Advising

Incoming students are assigned a faculty adviser by the graduate adviser. During the first year of study, the faculty adviser in consultation with the student selects two additional faculty members with appointments in the student’s department to complete the student’s advising committee. At the beginning of every quarter, the student’s program must be reviewed and approved by the faculty adviser.

Departmental Reviews: The Graduate Student Affairs Committee annually reviews student progress (generally in late May and early June). These reviews become part of students’ departmental records and are transmitted to the students and their faculty advisers in writing. If students’ scholarship or progress is insufficient, they may be recommended for academic disqualification.

Areas of Study

The program in geochemistry offers study in biogeochemistry, environmental geochemistry, experimental petrology, geobiology, isotopic studies of stable and radioactive elements, marine geochemistry, meteorite research, mineral physics, paleoclimate, and planetary science. Other comparable areas of study are also possible.

Foreign Language Requirement

None.

Course Requirements

Full time students must enroll in a minimum of 12 units per quarter. The twelve units required per quarter may include, among others, courses in the 500 series (individual study or research).

Each course of study is individually created by the advising committee in consultation with the student. It may include appropriate courses offered by other departments.

Nine graduate and upper division courses (36 units) are required for the degree; at least six of those courses (24 units) must be 200-series and offered for a letter grade. Students may apply up to 8 units of 596: Directed Individual Study and/or Research toward the total course requirement and the graduate course requirement.

Generally, students in this program are expected to attain, either through previous training or through prescribed course work, a common mastery of the subject matter in the following five courses: Earth, Planetary, and Space Sciences C206: Physical Geochemistry; EPSS C207: Geochemistry; EPSS C209: Isotope Geochemistry; Chemistry 110A: Physical Chemistry: Chemical Thermodynamics; Chemistry 110B: Physical Chemistry: Introduction to Statistical Mechanics and Kinetics.

In addition to the above requirements, all students are required to enroll each quarter in a Geochemistry seminar (Earth, Planetary, and Space Sciences 235A, 235B, 235C: Current Research in Geochemistry) or Geology seminar (Earth, Planetary, and Space Sciences 245A, 245B, 245C: Current Research in Tectonics) and present at least one lecture in that seminar during each academic year. All students are required to enroll each quarter in the EPSS weekly colloquium (EPSS 295 A, B, C).

Teaching Experience

Not required.

Field Experience

Not required.

Capstone Plan

The comprehensive examination is scheduled by the faculty adviser in consultation with the student and other members of the examining committee. The examining committee consists of the faculty adviser and at least two additional EPSS faculty members. In extraordinary circumstances, a delay or change in committee membership may be granted by petition to the graduate adviser or department chair.

The student prepares two written research proposals on two dissimilar projects approved by the faculty adviser. The proposals must be concise, with a guideline of 4 pages and a maximum of 5 pages, and must be submitted to the examining committee at least 10 days before the examination. The proposals are presented briefly to the examining committee orally, and the committee examines their originality and scientific merit, as well as the student’s fundamental knowledge in the program area.

Thesis Plan

Every master’s degree thesis plan requires the completion of an approved thesis that demonstrates the student’s ability to perform original, independent research.

The thesis must be approved by the student’s thesis adviser, as well as by the other members of the student’s advising committee. If students choose the thesis plan, no examination is required.

Written and Oral Qualifying Examinations

Academic Senate regulations require all doctoral students to complete and pass university written and oral qualifying examinations prior to doctoral advancement to candidacy. Also, under Senate regulations, the University Oral Qualifying Examination is open only to the student and appointed members of the doctoral committee. In addition to university requirements, some graduate programs have other pre-candidacy examination requirements. What follows in this section is how students are required to fulfill all of these requirements for this doctoral program.

All committee nominations and reconstitutions adhere to the Minimum Standards for Doctoral Committee Constitution.

Departmental Written and Oral Preliminary Examination: This examination must be taken no later than the spring quarter of the second year. It is scheduled by the faculty adviser in consultation with the student and other members of the examining committee. The examining committee consists of the faculty adviser and at least two additional EPSS faculty members. In extraordinary circumstances, a delay or change in committee membership may be granted by petition to the graduate adviser or department chair.

The student prepares two written research proposals on two dissimilar projects approved by the faculty adviser. The proposals must be concise, with a guideline of 4 pages and a maximum of 5 pages, and must be submitted to the examining committee at least 10 days before the examination. One of the proposals should cover a possible dissertation topic.  The proposals are presented briefly to the examining committee orally, and the committee examines their originality and scientific merit, as well as the student’s fundamental knowledge in the program area.

The possible outcomes of this examination are:

1. Pass — with immediate eligibility to proceed to the University Oral Qualifying Examination.
2. No-pass — with the possibility of reassessment by an agreed upon date (in consultation with the committee and the student) on the basis of a specific written list of requirements supplied by the graduate evaluation committee.  This option is meant for students with identifiable and presumably correctable weaknesses, but who are otherwise above the passing threshold.  The no-pass option can only be used once for any particular student.
3. Terminal master’s pass — allowing the student only to finish any outstanding course requirements for the master’s degree.
4. Fail — resulting in a recommendation for academic disqualification.

University Written and Oral Qualifying Examination: After passing the departmental qualifying examination, students must consult their faculty adviser and the graduate adviser regarding nomination of the doctoral committee. In consultation with the doctoral committee, students arrange a time for the oral qualifying examination. This examination is normally taken in the spring quarter of the third year, and must be taken no later than the spring quarter of the fourth year. At least 10 days before this examination, students must provide each member of the doctoral committee with a written prospectus of their proposed dissertation research, including a summary of research objectives, methodologies, and a timeline for completion. During the oral qualifying examination, the committee may examine the student’s fundamental knowledge in the discipline in addition to the proposed research. Repetition of a failed examination is at the option of the doctoral committee.

Advancement to Candidacy

Students are advanced to candidacy and awarded the Candidate in Philosophy (C.Phil.) degree upon completion of the written and oral qualifying examinations.

Doctoral Dissertation

Every doctoral degree program requires the completion of an approved dissertation that demonstrates the student’s ability to perform original, independent research and constitutes a distinct contribution to knowledge in the principal field of study.

Final Oral Examination (Defense of the Dissertation)

Not required for all students in the program. The decision as to whether a defense is required is made by the doctoral committee.

Time-to-Degree

1. The departmental preliminary examination is normally taken in the second year of residence.
2. The university qualifying examination is normally taken in the third year and no later than the fourth year of residence.
3. The dissertation and dissertation defense are normally completed no later than the fifth year of residence.

Academic Disqualification and Appeal of Disqualification

University Policy

A student who fails to meet the above requirements may be recommended for academic disqualification from graduate study. A graduate student may be disqualified from continuing in the graduate program for a variety of reasons. The most common is failure to maintain the minimum cumulative grade point average (3.00) required by the Academic Senate to remain in good standing (some programs require a higher grade point average). Other examples include failure of examinations, lack of timely progress toward the degree and poor performance in core courses. Probationary students (those with cumulative grade point averages below 3.00) are subject to immediate dismissal upon the recommendation of their department. University guidelines governing academic disqualification of graduate students, including the appeal procedure, are outlined in Standards and Procedures for Graduate Study at UCLA.

Special Departmental or Program Policy

In addition to the standard reasons outlined above, a student may be recommended for academic disqualification who fails to meet requirements regarding course scheduling and deadlines for completion of examinations or the degree. A student may appeal a recommendation for academic disqualification through a letter to the graduate adviser or the department chair.
