Ge 109 Oral Presentation. 3 units (1-0-2); third term. Practice in the effective organization and delivery of reports before groups. Successful completion of this course is required of all candidates for degrees in the division. Graded pass/fail. Instructors: Bilke, Rossman.

 Ge 114 Mineralogy.

     Ge114a. 9 units (3-4-2); first term. Atomic structure, composition, physical properties, occurrence, and identifying characteristics of the major mineral groups. The laboratory work involves the characterization and identification of important minerals by their physical and optical properties.

     Ge114b. 3 units (0-2-1); first term. Prerequisite: concurrent enrollment in Ge 114 a or instructor’s permission. Additional laboratory studies of optical crystallography and the use of the petrographic microscope.

 Ge 116. Analytical Techniques Laboratory. 6 units (1-4-1); second term. Prerequisites: Ge 114a or instructor's permission. Methods of quantitative laboratory analysis of rocks, minerals, and fluids in geological and planetary sciences. Consists of five intensive two-week modules covering scanning electron microscopy (imaging, energy-dispersive X-ray spectroscopy, electron backscatter diffraction); the electron microprobe (wavelength-dispersive X-ray spectroscopy) (Asimow); X-ray powder diffraction (Jackson); optical, infrared, and Raman spectroscopy (Rossman); and plasma source mass spectrometry for elemental and radiogenic isotope analysis (Farley). Satisfies the Institute core requirement for an additional introductory laboratory course. Instructors: Asimow, Jackson, Rossman, Farley.

 Ge 214. Spectroscopy of Minerals. 9 units (3-0-6); third term. Prerequisites: Ge 114 a, Ch 21 ab, or instructor’s permission. An overview of the interaction of minerals with electromagnetic radiation from gamma rays to microwaves. Particular emphasis is placed on visible, infrared, Raman, and Mössbauer spectroscopies as applied to mineralogical problems such as phase identification, chemical analysis, site populations, and origin of color and pleochroism. Given in alternate years; offered 2010-2011.
