CLASS MEETING TIMES Lecture : 9:20 – 10:20 am MWF Room: JSC 226 Lab: 12:40 – 3:30 pm Tuesday Room: JSC 226 7 – 9:50 pm Tuesday Room: JSC 226

ATTENDANCE and ETIQUETTE Regular attendance is required for all lectures and laboratories. This will be a fast-paced course and it is critical to your understanding of the material that you be present at all times. Please be on time for the beginning of class and unless it is an emergency, please do not walk out during class time – this is very distracting to your peers and me.

HOMEWORK and PROJECTS A series of homework and project assignments will be given during the course of the semester. No late assignments will be accepted.

EXAMINATIONS

One-hour exams are scheduled approximately every three to four weeks. See the attached lecture syllabus for the appropriate dates. NO MAKE-UP EXAMS WILL BE GIVEN EXCEPT FOR DOCUMENTED EMERGENCIES. The final exam will be given on the scheduled date and will be COMPREHENSIVE. The final exam MAY NOT be taken at any other time than the officially scheduled time.

GRADING

Grades will be determined based on the criteria listed below: One-hour exams 30% (10% per exam) Final exam 15% Quizzes and Projects 15% Homework 10% Laboratory Work and 30% Lab Quizzes

GRADE SCALE A 100-93% C+ 79-77% A- 92-90% C 76-74% B+ 89-87% C- 73-70% B 86-84% D+ 69-67% B- 83-80% D 66-64%

D- 63-60% F <60%

ACADEMIC HONESTY

Any act that places a student in unfair advantage with respect to the rest of the class will be treated according to the University procedures outlined in the Student Handbook.

LABORATORY SYLLABUS The laboratory portion of this course is critical to your understanding of Physical and Optical Mineralogy. Thus it is expected that you will attend all labs and be in lab during the assigned lab time. We will use the lab time to go over new lab assignments and review the previous weeks’ assignment. Most, if not all of the labs will require a significant amount of outside work on your part. There will be a lab practical during the last lab period of the semester. Failure to turn in three or more completed labs will result in a course grade of 'F' regardless of your performance in other portions of the course. Week Topics Mineral Unknowns Aug. 31 Interfacial Angles, Symmetry Specimens 1-10 Sept. 7 Crystal Classes, Symmetry 11-20 14 Crystal Forms, Miller Indices 21-30 21 Stereonets 31-40 28 Twins and Pseudomorphs 41-50 Oct. 5 The Polarizing Microscope 51-60 12 Isotropic Minerals, Refractive Index 61-70

JOURNALS

American Mineralogist A very technical journal covering all aspects of mineral formation, thermodynamics and equilibrium. Canadian Mineralogist Same style as American Mineralogist. Contributions to Mineralogy and Petrology A very technical journal covering mostly igneous rocks, but occasionally an article on minerals. Economic Geology A technical journal on ore deposits and their associated minerals. Mineralogical Record A laymen's journal on specific minerals

and their occurrence. Beautiful photos of mineral specimens and collecting information.

Rocks and Minerals A laymen's magazine on popular minerals and how and where to collect them.

OUTSIDE READING MATERIALS Many times reading the textbook discussion of a particular topic will be difficult to understand. There are many other books available on mineralogy, crystallography, and optical mineralogy that are available in the Prevo library that may help you to better understand a particular topic. I strongly encourage you to use these texts.
