and global scales: magnetic, electrical, gravity, seismic and other
methods. Three lecture hours and two laboratory hours a week for one
semester. Normally offered in the spring semester only. May not be
counted toward the Bachelor of Science in Geological Sciences, Option
II. Prerequisite: Mathematics 408D and either Physics 303L and 103N or
316 and 116L, with a grade of at least C in each. University of Texas Honor Code: The core values of The University of Texas at Austin are learning, discovery, freedom, leadership, individual opportunity, and responsibility. Each member of the university is expected to uphold these values through integrity, honesty, trust, fairness, and respect toward peers and community.
