Surface Waves, Seismic Refraction and Upper Mantle Structure of the Basin and Range

摘要

Earlier study of Great Basin structure using surface waves have been extended to include the Southern Basin and Range of Arizona, and the Volcanic Plateau of Northern Nevada and Southern Oregon. The crust of the Southern Basin and Range is slightly thinner than that of the Great Basin while the mantle structure is similar. The Volcanic Plateau has a thicker crust (based on refraction data) than the Great Basin while the mantle lid zone is either thin or absent. (Author)
