<p> Field techniques</p><p>Geology 111A Spring 2009</p><p>Course objectives and activities This course is designed to provide upper division geology majors with the theory and techniques that will lead to basic geologic mapping skills. We will use a Brunton compass to estimate elevations, measure bearing, trend, strike and dip, resect, and triangulate. We will also use pace and compass techniques to construct simple maps, with emphasis on accuracy and closure. Several weeks will be spent learning how to assemble the basic components of a geologic report, including introduction and regional geology, location map, structural cross section, stratigraphic column, geologic map, map key, and geologic history. We will also use computer graphics packages (Powerpoint or similar) to make templates for some of the required figures.</p><p>Course format Lecture one hour per week, lab three hours per week. Many of our lab exercises will be outdoors, so dress for the weather. We will work outside in moderate rain if necessary.</p><p>Instructor Dr. Tim Horner, 1018 Placer Hall, (916) 278-5635, e-mail [email protected]. Office hours Tuesday 12:00-1:30 and Thursday 10:30 – 12:00 or by appointment.</p><p>Grading Grades will be based entirely on weekly assignments. All written assignments must be spell-checked and word-processed, with 1 inch margins, 12 or 13 point font, and appropriate captions for all figures or tables. Late projects lose 1 letter grade for each day late. Missed exercises without prior arrangement will be given a grade of zero. Academic misconduct will result in a grade of zero for that exercise, and may be reported to the Geology Department or the Dean of Student Affairs.</p><p>Equipment and supplies</p><p>You will need a variety of field equipment, drafting supplies and camping equipment for this class. A partial list includes the following materials:</p><p>Field notebook Clip board with cover Drawing pencils: HB, B, 2B, 4B Pouch or pack for field mapping supplies Drafting eraser 3 Fine-point drafting pens (felt tip is acceptable) Small triangle Ruler or engineering scale Set of at least 10 soft colored pencils Map scales: 20 and 30 scales with protractor</p><p>1 Text and reading</p><p>Compton, 1985, Geology in the field.
