We will learn:
to identify 75 common minerals.
to identify the crystal classes, crystal axes and faces and mineral groups represented.
to determine the Miller Indices of crystal faces and to use them in crystal descriptions.
to use Stereographic Projections.
to recognize twinning and the information twinning provides for understanding the history of a mineral.
to be familiar with the Bohr model of the atom.
to know Pauling’s Rules for ionic crystals.
to know the theory of x-ray crystallography, and know how to identify an unknown mineral from x-ray powder diffraction pattern.
to know with the general structure of the principal silicate minerals.
to read phase diagrams and to apply the Phase Rule to a number of binary and ternary phase diagrams in order to interpret the crystallization processes of various types of igneous systems.
Labs will be integrated with the lecture material and coordinated with it. The class will consist of a lecture followed by a period of observation in lab and with the aid of computers, of on-line examples of the minerals and rocks being covered.

General Requirements and Grading System
a) Attendance: Attendance is required. A positive and upbeat attitude toward the subject will help make the class a rewarding experience.
b) Quizzes: Weekly quizzes will be given over the assigned reading material. - 20%
c) Practicals. Three practical exams will be given. These will cover the lab and lecture work. The third of these will be a component of the comprehensive final - 40%
d) Final Exam. The final exam will be comprehensive and will cover the entire scope of the course, and will include the third sectional exam. The comprehensive portion will be more general than the sectional exams, and will be of the same nature. - 40%
