Informationen zum Autor George H. Davis is the Provost and Regents Professor of the Geosciences, University of Arizona.?He received his Ph.D. in Economic Geology from The University of Michigan, Ann Arbor, and his MA in Structural Geology from The University of Texas, Austin. Stephen J. Reynolds is Associate Professor of Geology, Arizona State University. He received his masters and Ph.D. in Geosciences from the University of Arizona. Dr. Reynolds has received the ASU Department of Geology Outstanding Teacher Award three times and has been nominated for the College of Liberal Arts and Sciences Distinguished Teaching Award, 1993. Klappentext Relates the physical and geometric elegance of geologic structures within the Earth's crust and the ways in which these structures reflect the nature and origin of crystal deformation through time. The main thrust is on applications in regional tectonics! exploration geology! active tectonics and geohydrology.
