GEOLOGICAL SCIENCES 2Il<br />

exposed and typical Coast Range structure may be seen; and to the Grand Canyon<br />

of the Colorado River where a fascinating record of Archean, Algonkian and<br />

Paleozoic geologic history may he investigated.<br />

Required of junior, senior, and graduate students in the Division of Geological<br />

Sciences.<br />

Instructors: Buwalda, Maxson, Bode.<br />

Ge. 123. Summer Field Geology. 12 units.<br />

Prerequisites: Ge.3 a, b, c; Ge. 21 a, b.<br />

Intensive field mapping of a selected area from a centrally located field camp.<br />

Determination of the stratigraphy, fossil content, structure, and geologic history.<br />

The area chosen will probably lie in the California Coast Ranges in odd-numbered<br />

years and in the Great Basin in even-numbered years. As an occasional alternative an<br />

expedition will be conducted to localities important in California geology. The<br />

interpretations of classical localities afforded in the literature will be studied in the<br />

field. The subject begins immediately after Commencement (about June 12th).<br />

Required at the end of both the Junior and the Senior year for the bachelor's degree<br />

in the Geology courle.<br />

Instructor: Bode.<br />

Ge. 175. Elementary Geophysics. 5 units (2-0-3); third term.<br />

A lurvey of pure and applied geophysics designed mainly for geological, engineering,<br />

and other students who do not expect to enroll in specialized subjects in this<br />

field.<br />

Instructor: Peterson.<br />

Ge. 176. Elementary Seismology. 6 units (3-0-3); first term, <strong>1941</strong>-1942.<br />

A survey of the geology and physics of earthquakes.<br />

Instructor: Richter.<br />

GRADUATE SUBJECTS<br />

Courses given in alternate yea,rs are so indicated. Courses in which the enrollment<br />

is less than five may, at the discretion of the instructor, be postponed.<br />

GEOLOGY<br />

Ge. 200. Mineragraphy. 10 units (2-6-2); first term.<br />

Prerequisite: Ge. 3.<br />

Methods of identification of opaque minerals in crushed samples and polished<br />

sections, together with applications to research and practical problems.<br />

Texts: Microscopic Determination of Ore Minerals, M. N. Short; U. S. G. S.<br />

Bull., 914; Mineral Deposits, 4th edition, Lindgren.<br />

Instructors: Fraser, B. Wilson.<br />

Ge. 202. Metalliferous Deposits. 10 units (2-6-2); second term.<br />

Prerequisites: Ge. 106, 200.<br />

A study of metalliferous deposits with respect to geographic distribution, structure,<br />

alteration, and mode of formation. The laboratory work will consist of a<br />

study of ore suites and altered rocks in hand specimens, polished and thin sections.<br />

Text: Mineral Deposits, 4th edition, Lindgren.<br />

Instructors: Fraser, A. Smith.
