Understanding of atomic structure, radioactive decay, mass spectrometry, dating techniques and petrologic uses of isotropic systems. Emphasis will be placed on evaluating dating methods in relation to particular geologic problems and possible sources of error. The use of isotopes in defining magmatic sources and crustal contamination are discussed. Prerequisites: CHEM 1020, CHEM 1110, MATH 2200, MATH 2205. 1/27/2020 - 5/8/2020, Lecture, GE, 213
