Gravity and Magnetic Investigation of the Blue Mountains Province, NE Oregon

 MS Thesis, Babs Horrighs, 2008

Babs Horrighs is working on her MS thesis collecting and analyzing gravity and magnetic data to determine the tectonic structures within the Blue Mountains Province in NE Oregon. More specifically she is interested in the Izee terrane between John Day and Burns Oregon. Dr. Rebecca Dorsey of the University of Oregon suggested the project and is involved in the interpretation of the data. The project was funded by a Missouri State University faculty research grant to Mickus.

Some pictures of the gravity data collection in June/July 2008 are shown on the next two pages.
