Susan Halgedahl is a geologist known for her research into the physics that govern magnetic rocks and for her work on fossils from Utah's Wheeler Formation.
[1][2] She subsequently worked at ARCO Oil and Gas Company and Lamont-Doherty Geological Observatory before moving to the University of Utah in 1993.
[1] As of 2021, Halgedahl is an Associate Professor Emerita in the Geology and Geophysics Department at the University of Utah.
[1] For her Ph.D. research, Halgedahl investigated rocks that retain their magnetic orientation, such titanomagnetite,[3] in samples from the Ocean Drilling Program.
[7] The magnetic signal in rocks can be used to reconstruct the development of the Arctic Basin over geologic time.
