GEOL B101 How the Earth Works

 An introduction to the study of planet Earth--the materials of which it is made, the forces that shape its surface and interior, the relationship of geological processes to people, and the application of geological knowledge to the search for useful materials. Laboratory and fieldwork focus on learning the tools for geological investigations and applying them to the local area and selected areas around the world. Three lectures and one afternoon of laboratory or fieldwork a week. One required one-day field trip on a weekend.

GEOL B110 Focus: Exploring Mars

 In this introductory-level course, students will explore the geologic history of Mars, focusing on current landers and satellites exploring Mars right now. In addition to examining major outstanding controversies about the history of past water and possible life on Mars, students will learn how to use data from on-going missions to explore key regions of Mars themselves. No prerequisites.

GEOL B202 Mineralogy and Crystal Chemistry

 The crystal chemistry of representative minerals, descriptive and determinative mineralogy, as well as the relation between the physical properties of minerals and their structures and chemical compositions. The occurrence and petrography of typical mineral associations and rocks is also covered. Lecture three hours, laboratory at least three hours a week. One required field trip on a weekend. Prerequisite: introductory course in geology or chemistry (both recommended).

GEOL B299 Geology Field Short Course: Geology of Death Valley In pre-trip class meetings, students engage in a forum for discussing assigned readings. During the week-long field trip, students are exposed to geologic field methods while visiting sites that exemplify different geology from that at sites near campus. Geologic methods introduced include proper field note-taking, mapping and measuring geologic structures, and interpreting geologic history. Culminating work introduces students to geologic illustration and report writing. A passing grade requires full participation and engagement by the student before, during and after the field trip. Post-trip meetings will synthesize the material covered, and to go over students' final reports. Prerequisite: GEOL B101, B102 or B103; and GEOL B202, B203, B204 or B205.

GEOL B302 Low-Temperature Geochemistry The geochemistry of Earth surface processes. Emphasis is on the chemistry of surface waters, atmosphere-water environmental chemistry, chemical evolution of natural waters, and pollution issues. Fundamental principles are applied to natural systems with particular focus on environmental chemistry. One required field trip on a weekend. Prerequisites: CHEM 103, 104 and GEOL 202 or two 200-level chemistry courses, or permission of instructor

GEOL B305 Igneous and Metamorphic Petrology The origin, mode of occurrence, and distribution of igneous and metamorphic rocks. The focus is on the experimental and field evidence for interpreting rock associations and the interplay between igneous and metamorphic rock genesis and tectonics. Three lecture hours weekly. Occasional weekend field trips. Prerequisites: GEOL 202.

GEOL B350 Advanced Topics in Geology: Planetary Science Principles and geologic histories of the solid bodies in the Solar System: rocky planets, icy moons, asteroids, and comets. How and why these bodies vary in volcanism, tectonics, atmospheric dynamics, aqueous environments, and other planetary processes. Students will read and discuss primary literature, and examine data from on-going NASA planetary missions. Prerequisites: advanced standing in geology, astronomy, or physics, or permission of the instructor.

GEOL B350Praxis: Acid Mine Draiange

 In this class, we partner with scientists and environmental activists from the Schuylkill Headwaters Association, a citizen watch group dedicated to cleaning up water quality in the headwaters region of the Schuylkill River.   Together, the students design and execute a semester-long research project, addressing some aspect of geochemistry and environmental remediation of Acid Mine Drainage systems in the Schuylkill headwaters region.  The area, about 2 hours northwest of Bryn Mawr, is the source of most of the drinking water for the greater Philadelphia area, and suffers from significant acidification and heavy metal contamination of waters due to local abandoned coal mines. This hands-on class will involve significant amounts of field and laboratory work.  Prerequisites: Junior or Senior standing in Geology or Chemistry, or permission of the instructor.

GEOL B350 Advanced Topics in Geology: Petrotectonics

 This course introduces topics that intersect the disciplines of petrology and tectonics (Petro-Tectonics), e.g. mantle and lithosphere evolution, crustal growth processes, and the structure and mechanics of collisional and extensional orogens. A wide range of concepts will be covered that integrate mantle and lithospheric processes into global plate tectonic framework. Prerequisites Geo 202 and 204.

GEOL B399 Senior Capstone Seminar

 A capstone seminar course required for all Geology majors. All Geology seniors will be required to participate in this two-semester seminar that meets weekly for 1.5 hours for a total of 1.0 credit (0.5 credits per semester). Enrollment required in two half-credit courses, one in the fall and one in the spring semester of the senior year. The focus of the seminar will be to integrate the student's major curriculum into open peer-led discussions on cutting edge research in the many diverse fields of Geology, to discuss the impact and relevance of Geology to modern society, and to work on oral and written communication skills.
