of Conduct. ADA Accommodations Policy: It is the policy of Casper College to provide appropriate accommodations to any student with a documented disability. If you have a need for accommodation in this course, please make an appointment to see me at your earliest convenience.
