Exercise #1 Due BEFORE CLASS on September 8, 2010 Rules: You may use any reference you would like. You are encouraged to help each other, but please write your own answers. Neatness counts (use a clean sheet of paper and make your drawings sufficiently large and your calculations neat). Show all work. Remember, no late work is accepted. Through X-ray diffraction, you determine the unit cell dimensions (in Å) and angular relationships for the following minerals. Clinozoisite: Unit cell: a = 8.98, b = 5.46, c = 10.22;
