Abstract:

Body wave travel-times, surface wave dispersion, and gravity data have been used to refine the structural details of the crust and upper mantle within the northern Basin and Range. The crust varies in thickness from 35-40 km SE of Reno to 28 km in the western Battle Mountain heat flow high and 45-50 km in central Oregon. The mantle lid structure derived from fundamental mode surface wave data has been confirmed by higher mode surface wave data. Fundamental and higher mode dispersion data for southern Nevada and Arizona indicate the structure of the southern Basin and Range is similar to that of the Great Basin.
