Edmond Mathez Curator American Museum of Natural History

Ed is a curator in the Department of Earth and Planetary Sciences at the American Museum of Natural History. Ed is an igneous petrologist, which means that he works on igneous rocks (rocks crystallized from magma or molten rock). He studies particularly large igneous rock bodies including the Stillwater Complex of Montana and the Bushveld Complex of South Africa. Both of these complexes contain economically important concentrations (ores) of platinum group metals. Ed's research on these complexes has ranged from mapping deep in the platinum mines to conducting experiments in the laboratory in order to understand how the platinum gets concentrated in the sulfide minerals in these rocks. On this cruise, Ed will put his expertise on ores to use in the study of the mineralogy of the black smoker structures, which themselves are sulfide ores. As the department chairman, Ed also is also kept busy managing the Department of Earth and Planetary Sciences, and developing the Museum's new Hall of Planet Earth.
