Abstract

Estimates of surface extension in the southern Basin and Range province and transition into the Colorado Plateau range from a few percent to several hundred percent locally, yet the crustal thickness varies perhaps only 10-15km across these provinces. Within the southern Basin and Range and the metamorphic core complex belt, extremely extended crust is directly juxtaposed against equally thick (or thinner) crust that underwent far milder extension. Unless preextension crustal thickness varied dramatically over a short distance, the crust must have maintained its thickness during extrusion, through mechanisms that involve crustal flow and magmatism. A 300km-long profile of seismic refraction and coincident vertical-incidence reflection data are employed to investigate the geophysical signature of these processes from the extended southern Basin and Range province to the unextended Colorado Plateau. -from Author
