Geology

Overview

The mission of the Geology major is to foster in students an understanding of the Earth: the processes that affect its surface and interior; its formation and evolution through time; and its functioning as the physical environment for the living world. The major accomplishes this goal by offering to students a set of coordinated experiences in the classroom, laboratory, and field. Geology is an intrinsically interdisciplinary science, drawing upon the tools of mathematics, physics, chemistry, biology, geography, and environmental science to examine problems that range in scale from a single mineral grain to the entire solar system. Geology majors learn to work together on inquiry-based laboratory and field projects, and each produces a Senior Thesis describing independent research they have undertaken with a faculty mentor. There is a special emphasis on articulating ideas orally, graphically, and in writing, skills that are valuable not only in science but also in the many other careers where geology majors from Occidental have found success. Geology is a global science, and so students who have made progress in the major as sophomores are encouraged to study abroad for a semester during their junior year. The Geology major expresses the Department's commitment to prepare students to excel in an increasingly complex and environmentally stressed world.

GEO 105 is open to first-year and second-year students only; 200-level courses are open to any student who has completed GEO 105; 300-level courses are intended for junior and senior geology majors and minors; 400-level seminars are for senior majors.

Major Requirements

Students are required to complete all departmental requirements and supporting coursework as detailed below.

COURSEWORK

Supplemental Coursework:

Students are required to complete two additional courses to complete the major: one in Statistical Analysis and the other in Quantitative Literacy.

Statistical Analysis

Select one course from the list below:

Quantitative Literacy

Supplemental Coursework:

Students are required to complete two additional courses to complete the major: one in Statistical Analysis and the other in Quantitative Literacy.

Statistical Analysis

Select one course from the list below:

Quantitative Literacy

Select one course from the list below. Note: students who pass out of MATH 110 are required to take an additional quantitative literacy course at the college level.

Honors in the Major

Students with a GPA of at least 3.25 are eligible to graduate with honors in geology. For these students, a larger senior thesis is planned, and students start their research earlier than the fall of their senior year. For this extra work, the honors student receives additional course credit (GEO 499) beyond credit for comprehensives.

Geology Minor

Fundamental Coursework

Electives

In addition to the required Fundamental Coursework, students must complete two additional GEO courses.

Second-Stage Writing

Students majoring in Geology will satisfy the Second-Stage Writing Proficiency requirement by submitting a portfolio of at least two papers from any of the intermediate- or advanced-level writing-intensive Geology courses normally required for the major (or appropriate course work). The portfolios will be evaluated by at least two faculty members using the departmental writing rubric. Students receiving a passing score on the portfolio will fulfill the requirement; a student who does not receive a passing score will be required to submit his/her major writing intensive paper/project from GEO 391 Research Methods.

Students should familiarize themselves with the departmental requirement at the time of declaring the major. See the Second-Stage Writing Proficiency requirement in the college catalog and consult the department chair for additional information about which courses will fulfill the requirement and for a copy of the department's evaluation rubric.

Comprehensive Requirement

The comprehensive requirement in Geology is met by a passing grade on the senior comprehensive project. The senior comprehensive project is based on research conducted under the supervision of Department faculty or in an off-campus summer research program or field camp. This project can be started as early as the junior year (GEO 391) and typically involves field or laboratory work during the summer between junior and senior years. Seniors are expected to present their research orally and submit a written thesis by Spring Break. During the fall semester of senior year, all Geology majors attend a senior seminar (GEO 491 or equivalent). A major goal of these meetings is to help students make timely progress on their comprehensive projects.

Transfer Credit Policies

The Geology Department policy on transfer credit conforms to College policy. Students should reference the Transfer Credit section for details.

Advising Information

Students interested in majoring in Geology should consider taking GEO 105 (Earth: Our Environment) or GEO 106 (Earth and the Human Future) during their first year. Either of these courses can be used to fulfill the prerequisite for subsequent courses in the major.

All Geology majors must complete Calculus I (MATH 110 or MATH 114). In addition, majors must complete either Calculus II (MATH 120 or MATH 128) or a department-approved statistics course. Geology is a global science, and so students who have made progress in the major as sophomores are encouraged to study abroad for a semester during their junior year. Though not required for the major, students considering graduate school or professional careers in geology or environmental science are encouraged to take CHEM 120 or CHEM 130; PHYS 110 or PHYS 115; and PHYS 125 or PHYS 230.

Placement Information

Most students who are interested in majoring in geology should take the Calculus Placement Assessment (ALEKS) during the summer prior to their first year. You do not need to take the Calculus Placement Assessment if you any of the following are true:

• You received a score of 4 or 5 on either the AP Calculus AB or BC exam;

• You receive an IB Calculus HL score of 5 or above;

• You have already taken a Calculus 1 course at another accredited college or university. Courses that have not been pre-approved by the Math department will need to be filed by submitting the Transfer Credit & Course Substitution Form.

Sample 4-Year Plan

No Concentration

Major with a concentration in Environmental Science

Curricular Notes

• To complete all core requirements by the sophomore year, at minimum, one course will need to satisfy two core requirements.

• With the Geology major Environmental Science Concentration, there is great flexibility with regards to when a course needs to be taken.  Many students take their first GEO 105 course during Year 2.

• There are two options for fulfilling the mathematics component of the major:

• An AP Calculus AB score of 4 or 5 fulfills the Calculus 1 requirement. 

• An AP Calculus BC score of 4 or 5 fulfills the Calculus 2 requirement.

• The required 200-level GEO courses can be taken in any order. 

• GEO 220 and GEO 225 are a prerequisite for some GEO 300-level courses

• For the Environmental Science concentration: To complete the Biology Component, students must take one course from BIO 105, BIO 110, or BIO 115, and either BIO 260 or BIO 270.

Geology Transfer Student Advice

Transfer Course Limit for Transfer Students: No Limit

Designated Transfer Adviser

Expected preparation for transfer students wanting to major in Geology:

• Students transferring in as juniors must have completed a course equivalent to our GEO 105. Completion of additional Geology courses and/or a statistics course is recommended.

General advice for transfer students wanting to major in Geology:

• Early consultation with the department chair is essential.

What courses should a transfer student take during their first semester at Occidental?

• Junior transfers should take one or two 200-level GEO courses during their first semester, as well as a math or statistics course if needed.

• All other transfer students should take GEO 105. If they have already completed a GEO 105 equivalent, they should take another GEO course. COMP 146 is also highly recommended for students who have not yet completed a statistics course.
