108 11. Our National Parks and Monuments. Brief survey of the geographic and geologic features that make the National Parks and Monuments outstanding. One four-day field trip required for which a special fee is to be paid. Three quarter hours. Autumn. Buss Geology 1. General Geology. The earth, its rocks and minerals, its surface and subterranean features, their origin and their causes as revealed in land features. Two field trips required. Four lectures and one laboratory period a week. Five quarter hours. Autumn, Winter, Spring. BUS3 3. Historical Geology. The history of the earth, from its theoretical origin to the present as interpreted from the rocks and their fossil contents. North America, particularly Utah and the adjacent areas, is emphasized. Two required field trips provide a valuable supplement to class discussion. Prerequisites: Geology 1 or Geology 11. Five quarter hours. Spring. Buss 5. Rocks and Minerals. Sight recognition of the important rock- forming and other minerals through class discussion and laboratory work, and the identification of the common rocks of the earth's crust by mineral content, association and occurrence. Field trips are required. Three lectures and one laboratory period a week. Four quarter hours. Autumn. Buss 6. Gemology. Physical and other properties of the minerals and rock minerals by physical, chemical and blowpipe tests. Prerequisites: Geology 1 or 11, and Chemistry 2 or 5, or permission of the instructor. One lecture and two laboratory periods a week. Three quarter hours. Winter. Buss 7. Mineralogy of Rock Minerals. Fundamentals of crystallography, and the identification, and sight recognition of the more important rock minerals by physical, chemical and blowpipe tests. Prerequisites: Geology 1 or 11, and Chemistry 2 or 5, or permission of the instructor. One lecture and two laboratory periods a week. Three quarter hours. Winter. Buss 109 8. Mineralogy of Ore Minerals. The minerals studied are those most important as ores. Prerequisite: Geology 7. One lecture and two laboratory periods a week. Three quarter hours. Spring. Buss 9. Petrology. Sight recognition of rocks and a study of their classification and occurrence. Two lectures and one laboratory period a week. Prerequisite: Geology 7. Three quarter hours. Spring. (May not be given.) Buss 11. Physical Geology. Similar to Geology 1 but with emphasis on geological features important in engineering and forestry practice. Designed for geology majors, engineering, and forestry students. Credit is not given for both Geology 1 and Geology 11. It is recommended that physics and chemistry be taken previously or concurrently with this course. Field trips are required. Three lectures and one laboratory period a week. Four quarter hours. Winter, Spring. Buss 14. Regional Geology. A continuation of Geology 1 or 11 and Geology 3 but with emphasis on the various regions of the United States, their geological development and correlations. Prerequisite: Geology 3. Four quarter hours. Spring. (May not be given.) Buss 16, Elementary Field Geology. The fundamentals of geology as they are observed in Western United States and adjacent areas during the six-weeks' field trip. Three or four quarter hours. Summer. (May not be given.) Buss 17. Advanced Field Geology. The fundamentals of geology applied to an interpretation of geology features visited during a six- weeks field trip. Prerequisites: Geology 1 and 3. Three or four quarter hours. Summer. (May not be given.) Buss 25. Geological Mapping. An elementary course in mapping geologic phenomena. Two laboratory periods a week. Prerequisite: Geology 1 and 3. Two quarter hours. Spring. Buss 40. Geological Literature. Designed to acquaint the student with geologic literature and to enable him to give oral reports on his work. Prerequisite: Geology 1 and 3. Oone quarter hour. Autumn, Winter, Spring. Buss
