Research

Robert Creaser specializes in radiogenic isotope geochemistry using the Re-Os, Rb-Sr, Sm-Nd, Pb-Pb isotope systems. A wide variety of geochemical phenomena and processes, mainly involving the geochemistry, origin and evolution of Earth's crust, are investigated using these isotope systems. Currently, research projects focus on the use of Re-Os isotopes for geochronology, such as: Re-Os geochronology and systematics of organic-rich sediments (black shales), application of Re-Os isotopes for direct dating of hydrothermal sulfide mineralization, Re-Os geochronology of fluid flow in sedimentary basins. Research opportunity:

Geochronology of fluid flow in sedimentary basins using Re-Os isotopes.
Re-Os geochronology of hydrothermal ore-forming systems using sulfide minerals.

Courses

EAS 100 - Planet Earth

Introduction to the origin and evolution of the Earth and the solar system. Introduction to plate tectonics and the rock cycle. Simple energy balances and interactions between radiation and the atmosphere, land, oceans, ice masses, and the global hydrological cycle. Evolution of life, biogeography, and global climate in the context of geologic time. The carbon cycle. Human interaction with the Earth. Mineral and energy resources. This course may not be taken for credit if credit has been obtained in EAS 200 or 201.
